AIM Parastomal herniation of end colostomies can be chronically debilitating for patients and a difficult problem to treat. To prevent parastomal hernia (PSH) formation an extraperitoneal colostomy (EPC) approach has been developed in open colorectal surgery and some studies have suggested a potential advantage to this approach. Here we describe our(More)
BACKGROUND Single port cholecystectomy is increasingly performed. This procedure can be challenging, and we lack factors predicting the operative difficulty. AIMS To assess the role of surgeon experience and identify possible predictive factors of intraoperative difficulties. PATIENTS AND METHODS Sixty-one selected patients were prospectively enrolled(More)
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is gaining acceptance as a stand-alone bariatric procedure with proven efficacy on weight loss and obesity-related comorbidities. A specific and potentially severe complication of LSG is the staple line leak (SLL). Our aim was to report the SLL rate and its management in a prospective cohort of 378 LSGs. (More)
PURPOSE To assess the impact of mesh size and fixation devices on short-term outcomes in a consecutive series of tension-free laparoscopic abdominal wall repairs. METHODS Data for 120 consecutive, unselected patients undergoing tension-free laparoscopic incisional (n=63) or umbilical (n=57) hernia repair were prospectively collected. A multivariate(More)
Enterocutaneous fistulas (ECFs) are a surgical problem that is difficult to manage and they have a mortality rate between 6 and 33 % [1]. Many fistulas show a natural tendency to heal; however, the main problem in fistula care usually is adequate drainage of secretions from the wound. Vacuum-assisted wound care (V.A.C. , Kinetic Concept, Inc., San Antonio,(More)
BACKGROUND Free fatty acid (FFA) levels are raised in obesity as a consequence of increased production and reduced clearance. They may link obesity with insulin resistance. Bariatric surgery can result in considerable weight loss and reduced insulin resistance, but the mechanism of action is not well understood. Although drugs such as metformin that lower(More)
OBJECTIVE To assess the effect of Roux-en-Y gastric bypass (RYGB) on high-density lipoprotein cholesterol (HDL-C) concentration and its apolipoprotein A4 (ApoA4) content at 1 year after bariatric surgery in comparison with a hypocaloric diet. Secondary aim was to measure total cholesterol and triglycerides levels and insulin sensitivity after interventions.(More)
OBJECTIVE Enterocutaneous fistulas (ECFs) are an uncommon surgical problem, but they are characterized by a difficult management. Vacuum-assisted closure (VAC) therapy is a method utilized for chronic and traumatic wound healing. At first, VAC therapy had been contraindicated in the treatment of intestinal fistulas, but as time went by, VAC therapy revealed(More)
BACKGROUND The role of Barrett esophagus in carcinogenesis is widely accepted, but the significance of esophageal columnar mucosa without histological intestinal metaplasia, known as columnar-lined esophagus, is debated. MATERIAL/METHODS We studied 128 patients free of Helicobacter pylori with reflux-related symptoms and columnar mucosa in the esophagus(More)
