Robotic Pancreaticoduodenectomy: Technical Considerations

2017

Robotic surgery can help to overcome some technical limitations of laparoscopic pancreaticoduodenectomy thanks to EndoWrist instrumentations and the 3D view. Despite the potential benefits, its employment is still low and controversial. We focused on some important technical details crucial for a safe robotic pancreatectomy. After performing 52 robotic pancreatic resections that included 10 pancreatoduodenectomies, the authors describe their technique. The review of literature on robotic and laparoscopic duodenopancreatectomy is also performed in order to evaluate possible benefits of the robotic platform. We describe the step-by-step surgical procedure, analyzing all possible troubleshooti…

A 3D totally absorbable synthetic mesh in antireflux surgery: Gore Bio-A tissue reinforcement for hiatal hernia repairing

2015

Introduction Hiatal hernia, defined as “transitory or stable dislocation of a part of the stomach in mediastinum through the diaphragmatic crura delimiting esophageal hiatus”. Its appearance presupposes anatomic anomalies or weakening of structures and mechanisms able to maintain esophago-gastric junction and stomach in the abdominal cavity [1]. Classically hiatal hernia was classified in four types using Hill’s classification: Type 1 hiatal hernia is associated with GERD in 50-90% of cases, in facts its presence gradually compromises esophago-gastric junction’s continence favouriting the backwater of acid secretion and its reflux in contact with esophageal mucosa during transient relaxatio…

The prevalence of post-thyroidectomy chronic asthenia: a prospective cohort study

2017

Chronic asthenia (CA) is complained by some patients that have undergone thyroid surgery. We evaluate its impact in patients undergoing unilateral or bilateral thyroidectomy, the trend during a 1-year follow-up, and the possible risk factors. A prospective, cohort study was carried out on 263 patients scheduled for thyroidectomy from 2012 and 2014. Exclusion criteria were as follows: Graves’ disease, malignancies requiring radioiodine therapy, post-surgical hypoparathyroidism, laryngeal nerve palsy, abnormal pre- and post-operative thyroid hormone levels, and BMI outside the normal range.

The non-surgical management for hemorrhoidal disease. A systematic review

2017

The non-surgical treatments for hemorrhoids are cost and time-saving techniques usually performed in patients suffering early hemorrhoidal disease. The most used are rubber band ligation (RBL), injection sclerotherapy (IS), and infrared coagulation (IRC). We performed a systematic review in order to evaluate: do these procedures really help to avoid further more aggressive treatments? What are the common harms? What are the rare harms? How many recurrences there are? A total of 21 RCTs were included in this review: 12 on RBL, 4 on IRC and 5 on IS. In RBL bleeding stops in up to 90% and III degree hemorrhoids improves in 78%-83.8%. IV degree prolapse should have a more invasive treatment. Th…

The coexistence of primary hyperparathyroidism and thyroid nodules: Should the preoperative work-up of the parathyroid and the thyroid diseases be sp…

2016

Introduction and objectives. Primary hyperparathyroidism (PHPT) can be found in concomitance with thyroid disease (TD) in a high frequency of cases. In this context the diagnostic exams for localizing the enlarged parathyroid(s) gland(s) could be less reliable or nonconclusive. Moreover, the thyroid carcinoma seems to be more frequent compared to that isolated thyroid desease and, therefore, carefully investigated. The main goal of the present study is to evaluate which diagnostic tool (US, MIBI) is more reliable for localizing the site of the PTH hypersecretion and to confirm if it is always advantageous a combination of both exams. Besides, we evaluated the incidence of thyroid carcinoma …

4843delC of the BRCA1 gene is a possible founder mutation in Southern Italy (Sicily).

2007

Various studies have been published in Italy regarding the different BRCA1 mutations, but only the BRCA1-5083del19 mutation is recurrent and specific to individuals of Italian descent with a founder effect on the Calabrian population. In our previous study, BRCA1-5083del19 mutation carriers were found in four index cases of 106 Sicilian patients selected for familial and/or hereditary breast/ovarian cancers. The high frequency rate of this mutation identified in the Sicilian population led us to perform haplotype analysis in all family carriers. Five highly polymorphic microsatellite markers were used (D17S1320, D17S932, D17S1323, D17S1326, D17S1325) to establish whether or not all these fa…

Deep seroma after incisional hernia repair. Case reports and review of the literature.

2015

Wound-related complications are common after incisional hernia repair with mesh; seroma formation is the most frequent problem. The formation of a deep seroma has been rarely reported in the literature.In one year, September 2012-2013, 136 patients underwent surgery for incisional hernia repair, both elective and urgent.The following complications were observed: one dislocation of polypropylene prosthesis, a massive relapsed seroma and two deep seromas described in this article. A 63- years-old female underwent open incisional hernia repair with an intraperitoneal PTFE patch. She developed recurrent seroma under the mesh drained percutaneously, and finally the prosthesis was removed. A 72- …

Muscle degeneration in inguinal hernia specimens.

