Giant hepatic hydatid cyst as a cause of small bowel obstruction.

2006

Today, giant hydatid cysts are fairly rare even in endemic areas. We describe a case of an extremely large hydatid cyst of the liver that was causing massive compression of the neighboring organs, giving rise to a subocclusive syndrome of the intestine. After considering the various approaches available for the treatment of this disease, it was decided that radical surgery was still the best therapeutic choice, especially when extremely large cysts are involved. In particular, in clinical situations where it is difficult to perform radical surgical procedures, less aggressive surgery followed by drug treatment should be the treatment of choice.

Imaging findings of liver resection using a bipolar radiofrequency electrosurgical device—Initial observations

2010

Abstract Objective To assess contrast-enhanced US (CEUS), computed tomography (CT) and magnetic resonance (MR) imaging findings and serial changes of the treated area at follow-up in patients who underwent liver resection using a bipolar radiofrequency electrosurgical device. Methods Imaging findings of 27 patients with resected hepatocellular carcinomas (HCCs) ( n  = 24) and metastases ( n  = 3) (mean size: 2.6 cm), were retrospectively evaluated. Two readers assessed: the (a) presence, (b) thickness, (c) shape and (d) echogenicity (CEUS)/attenuation (CT)/signal intensity (MR imaging) at coagulated site and the (e) presence of residual tumor of the bipolar radiofrequency electrosurgical de…

Affezioni benigne della tiroide: indicazioni al trattamento chirurgico ed attuale ruolo della tiroidectomia totale

2003

Total thyroidectomy is the most popular surgical option in a wide range of indications for the treatment of benign disease of the thyroid. The preference for the procedure derives from a long period of observation and clinical experience dating as far back as the early 'seventies and confirms its safety and efficiency. Nevertheless, many doubts still exist as to the indications in the context of benign thyroid disease, as well as the incidence and seriousness of the complications which, though not frequent, are often invalidating. On the basis of the experience gained over the period from January 1994 to November 2002 in 697 patients undergoing surgery for benign disease of the thyroid, the…

Hepatocellular carcinoma: comparison of two different periods at the same center.

2010

Aims: To analyze the main etiological factors and some clinical characteristics of patients with HCC at diagnosis and to compare them with those we described ten years ago. Methods: 179 patients were included in Group 1, while 132 patients were included in Group 2. For all patients age, sex, serum markers of hepatitis B and C viruses, alcohol consumption, serum alpha feto-protein (AFP) levels and the main liver function parameters at HCC diagnosis were recorded. Results: Mean age was 66.0 years for Group 1 and 69.0 for Group 2 (P=0.005). HCV was responsible for 80.3% of HCC cases in Group 2 versus 72% in Group 1 (P=0.005). HBV alone and co-infection of HCV+HBV decreased, but not significant…

Minor hepatic resection using heat coagulative necrosis

2009

Intra- and postoperative bleeding represents an extremely serious and frequent complication of hepatic surgery. In this study, we evaluated the effectiveness of a radiofrequency (RF) device using heat to cause coagulative necrosis of the hepatic parenchyma to control hemostasis in minor hepatic resection. Between December 2005 and November 2007, a study was conducted of 21 patients undergoing 22 hepatic resections with the RF-assisted technique. Sixteen of these were affected by hepatocellular carcinoma and five had liver metastases from colorectal cancer. Intraoperative blood loss, the need for blood transfusion, the complication rates, operating times, and the duration of postoperative h…

La termoablazione nel trattamento delle neoplasie epatiche primitive e secondarie

2004

Radiofrequency thermoablation is a locoregional procedure based on the use of electromagnetic waves that induce movement and consequently the production of heat. This is the basis for the coagulative necrosis produced in the tissues. The method, experimented with and developed in the '90s, is today extensively used in the treatment of focal hepatic lesions, both primary and secondary. The factors that condition the procedure are related essentially to the characteristics of the tumours and to the possibility of obtaining a predictable area of necrosis that guarantees the radicality of the treatment. As regards primary neoplasms, it should be stressed that the treatment for hepatocellular ca…

Frequent Alteration of the Yin Yang 1/Raf-1 Kinase Inhibitory Protein Ratio in Hepatocellular Carcinoma

