Endoscopic Resection of a Large Colonic Lipoma: Case Report and Review of Literature

2010

Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding and intussusception. We report the case of a 60-year-old man with a history of lower abdominal pain and pseudoobstructive symptoms. Colonoscopy revealed a large polypoid sessile lesion in the sigma. We used a standardized technique of polypectomy, preceded by submucosal injection of dilute 5 ml polygelin with epinephrine 1:10,000 solution, to fully resect large colonic lipomas. The lipoma size was 3.5 cm. No bleeding or perforation developed. Histology showed the polyp to be a submucosul lipoma. On follow-up, th…

PROSTATOSYMPHYSEAL FISTULA AFTER TRANSURETHRAL RESECTION OF THE PROSTATE

2001

The formation of a urethrosymphyseal fistula is a rare complication after transurethral resection of the prostate. It may develop secondary to previous radiation therapy of the pelvis. We describe a case of spontaneous fistula formation after transurethral resection of the prostate. CASE REPORT

Surgical and anatomical basis of autonomic nerve-preserving mesorectal excision for rectal cancer

2003

Adequate knowledge of the anatomy of the pelvis is a prerequisite to carry out a correct surgical technique in resection of rectal cancer. In this way, we can perform radical surgery, preserve the autonomic nerves and decrease local recurrence and urinary and sexual morbidity. The key to all this and the difference in results depends on a meticulous and detailed surgical technique.

T1HG Bladder Tumours: So Many Papers, Do We Need Them? Yes, We Do!

2009

“How many roads a man must walk on….” and how many papers we must read and write… to put down the final word on the appropriate management of high risk NMI-BC. Although it is more than 20 years that we take notice of promises on biological markers predictive of the behaviour of NMI-BC, till today we can only base our decisions on clinical and pathological data. Consequently, we need exchange of experiences and reports on the outcome of these patients. The aim of the treatment of T1 bladder tumours is to minimize mortality while assuring reduced morbidity and good quality of life. A conservative approach is, obviously, not applicable to all T1HG tumours. We need to identify unequivocal selec…

Is cell salvage safe in liver resection? A pilot study

2007

Abstract Study Objective To investigate the quality of cell salvaged (CS) blood in patients undergoing hemihepatectomy (study group) and compare it with CS-blood from aortic surgery (control group). Design Observational study. Setting Operating room in a university hospital. Measurements 6 patients undergoing hemihepatectomy or aortobifemoral bypass with intraoperative blood loss of more than 800 mL. Samples were drawn from the central venous catheter, from the reservoir of a CS recovery system, and from the processed blood in each patient to determine interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF), complement C3a, and the terminal complement complex C5b-9. Microbiological ana…

Brain mapping as helpful tool in brain glioma surgical treatment—Toward the “perfect surgery”?

2018

Gliomas are the most common primary malignant brain tumours in adults, representing nearly 80%, with poor prognosis in their high-grade forms. Several variables positively affect the prognosis of patients with high-grade glioma: young age, tumour location, radiological features, recurrence, and the opportunity to perform post-operative adjuvant therapy. Low-grade gliomas are slow-growing brain neoplasms of adolescence and young-adulthood, preferentially involving functional areas, particularly the eloquent ones. It has been demonstrated that early surgery and higher extent rate ensure overall longer survival time regardless of tumour grading, but nowadays, functional preservation that is as…

New Hope in Brain Glioma Surgery: The Role of Intraoperative Ultrasound. A Review

2018

Maximal safe resection represents the gold standard for surgery of malignant brain tumors. As regards gross-total resection, accurate localization and precise delineation of the tumor margins are required. Intraoperative diagnostic imaging (Intra-Operative Magnetic Resonance-IOMR, Intra-Operative Computed Tomography-IOCT, Intra-Operative Ultrasound-IOUS) and dyes (fluorescence) have become relevant in brain tumor surgery, allowing for a more radical and safer tumor resection. IOUS guidance for brain tumor surgery is accurate in distinguishing tumor from normal parenchyma, and it allows a real-time intraoperative visualization. We aim to evaluate the role of IOUS in gliomas surgery and to ou…

Endoscopic and surgical resection of T1a/T1b esophageal neoplasms: A systematic review

2013

AIM: To investigate potential therapeutic recommendations for endoscopic and surgical resection of T1a/T1b esophageal neoplasms. METHODS: A thorough search of electronic databases MEDLINE, Embase, Pubmed and Cochrane Library, from 1997 up to January 2011 was performed. An analysis was carried out, pooling the effects of outcomes of 4241 patients enrolled in 80 retrospective studies. For comparisons across studies, each reporting on only one endoscopic method, we used a random effects meta-regression of the log-odds of the outcome of treatment in each study. “Neural networks” as a data mining technique was employed in order to establish a prediction model of lymph node status in superficial …

Impact of margin status on long-term results of liver resection for hepatocellular carcinoma: single-center time-to-recurrence analysis

2020

Occult metastasis from the initial tumor and a de novo second primary hepatocellular carcinoma (HCC) were recognized as the main causes for the onset of early and late HCC recurrence, after liver resection (LR). This study aims to compare the time to recurrence after LR for HCC in which a margin ≤ 1 mm or > 1 mm was achieved. A single-center retrospective study involving 256 patients was conducted from June 2005 to June 2019. HCC patients resected with a radical surgical approach were investigated and stratified into groups A (resection margins ≤ 1 mm) and B (> 1 mm), as measured on final pathologic assessment. Kaplan–Meier estimators were used to estimate the probability of recurrenc…