2012

BACKGROUND: There are few articles in the literature reporting the histological changes of groin structures affected by inguinal hernia. A deeper knowledge of this matter could represent an important step forward in the identification of the causes of hernia protrusion. This study aimed to recognise the pathological modifications of muscular structures in autopsy specimens excised from tissues surrounding the hernia orifice. METHODS: Inguinal hernia was identified in 30 autopsied cadavers, which presented different varieties of hernia, including indirect, direct and mixed. Tissue specimens were resected for histological study from structures of the inguinal area surrounding the hernia openi…

Surgeon volume and hospital volume in endocrine neck surgery: how many procedures are needed for reaching a safety level and acceptable costs? A syst…

2018

The relationship between quality of care and provider's experience is well known in all fields of surgery. Even in thyroidectomies and parathyroidectomies, the emphasis on positive volume-outcome relationships is believed. It led us to an evaluation of volume activity's impact in terms of quality of care. A systematic narrative review was performed. According to the PRISMA criteria, we selected 87 paper and, after the study selection was performed, 22 studies were finally included in this review. All articles included were unanimous in attributing to activity volume of surgeons as well as centers a substantial importance. Some differences in outcomes between these investigated categories ha…

Biologic Response of Inguinal Hernia Prosthetics: A Comparative Study of Conventional Static Meshes Versus 3D Dynamic Implants

2015

Despite improvements in prosthetics and surgi- cal techniques, the rate of complications following inguinal hernia repair remains high. Among these, discomfort and chronic pain have become a source of increasing concern among surgeons. Poor quality of tissue ingrowth, such as thin scar plates or shrinking scars—typical results with con- ventional static implants and plugs—may contribute to these adverse events. Recently, a new type of 3D dynami- cally responsive implant was introduced to the market. This device, designed to be placed fixation-free, seems to induce ingrowth of viable and structured tissue instead of regressive fibrotic scarring. To elucidate the differences in biologic respo…

Laparoscopic treatment of a large pedunculated hemangioma of the liver: a case report

2016

Hepatic hemangiomas are the most common benign tumors of the liver, often asymptomatic and discovered incidentally. A 62-year-old woman was referred to our Institution under the suspicion of having an 8 cm-sized GIST. Due to the atypical features of the lesion on TC scan, a biopsy was performed. We report the case of pedunculated hepatic hemangioma with the aim to discuss the diagnostic approach, the possible causes of misdiagnosis and the opportunity of the laparoscopic approach.

Bone morphogenetic protein 4 induces differentiation of colorectal cancer stem cells and increases their response to chemotherapy in mice.

2010

BACKGROUND & AIMS: The limited clinical response observed in many patients with colorectal cancer may be related to the presence of chemoresistant colorectal can- cer stem cells (CRC-SCs). Bone morphogenetic protein 4 (BMP4) promotes the differentiation of normal colonic stem cells. We investigated whether BMP4 might be used to induce differentiation of CRC-SCs and for therapeutic purposes. METHODS: CRC-SCs were isolated from 25 tumor samples based on expression of CD133 or using a selection culture medium. BMP4 expression and activity on CRC-SCs were evaluated in vitro; progeny of the stem cells were evaluated by immunofluorescence, immuno- blot, and flow cytometry analyses. The potential …

CD44v6 is a marker of constitutive and reprogrammed cancer stem cells driving colon cancer metastasis.

2014

SummaryCancer stem cells drive tumor formation and metastasis, but how they acquire metastatic traits is not well understood. Here, we show that all colorectal cancer stem cells (CR-CSCs) express CD44v6, which is required for their migration and generation of metastatic tumors. CD44v6 expression is low in primary tumors but demarcated clonogenic CR-CSC populations. Cytokines hepatocyte growth factor (HGF), osteopontin (OPN), and stromal-derived factor 1α (SDF-1), secreted from tumor associated cells, increase CD44v6 expression in CR-CSCs by activating the Wnt/β-catenin pathway, which promotes migration and metastasis. CD44v6− progenitor cells do not give rise to metastatic lesions but, when…

Surgical Emergencies in Crohn’s Disease

2015

Crohn’s disease, as a chronic inflammatory disease of unknown etiology that can affect any part of the alimentary canal from the mouth to the anus, has a highly variable course and a very unpredictable evolution. Even surgery does not cure CD, it has however a relevant role in its treatment in combination to medical therapy during the large course of the disease; indeed almost each patient is submitted to a surgical intervention during his life. Nowadays, surgery is considered the last treatment to use whenever medical therapy is insufficient to control symptoms; this choice involves an intervention on more serious patients with more surgical complications. Surgery finds in the Crohn’s dise…

Nerve degeneration in inguinal hernia specimens

2011

BACKGROUND: The histological study of the herniated inguinal area is rare in the literature. This report is focused on the detection of structural changes of the nerves within tissues bordering the inguinal hernia of cadavers. Their physiopathological consequences are hypothesized. MATERIALS AND METHODS: Primary inguinal hernia was diagnosed in 30 fresh cadavers. Tissue specimens from the inguinal region close to and around the hernia opening were excised for histological examination. A control of the data was achieved through tissue samples excised from equivalent sites of the inguinal region in 15 cadavers without hernia. RESULTS: The detected nerves in the inguinal area demonstrated path…

Achalasia Secondary to Submucosal Invasion by Poorly Differentiated Adenocarcinoma of the Cardia, Siewert II: Consideration on Preoperative Workup.