2011

The transcription factor Yin Yang 1 (YY1) can favor several aspects of tumorigenesis. In turn, Raf-1 Kinase Inhibitor Protein (RKIP) inhibits the oncogenic activities of MAPK and NF-κB pathways and promotes drug-induced apoptosis. Mutual influences between YY1 and RKIP may exist, and there are already separate evidences that relevant increases in YY1 and reductions in RKIP occur in hepatocellular carcinoma (HCC). However, the levels of the two factors have never been concomitantly examined in HCC. We evaluated by RT-PCR the mRNA levels of YY1, YY1AP, RKIP, and survivin in 35 clinical HCCs (91% HCV-related), in their adjacent cirrhotic tissues and in 6 healthy livers. Immunohistochemical ana…

Gastrointestinal stromal tumors (GISTs): Focus on histopathological diagnosis and biomolecular features

2007

Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract that are believed to originate from a neoplastic transformation of the intestinal pacemaker cells (interstitial cells of Cajal) normally found in the bowel wall or their precursors. Although the microscopic features have been known for a long time, the defining characteristic of GIST is the presence of the cell-surface antigen CD117 (KIT), which is demonstrated by immunohistochemistry. KIT, which is a growth factor transmembrane receptor, is the product of the proto-oncogene c-kit (chromosome 4). Surgical removal remains the only curative treatment for patients with GISTs. Tumor size, mitotic index,…

Combined hepatectomy and radiofrequency ablation for multifocal hepatocellular carcinoma: a case report

2009

Introduction: At the present time, the best possible choice for the local management of a multifocal hepatocellular carcinoma (HCC) developing on liver cirrhosis is multimodal treatment of the disease. Combined approach based on simultaneous radiofrequency ablation (RFA) together with limited surgical resection represents a valid choice of treatment. Case presentation: A 75-year-old white female patient affected of HCV-associated cirrhosis in BChild-Pugh’s functional class A5, developed a bifocal HCC. The patient had undergone a limited surgical resection together with simultaneous RFA, without intraoperative and postoperative surgical complications. At 36 months after surgery, still shows …

I tumori della mammella e/o dell’ovaio di tipo eredofamiliare: strategie di prevenzione nelle donne ad alto rischio

2009

Numerosi fattori sono stati coinvolti nell’insorgenza del carcinoma mammario e dell’ovaio tra cui l’età, fattori ormonali e riproduttivi come l’età e il numero di gravidanze e l’utilizzo di contraccettivi orali e, in minor misura, fattori ambientali e stili di vita. Le possibilità per la gestione clinica delle pazienti considerate ad alto rischio di sviluppare carcinoma della mammella e/o dell’ovaio includono chirurgia profilattica (es. mastectomia bilaterale profilattica o ovarosalpingectomia bilaterale), chemioprevenzione (principalmente tamoxifene e raloxifene ma anche, più recentemente, inibitori dell’aromatasi nelle donne ad alto rischio in postmenopausa), cambiamenti nelle abitudini d…

Methods  We included 406 consecutive patients with cirrhosis and HCC. Seventy-eight per cent of patients had hepatitis C. Independent predictors of survival were identified using the Cox model. Results  One-hundred and seventy-eight patients were treated, while 228 were untreated. The observed mortality was 60.1% in treated p…

Incidence of new foci of hepatocellular carcinoma after radiofrequency ablation: role of multidetector CT

2012

Purpose. The authors sought to assess the incidence of new foci of hepatocellular carcinoma (HCC) using multidetector computed tomography (MDCT) in patients treated with radiofrequency ablation (RFA). Materials and methods. Two readers retrospectively reviewed by consensus the follow-up MDCT studies of 125 patients (88 men and 37 women; mean age 68 years) with 141 HCCs (size 1–5.2 cm; mean 2.2 cm) treated with RFA. MDCT follow-up was performed at 1 and 3 months and every 6–12 months thereafter. Reviewers assessed: (1) the presence of new HCC foci in the same liver segment or in a different segment; (2) complete or incomplete tumor ablation; (3) tumour progression. Results. A total of 113 ne…

Minor hepatic resection for hepatocellular carcinoma in cirrhotic patients: Kelly clamp crushing resection versus heat coagulative necrosis with bipo…

2011

Hemorrhage and postoperative liver insufficiency are frequent and serious complications of hepatic resection in cirrhotic patients. The aim of this study was to assess retrospectively whether the surgical techniques using Kelly clamp crushing resection or heat coagulative necrosis with a bipolar radiofrequency device can reduce the incidence of the above complications and an eventual recurrence of neoplasia on the liver slice. We retrospectively reviewed the results of 35 patients who had undergone resection for monofocal hepatocellular carcinoma at our center. Thirteen patients (Group A) had undergone liver resection with Kelly clamp crushing resection, 22 patients (Group B) had had liver…

Seeding after radiofrequency ablation of hepatocellular carcinoma in patients with cirrhosis: a prospective study.