2014

Secondary achalasia due to submucosal invasion of cardia by gastric cancer is a rare condition. We report a case of pseudoachalasia, secondary to the involvement of gastroesophageal junction by poorly differentiated gastric cancer, initially mistaken as idiopathic form. We focus on the difficulty to establish differential diagnosis only on the basis of routine exams and we stress the necessity of “second level” instrumental exams; EUS in routine workup in selected patients should be considered. We support that routine workup based on history, clinical presentation, radiological and endoscopic findings, and certainly manometry could be insufficient for a correct differential diagnosis betwee…

Rectal bleeding and prolapse… not always benign diseases rather anal cancer. The importance of a correct decision making since primary care

2016

Rectal bleeding is very common in general population with a prevalence of 10-20 %. Primary care physicians have to stratify patients basing on urgency and on the colo-rectal cancer risk and to conduct a decision making for the correct management. We report a case of a 61-years-old woman, complaining rectal bleeding and an anal mass attended to their family doctor who does a visit but without a digital rectal examination and diagnosed a hemorrhoidal prolapse suggesting medical therapy. For the persistence of symptoms she comes to our service from emergency attention. Inspection and digital rectal examination revealed an anal mass. CT scan was performed showing a large anal mass involving hal…

Right diaphragmatic injury and lacerated liver during a penetrating abdominal trauma: case report and brief literature review

2014

Introduction: Diaphragmatic injuries are rare consequences of thoracoabdominal trauma and they often occur in association with multiorgan injuries. The diaphragm is a difficult anatomical structure to study with common imaging instruments due to its physiological movement. Thus, diaphragmatic injuries can often be misunderstood and diagnosed only during surgical procedures. Diagnostic delay results in a high rate of mortality. Methods: We report the management of a clinical case of a 45-old man who came to our observation with a stab wound in the right upper abdomen. The type or length of the knife used as it was extracted from the victim after the fight. CT imaging demonstrated a right hem…

Tumorigenic and metastatic activity of human thyroid cancer stem cells

2010

Abstract Thyroid carcinoma is the most common endocrine malignancy and the first cause of death among endocrine cancers. We show that the tumorigenic capacity in thyroid cancer is confined in a small subpopulation of stem-like cells with high aldehyde dehydrogenase (ALDHhigh) activity and unlimited replication potential. ALDHhigh cells can be expanded indefinitely in vitro as tumor spheres, which retain the tumorigenic potential upon delivery in immunocompromised mice. Orthotopic injection of minute numbers of thyroid cancer stem cells recapitulates the behavior of the parental tumor, including the aggressive metastatic features of undifferentiated thyroid carcinomas, which are sustained by…

Corrigendum to “Hiatal Hernia Repair with Gore Bio-A Tissue Reinforcement: Our Experience”

2015

Type I hiatal hernia is associated with gastroesophageal reflux disease (GERD) in 50-90% of cases. Several trials strongly support surgery as an effective alternative to medical therapy. Today, laparoscopic fundoplication is considered as the procedure of choice. However, primary laparoscopic hiatal hernia repair is associated with upto 42% recurrence rate. Mesh reinforcement of the crural closure decreases the recurrence but can lead to complications, above all nonabsorbable ones. We experiment a new totally absorbable mesh by Gore. Case. We present a case of a 65-year-old female patient with a 6-year classic history of GERD. Endoscopy revealed a large hiatal hernia and esophagitis. pH stu…

Surgical pathology and the diagnosis of invasive visceral yeast infection: two case reports and literature review

2013

Invasive mycoses are life-threatening opportunistic infections that have recently emerged as a cause of morbidity and mortality following general and gastrointestinal surgery. Candida species are the main fungal strains of gut flora. Gastrointestinal tract surgery might lead to mucosal disruption and cause Candida spp. to disseminate in the bloodstream. Here we report and discuss the peculiar clinical and morphological presentation of two cases of gastrointestinal Candida albicans lesions in patients who underwent abdominal surgery. Although in the majority of cases reported in the literature, diagnosis was made on the basis of microbiological criteria, we suggest that morphological feature…

Efficient Killing of Human Colon Cancer Stem Cells by γδ T Lymphocytes

2009

Abstract Colon cancer comprises a small population of cancer stem cells (CSC) that is responsible for tumor maintenance and resistant to cancer therapies, possibly allowing for tumor recapitulation once treatment stops. We previously demonstrated that such chemoresistance is mediated by autocrine production of IL-4 through the up-regulation of antiapoptotic proteins. Several innate and adaptive immune effector cells allow for the recognition and destruction of cancer precursors before they constitute the tumor mass. However, cellular immune-based therapies have not been experimented yet in the population of CSCs. Here, we show that the bisphosphonate zoledronate sensitizes colon CSCs to Vγ9…

2010

An important molecular target for metastatic CRC treatment is the epidermal growth factor receptor (EGFR). Many potential biomarkers predictive of response to anti-EGFR monoclonal antibodies (cetuximab and panitumumab) have been retrospectively evaluated, including EGFR activation markers and EGFR ligands activation markers. With regard to the "negative predictive factors" responsible for primary or intrinsic resistance to anti-EGFR antibodies a lot of data are now available. Among these, KRAS mutations have emerged as a major predictor of resistance to panitumumab or cetuximab in the clinical setting and several studies of patients receiving first and subsequent lines of treatment have sho…

Terminal or truncal ligation of the inferior thyroid artery during thyroidectomy? A prospective randomized trial.

2016

Abstract Introduction Thyroidectomy is a common procedure in general and endocrine surgery. The technique of ligation of inferior thyroid artery (ITA) has been invoked as a possible cause of appearance of postoperative hypocalcemia. Methods We performed a prospective randomized study involving 184 patients undergoing total thyroidectomy to evaluate the differences of truncal ligation versus distal ligation of ITA in terms of postoperative hypocalcemia, vocal fold palsy, voice and swallowing impairment. The patients were divided into group A (trunk ligation of ITA) and group B (terminal branches ligation of ITA). Results We evaluated postoperative PTH and calcemia (immediate, 6 and 12 months…

Colon Cancer Stem Cells Dictate Tumor Growth and Resist Cell Death by Production of Interleukin-4

2007

A novel paradigm in tumor biology suggests that cancer growth is driven by stem-like cells within a tumor. Here, we describe the identification and characterization of such cells from colon carcinomas using the stem cell marker CD133 that accounts around 2% of the cells in human colon cancer. The CD133(+) cells grow in vitro as undifferentiated tumor spheroids, and they are both necessary and sufficient to initiate tumor growth in immunodeficient mice. Xenografts resemble the original human tumor maintaining the rare subpopulation of tumorigenic CD133(+) cells. Further analysis revealed that the CD133(+) cells produce and utilize IL-4 to protect themselves from apoptosis. Consistently, trea…

Outpatient Treatment of Hemorrhoidal Disease: The Alternative Way to Treat Hemorrhoidal Disease in a Simple, Safe and Effective Manner.

2021

Background:: Hemorrhoidal disease is a widespread problem in healthy working patients. The traditional surgical approaches cause a loss of several working days related to the post-- operative course that is often painful. To avoid these problems while offering a symptoms resolution in patients with low degrees hemorrhoids, the non-surgical treatments are nowadays largely proposed in proctological clinics. Methods: We resume the recent literature on the issue to offer a practical and easy to use guide for clinicians. Results: Rubber band ligation, injection sclerotherapy and infrared coagulation are cost effective, safe and effective treatments for patients with II- and III-degree hemorrhoi…

Overexpression of cyclin D1 and interaction between p27Kip1 and tumour thickness predict lymph node metastases occurrence in lower lip squamous cell …

2005

We have attempted to identify those subgroups of patients most likely to develop lymph node metastases from squamous cell carcinoma of the lower lip (LLSSC). A total of 97 subjects, who did not undergo elective neck dissection, were recruited into the 60-month disease-free survival study. After univariate analysis, tumour size, histological grading, maximal thickness, perineural invasion and immunoreactivity to cyclin D1 and p27Kip1 proteins proved to be significant factors. Tests of the effect of interaction between p27Kip1 LI and tumour thickness yielded that the impact of tumour thickness on the risk of lymph node metastases was modified by the percentage of p27Kip1 positive cells. Subse…

Neuroendocrine tumor of the common bile duct: case report

2017

Neuroendocrine tumors (NET) are a very heterogeneous group of neoplasms; in recent years we have seen an increase in their incidence (3.65 /100.000/year). They can be associated with hereditary endocrine syndromes (MEN, Von Hippel Lindau); they can occur at any age and the incidence is slightly higher in men than women. The aetiology of the neuroendocrine tumors is unclear; in most cases, inflammation of the bile ducts may be the underlying cause and for this reason, the initial patient's evaluation should be focused on the different aspects concerning the oncological one and the possible sequelae of the biliary obstructions that can evolve in biliary sepsis. All neuroendocrine tumors have …

Three-dimensional (3D) versus two-dimensional (2D) laparoscopic adrenalectomy: A case-control study

2016

Abstract Introduction Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of two-dimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Tree-dimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy. Methods We report our experience with use of 3D vision system for laparoscopic adrenalectomy. Between January 2009 and March 2015 we performed a total of 52 laparoscopic adrenalectomies. In this case-control study we considered 13 laparoscopic adrenalectomies performed with three-dimensional (3D) vi…

Analysis of the Thymidylate Synthase Gene Structure in Colorectal Cancer Patients and Its Possible Relation with the 5-Fluorouracil Drug Response

2009

Thymidylate synthase (TS) catalyzes methylation of dUMP to dTMP and it is the target for the 5-Fluorouracil (5-FU) activity. Barbour et al. showed that variant structural forms of TS in tumour cell lines confer resistance to fluoropyrimidines. We planned to perform the whole TS gene structure by means of sequencing techniques in human colorectal cancer (CRC) samples to try to identify the presence of any possible TS variant form that could be responsible of fluoropyrimidines drug resistance and of the worse prognosis. We performed the TS-DNA gene sequence in 68 CRC from patients of A, B, and C Dukes' stages and different histological grade, but we did not find any mutation in the TS-DNA str…

Innovation in endocrine surgery: robotic versus laparoscopic adrenalectomy. Meta-analysis and systematic literature review.