2008

Abstract Background Neoplastic seeding of hepatocellular carcinoma may arise after radiofrequency ablation. Aims In order to clarify the real risk of seeding, we observed a prospective cohort of patients undergoing radiofrequency ablation. Methods Ninety-three (22.9%) out of 406 consecutive patients with hepatocellular carcinoma superimposed to cirrhosis diagnosed at our Liver Unit (2000–2005) were selected for radiofrequency ablation according to the Barcelona 2000 EASL guidelines. Seventy-one patients were treated by a percutaneous approach and 22 at laparotomy. After radiofrequency ablation ultrasound scan was repeated every 3 months and spiral-computed tomography every 6 months. Results…

Insufficienza renale acuta in paziente con carcinoma epatocellulare sottoposto a chemioembolizzazione transarteriosa

2007

Transarterial chemoembolization (TACE) is included among the wide therapeutic tools for the treatment of hepatocellular carcinoma (HCC), tumour with high frequency and malignancy. The approach is invasive and, beyond the discomfort for the patient, it is charged by a number of side effects and complications. In this study we report the case of renal acute failure of hypovolemic origin, as a consequence of a TACE in a patient suffering from HCC, occurred after one week of intervention. The different possible mechanisms involved in the pathogenesis of this complication are discussed.

LigaSure in total thyroidectomy.

2008

PURPOSE: LigaSure is a bipolar diathermy system, which achieves vessel sealing with reduced thermal spread. The device has been used successfully in abdominal operations and because of its features, it has been applied recently in thyroid surgery to minimize the risk of complications such as laryngeal nerve palsy and hypocalcemia, and also to reduce the operating time. METHODS: Between June and December 2005, we performed total thyroidectomy for various disorders in 105 patients. We used the LigaSure diathermy system in 53 patients and traditional hemostatic procedures in the other 52. We evaluated the demographic features, histopathological diagnosis, operating times, and relevant postoper…

Hashimoto Thyroiditis Coexistent with Papillary Thyroid Carcinoma

2005

Several studies report a higher rate of papillary thyroid carcinomas (PTC) in patients with Hashimoto thyroiditis (HT), indicating a possible correlation between the two diseases. We studied a group of 89 subjects undergoing surgery for thyroid carcinomas compared with a control group of 89 subjects operated on for normofunctioning goiter, and a second group of 47 patients undergoing total thyroidectomy for HT. Association with HT was found in 19 of the 71 PTC subjects (26.7%) and in 8 goiter patients (8.9%), which was a significant difference ( P < 0.02). Thirteen of the HT patients, mostly with the nodular form, showed coexistent PTC (27.6%). HT and PTC coexisted in several morphologi…

Cyclooxygenase-2 expression in chronic liver disease and hepatocellular carcinoma: an immunohistochemical study

2009

UNLABELLED Hepatocarcinogenesis is a multistep process characterized by hepatocyte inflammation, regeneration, and proliferation. These changes are believed to depend on the aberrant expression of various tumor suppressor genes, oncogenes and growth factors. Several studies have shown the involvement of cyclooxygenase-2 (COX-2), the inducible isoform of the enzymes that catalyze prostaglandin synthesis in various aspects of carcinogenesis. COX-2 has been described as being overexpressed in hepatocellular carcinoma (HCC) patients. Using immunohistochemistry, we studied COX-2 expression in different chronic liver diseases (CLD) including nonalcoholic steatohepatitis (NASH), chronic hepatitis …

La coagulazione elettrotermica bipolare (ligasure bipolar vessel sealing system) in chirurgia della tiroide

2003

Over the past few years different methods of achieving haemostasis in surgery have been developed. Among these methods, bipolar electrothermal coagulation carried out with the "LigaSure Bipolar Vessel Sealing System" has found numerous applications in some types of abdominal and pelvic surgery, especially when performed laparoscopically, where traditional methods of haemostasis sometimes prove more difficult to perform and are often unsafe. The authors also experimented with the use of electrothermal cautery in thyroid surgery, evaluating its efficacy in achieving haemostasis, as well as in reducing a number of complications such as hypoparathyroidism and recurrent palsy, which can be obtai…