2017

Several studies in the last years demonstrated the better surgical outcome of laparoscopic approach to adrenal gland. Laparoscopic surgery is more difficult to learn and requires different psychomotor skills than open surgery, especially with regard to complex maneuvers requiring precision and dexterity. The development of robotic platform with three-dimensional vision and increased degrees of freedom of the surgical instruments has the aim to overcome these problems. We performed a systematic literature review with meta-analysis to evaluate preoperative data and surgical outcomes of robotic adrenalectomy compared with laparoscopic technique. In September 2016 we performed a systematic lite…

Endometrial cancer: Robotic versus Laparoscopic treatment. Preliminary report

2015

Laparoscopic approach is today the standard treatment for benign and malignant gynecological pathologies. To traditional laparoscopic surgery in the last 10 years we can add the possibility to use a robotic platform. The adoption of this system allows undoubted advantages as the three-dimensional vision, the absence of the physiological tremor with enhanced ergonomics and possibility of using articulable tools. In this study we analyzed the results of 18 patients with endometrial cancer (Stage I) treated with robotic approach. The results were compared with a selected sample of 26 patients, with the same characteristics, treated with traditional laparoscopic approach in the same period by t…

Adrenal gunshot wound: Laparoscopic approach. Report of a case

2013

introduction: Although there is no debate that patients with peritonitis or hemodynamic instability should undergo urgent laparotomy after penetrating abdominal injury, it is also clear that certain stable patients may be managed without operation. Controversy persists regarding use of laparoscopy. PRESENTATION OF CASE: We report a case of gunshot wounds with bullet in left adrenal gland and perirenal subcapsular hematoma. The patients had no signs of peritonitis but in the observation period we noted a significative blood loss, so we performed an exploratory laparoscopy. DISCUSSION: We found the bullet in adrenal parenchyma. The postoperative period was regular and the patient was discharg…

Bowel wall thickening: inquire or not inquire? Our guidelines

2018

Introduction Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed. Patients and methods We conducted a retrospective study on data collected from May 2016 to June 2017. We selected 40 adult patients, admitted in Emergency Department with "abdominal pain" and undergone a…

Gemcitabine and oxaliplatin combination chemotherapy in advanced biliary tract cancers

2006

Background Biliary tract cancers are uncommon tumors with a poor prognosis and most patients present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, with poor response rates and a median survival of less than 6 months. Oxaliplatin and gemcitabine have shown an interesting activity as single agents in this group of patients. Patients and methods We carried out a multicenter phase II study to evaluate the efficacy and safety of combined oxaliplatin and gemcitabine in locally advanced and metastatic biliary tract carcinoma. The schedule of chemotherapy included oxaliplatin 100 mg/m2 on day 1 and gemcitabine 1000 mg/m2 on days 1 and 8, every 21…

Fully robotic left hepatectomy for malignant tumor: technique and initial results

2018

Robotic liver surgery has been considered as a unique opportunity to overcome the traditional limitations of laparoscopy; thus, it can potentially extend the indications of minimally invasive liver surgery. From April 2015 to May 2017, 35 patients underwent fully robotic left hepatectomy. The mean operative time was 315 min (200-445 min) and the mean estimated blood loss was 245 ml (125-628 ml). Pringle maneuver was required in six cases. Cancer was the indication for surgery in all patients (14 liver metastases, 18 hepatocellular carcinomas and 3 cholangiocarcinomas). There were one to four lesions in a patient and the mean lesion size was 39.2 mm (15-85 mm). The average length of hospital…

A method of reconstruction after pancreaticoduodenectomy for pancreatic malignancies in very young children: Two cases reports

2016

Abstract Pancreatic tumors are very rare diseases in very young children. Most information about those diseases in children was published in cases reports. Due to the rare nature of pancreatic tumors in children, there remains the absence of diagnostic algorithms, clear radiographic and morphological assessments as well as evidence based best treatment options. Because of the young age of patients and the rare occurrence of pancreatic neoplasms, tumor detection remains poor. For malignancies affecting the head of the pancreas the only possibility for achieving clear surgical margins is performing a pancreaticoduodenectomy (PD). We describe two cases of diagnostic and treatment of pancreatic…

Non-functioning parathyroid cystic tumour: malignant or not? Report of a case

2017

Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found. It presented caudal extent on anterior mediastinum causing compression of the left lateral wall of the trachea. The preoperative calcemia was into the normal ran…

Large retroperitoneal abscess extended to the inferior right limb secondary to a perforated ileal Crohn’s disease: the importance of the multidiscipl…

2016

The typical complications of Crohn's disease concerns small and large bowel. The full thickness inflammation of the intestinal wall develops in strictures, fistulas and abdominal abscesses. Nowadays the most accepted therapeutic for intra-abdominal abscess option is antibiotic therapy and, in case of need, percutaneous drainage of the abscess. If the abscess passes through the pelvic foramen the abscess can involve the inferior limbs. We report a case a perforation of terminal ileum in Crohn's disease complicated by a large abscess of the right iliac fossa reaching the spaces between the anterior lateral muscles of the right thigh as far as the anterior lateral pre-tibial region.

Acute appendicitis: should the laparoscopic approach be proposed as the gold standard? Six-year experience in an Emergency Surgery Unit

2016

Acute appendicitis is common in an Emergency Surgery Unit. Although the laparoscopic approach is a method accepted for its treatment, no strong data are available for determining how many procedures must an experienced surgeon carry out for obtaining all the advantages of this technique and if this approach can become the gold standard in the activity of a general emergency unit with senior surgeons variously skilled on the basic laparoscopy. 142 patients that underwent appendectomy (90 laparoscopic, 52 conventional) for acute appendicitis were enrolled in this institutional retrospective cohort study. The surgeons were classified with a descriptor-based grading and divided in two groups re…

Current advances in γδ T cell-based tumor immunotherapy

2017

γδ T cells are a minor population (~5%) of CD3 T cells in the peripheral blood, but abound in other anatomic sites such as the intestine or the skin. There are two major subsets of γδ T cells: those that express Vd1 gene, paired with different Vγ elements, abound in the intestine and the skin, and recognize the major histocompatibility complex (MHC) class I-related molecules such as MHC class I-related molecule A, MHC class I-related molecule B, and UL16-binding protein expressed on many stressed and tumor cells. Conversely, γδ T cells expressing the Vδ2 gene paired with the Vγ9 chain are the predominant (50-90%) γδ T cell population in the peripheral blood and recognize phosphoant…

Laparoscopic management of adrenal tumors: A four-year experience in a single center

2014

AIM: Today laparoscopy is considered the first choice treatment of many adrenal tumors, although its use is still controversial for large adrenal masses and incidentally found adrenal cortical carcinoma. METHODS: From January 2009 to February 2014 we performed 42 lateral transperitoneal laparoscopic adrenalectomies. The indications for surgery were non-functioning adenoma larger than 4 cm or rapid growth and hormone-secreting tumor.

Diagnostic and Therapeutic Role of Endoscopy in Crohn’s Disease

2015

Endoscopy plays a very important role in the management of Crohn’s disease (CD). It is an extremely important diagnostic tool in the period of symptoms onset, allowing the evaluation of the activity and of the extent of the disease; moreover, it is very useful in follow-up giving an evaluation of the response to the medical therapy, a detection of recurrences following surgery, and providing an oncological screening. Several procedures like traditional colonoscopy, single- and double-balloon enteroscopy, endocapsule examination, and endoscopic ultrasound are today available. CD can be diagnosed with endoscopy by a skilled gastroenterologist in the setting of a suggestive clinical presentati…

Monoclonal antibodies and antibody fragments: state of the art and future perspectives in the treatment of non-haematological tumors

The antibodies approved for use in clinical practice for the treatment of non-haematological tumors and those antibodies still being developed in this setting are briefly described. The types of antibody fragments are also reported. Expert opinion: Monoclonal antibodies w…

Suppressor of cytokine signaling 3 sensitizes anaplastic thyroid cancer to standard chemotherapy

2009

We previously showed that cancer cells from papillary, follicular, and anaplastic thyroid carcinomas produce interleukin-4 and interleukin-10, which counteract the cytotoxic activity of conventional chemotherapy through the up-regulation of antiapoptotic molecules. Here, we identify Janus kinase/signal transducers and activators of transcription (STAT) and phosphatidyl inositol 3-kinase (PI3K)/AKT as the down-stream pathways through which these cytokines confer resistance to cell death in thyroid cancer. We found that the absence of suppressors of cytokine signaling (SOCS) molecules allows the propagation of the survival signaling. Exogenous expression of SOCS1, SOCS3, and SOCS5 in the high…

Skin-nipple-sparing mastectomy: The first approach in primary myxoid chondrosarcoma of the breast

2017

Abstract The primary mammary chondrosarcoma corresponds to less than 0,5% of the mammary malignancies. For the period ranging from 1967 to 2014, only 18 cases were reported in the literature. A 41 year old woman found a hard nodule on her external right superior quadrant/axillary prolongation through breast self-examination. The vacuum-assisted core biopsy (VACB) revealed “high grade extra-skeletal myxoid chondrosarcoma”. A skin-nipple-sparing mastectomy with the insertion of a mammary expander was performed. A protocol of adjuvant radiotherapy was also indicated. Until 2013, the gold standard was the radical mastectomy. By 2014, there were two cases of conservative approach to quadrantecto…

Oligo-antigenic diet in the treatment of chronic anal fissures. Evidence for a relationship between food hypersensitivity and anal fissures.

2013

Abstract OBJECTIVES: Patients with chronic constipation due to food hypersensitivity (FH) had an elevated anal sphincter resting pressure. No studies have investigated a possible role of FH in anal fissures (AFs). We aimed to evaluate (1) the effectiveness of diet in curing AFs and to evaluate (2) the clinical effects of a double-blind placebo-controlled (DBPC) challenge, using cow's milk protein or wheat. METHODS: One hundred and sixty-one patients with AFs were randomized to receive a "true-elimination diet" or a "sham-elimination diet" for 8 weeks; both groups also received topical nifedipine and lidocaine. Sixty patients who were cured with the "true-elimination diet" underwent DBPC cha…

Aminobisphosphonates as New Weapons for &amp;#947; &amp;#948; T Cell-Based Immunotherapy of Cancer

2008

Several observations in mice and in humans have collectively laid the foundation for examining the potential of γ δ T cells to exert tumor immunotherapy. Human γ δ T cells can be activated in a non-MHC dependent fashion either by low molecular mass phosphoantigens, or by agents that provoke the accumulation of endogenous pyrophosphates such as isopentenylpyrophosphate. Among the latter, aminobisphosphonates are well-established in the clinic, and extensive data are available on the compounds antiangiogenic, antiosteolytic and pro-apoptotic properties. In this review we discuss on the possibility that the intentional activation of γ δ T cells in vivo by aminobisphosphonates may represent a p…

Prosthetic strap system for simplified ventral hernia repair. Its results in a porcine experimental model.

2010

Abstract: Introduction Aiming to achieve a simplified ventral hernia repair, a proprietary shaped mesh was experimentally tested in the porcine model. The mesh is structured with a large central body and radiating straps. The friction of the straps passing through the tissues are hypothesized to be adequate to maintain the mesh in place during tissue ingrowth, avoiding classic point fixation while ensuring a wide coverage of the abdomen. Methods The mesh, having 6 radial straps, was placed using a sublay preperitoneal technique in 4 pigs. All straps were passed laterally through the abdominal wall and exteriorized from the skin. The straps were trimmed at the level of the skin, allowing the…

Update in laparoscopic approach to acute mesenteric ischemia

2016

AMI is an uncommon but serious disease often associated with a bad prognosis, associated with occlusion of Superior Mesenteric Artery (SMA) for embolism or thrombosis (67.2 %), mesenteric venous thrombosis (15.7 %), and non-occlusive mesenteric ischemia (15.4 %). Clinical markers are often aspecific and symptoms low suggestive. The gold standard for the diagnosis is multidetector CT Angiography (CTA) with sensibility of 93.3 % and specificity of 95.9 %. Abdominal exploration could be useful to confirm cases of AMI without signs of SMA occlusion at CTA. Few reports have been found on the diagnostic role of Exploratory Laparoscopy. To increase the sensibility of laparoscopy in the diagnosis o…

Dynamic inguinal hernia repair with a 3d fixation-free and motion-compliant implant: a clinical study.

2014

Static solutions for highly motile structures such as the groin seem to represent a procedural incongruence. Another important issue in prosthetic hernia repair is related to the poor quality of tissue ingrowth within conventional flat meshes and plugs. These are all static, passive devices, and thus do not move in synchrony with the natural movements of the groin. In the literature there is a clear understanding of how conventional prostheses used for inguinal hernia repair are incorporated by rigid fibrotic tissue. The term "scar plate" well emphasizes this occurrence. The ingrowth of this kind of stiff fibrotic scar leads to mesh shrinkage and to the reduction of the mesh surface area. T…

Could a variant structural form of thymidylate synthase gene of metastatic colorectal cancer patients be related with the poor response to 5 Fu treat…

2008

Background: Thymidylate synthase (TS) catalyzes methylation of dUMP to dTMP and is the target of 5-fluorouracil (5-Fu). TS levels vary considerably among tumors and the response to 5-FU is influenced by the intratumoral activity of the enzyme, with high levels generally being associated with a poor response. Response to 5-FU also depends on TS structure and some researchers showed that variant structural forms of TS in tumour cell lines confer resistance to fluoropyrimidines so the aim our study is to analyze the whole coding regions of the TS gene to evaluate a possible mechanism of 5 Fu resistance. Materials and Methods: We performed the TS-DNA gene sequence in 68 colorectal cancer (CRC) …

Analysis of the Thymidylate Synthase Gene Structure in Colorectal Cancer Patients and lts Possible Relation with the S-Fluorouracil Drug Response

2010

Thymidylate synthase (TS) catalyzes methylation of dUMP to dTMP and it is the target for the 5-Fluorouracil (5-FU) activity*. Barbour et al. showed that variant structural forms of TS in tumour cell lines confer resistance to fluoropyrimidines. We planned to perform the whole TS gene structure by means of sequencing techniques in human colorectal cancer (CRC) san-rples to try to identify the presence of any possible TS variant form that could be responsible of fluoropyrimidines drug resistance and of the worse prognosis. We performed the TS-DNA gene sequence in 68 CRC from patients of A, B, and C Dukes' stages and different histological grade, but we did not find any mutation in the TS-DNA …

Bisphosphonate-associated femoral fracture: implication for management

2008

Studies carried out on individuals being treated long term with bisphosphonates have provoked considerable interest and perplexity about the effect that these drugs have on bone turnover in the long run. In fact the experiences reported by numerous researchers tend to highlight how treatment with high doses of bisphosphonates over many years, of individuals with osteoporosis complicated by or secondary to neoplastic pathologies, causes a suppression of bone turnover that over time predisposes the bone to the accumulation of micro damage that can then result in complicated fractures, as in the case described here.

Galectin-3 immunodetection for improving the performance of conventional thyroid cytology: preliminay results

2008

Introduction: Most of differentiated thyroid carcinomas should be easily revealed by fine-needle aspiration cytology but sometimes preoperative diagnosis is doubtful. Galactin-3 is a carbohydrate –binding protein with affinity for beta-galactosides that plays a significant role in cell-cell and cell matrix adhesion, growth, neoplastic transformation and metastasis. Moreover, galectin-3 immunodetection is related to follicular thyroid malignancies. Our aim is to test Galectin-3 as potential preoperative marker for follicular and papillary carcinomas. Methods: Expression of galectin -3 was tested by fluorescence staining on 40 fresh cytological thyroid samples obtained preoperatively; the sam…

Short stay thyroid surgery: a personal experience

2008

Introduction: In spite of a low incidence of complications during thyroidectomy, there is a widespread tendency to extend hospitalization at least until postoperative second day. The need of a rebalancing between costs and profits had led us to revise the hospitalization’s duration. Methods: We reviewed our early experience (129 patients candidated to total thyroidectomy as ordinary hospitalization from 2001 to 2002) identifying the causes of hospitalization’s delay both preoperatively and in discharge. We excluded from our analysis re-operations, substernal goitre requiring sternotomy, carcinomas needing a systematic lymphadenectomy and some cases of internal medical interest. Between June…

Dynamic autostatic implant for inguinal hernia repair. Early results in an explorative cohort of patients

2010

Acknowledging the need to further improve outcomes and reduce complications in inguinal hernia repair, our group has been developing new surgical implants for this condition. Our primary considerations are to reduce complications associated with invasive fixation, and improve the quality of the tissue ingrowth within the implant. We have developed a new type of 3D dynamic, self retaining implant to achieve these effects. This newly designed implant was previously experimentally tested in porcine model, showing excellent outcomes. Above all, the results concerning the quality of tissue ingrowth and the nearby absence of shrinkage in the long term were excellent. In this report we describe th…

Physiopathology of hernia disease

2012

The genesis of inguinal hernia still represents a dilemma. Deryite innovation in surgical matenals and techniques, no care has lrccn eler concerning the etiology of hernia. Following a specific Erlnù tissue samples were excised in 30 fresh male cadavers with iÉr.l lsnias, from structures close to the hemia orifice. for histological study. 15 cadavers without hernia served as conffol. The tissue excised demonstrated several histological changes. Among these, fibrohyaline degeneration and fatty dystrophy of the myocytes. Besides limpho-histiocytic and plasmacellular clusters, we found also vein fibrosis and congestion. The arterial structrres showed thicken- ing of the media due to Lyperplade…

COLONIC LOCALIZATION OF MYXOID LIPOSARCOMA: CASE REPORT

2008

INTRODUCTION: myxoid liposarcoma approximately constitutes 20% of all mesenchymal malignancies preferably occurring in adults with prevalent localization in arts even if there are rare intra-abdominal locations: only 3 cases reported in the literature. We present a case of myxoid liposarcoma with colic localization outlining a diagnostic and therapeutic procedure through a literature’s review. CASE REPORT: We observed a 37 year-old man in January 2007 because of colic pain in the middle abdomen, dyspepsia and constipation. The CT with contrast agent showed a capsulated solid mass with net margins, lobules and adipose tissue component compressing and displacing small bowel. After incision we…

Acute appendicitis and endometriosis: Retrospective analysis in emergency setting

2013

Introduction. The aim of this study is to evaluate the incidence of appendiceal and pelvic endometriosis in a population with diagnosis of acute appendicitis in an emergency setting. Materials and methods. We carried out a retrospective study in the period between January 2010 and October 2013. We performed 429 appendectomy including 233 in female subjects (54.3%). In all patients of childbearing age, we did β-hCG urine test to rule out the presence of an extra-uterine pregnancy. Results. 127 of 233 patients received a laparoscopic approach (54.5%). The median age was 29 years-old (range 17-68). The diagnosis of appendiceal and/or pelvic endometriosis was performed in 10 patients (4.3%): 9 …

Fine-Needle Aspiration (FNAB) Molecular Analysis for the Diagnosis of Papillary Thyroid Carcinoma through BRAFv600E mutation and RET/PTC rearrangement

2007

Objective: To evaluate BRAFV600E mutation on consecutive fine-needle aspiration biopsy (FNAB) specimens in order to assess FNAB’s usefulness in preoperative papillary thyroid carcinoma (PTC) diagnosis with the contemporaneous analysis of RET=PTC1 and RET=PTC3 rearrangements obtained from ex vivo thyroid nodules. Design: Thyroid FNABs from 156 subjects with nodules and 49 corresponding surgical samples were examined for the presence of BRAF mutation by real-time allele-specific polymerase chain reaction, confirmed with the use of a laser pressure catapulting system. Samples were also examined for RET=PTC rearrangements. The results were compared with the cytological diagnosis and histopathol…

Efficacy of fibrin sealant in thyroid surgery. Is drainage still necessary?

2019

The routinely use of drains in thyroid surgery is a traditional and well-defined method, even if there is no clear evidence of significant improvement in patients outcomes. Aim of our study is to define the feasibility, safety and cost- effectiveness of fibrin sealant in total thyroidectomy in order to overcome the use of drains.We enrolled 262 patients (45 men and 217 women, mean age 54.7 yrs) undergone total thyroidectomy in University Hospital of Palermo (Italy), between July 2015 and October 2017. We randomized patients into group A (drain) and group B (no drain, fibrin sealant application).We registered statistical difference between the two groups in mean operative time, visual analog…

La Ricerca in Chirurgia

2008

Dalla nascita della chirurgia scientifica durante la metà del ‘700, anni in cui J. Hunter ricorreva alla corruzione di un becchino per studiare il caso del gigante Charles Byrne ad oggi, la pratica medico-chirurgica è molto cambiata; si affida, infatti, sempre di più alle evidenze basate sulla costruzione, sull’esecuzione e sull’analisi degli studi clinici sperimentali. Il CD multimediale,rivolto prevalentemente ai giovani (studenti, medici, specializzandi) ha lo scopo di guidarli nell'affascinante mondo della ricerca in ambito chirurgico.
