Roux-en-Y gastric bypass after failed vertical banded gastroplasty.

Background: Vertical banded gastroplasty (VBG) was the restrictive procedure of choice for many years. However, VBG has been associated with a high rate of long-term failure. We reviewed our experience of conversion of failed VBG to Roux-en-Y gastric bypass (RYGBP).

High mortality rate for patients requiring intensive care after surgical revision following bariatric surgery.

Background: To report the prognosis and management of patients reoperated for severe intraabdominal sepsis (IAS) after bariatric surgery (S0) and admitted to the surgical intensive care unit (ICU) for organ failure.

Methods: A French observational study in a 12-bed adult surgical intensive care unit in a 1,200-bed teaching hospital with expertise in bariatric surgery. From January 2001 to August 2006, 27 morbidly obese patients (18 transferred from other institutions) developed severe postoperative IAS (within 45 days).

[Sleeve gastrectomy: a new approach to bariatric surgery].

Over the last 15 years, obesity surgery has developed tremendously. The two most frequently practiced procedures are the adjustable gastric ring and gastric by-pass. A new intervention has recently appeared: the sleeve gastrectomy, an essentially restrictive intervention consisting of a vertical gastrectomy including the entire greater curvature of the stomach while leaving in place an approximately 100-ml gastric tube along the lesser curvature.

Skeletal myogenesis on highly orientated microfibrous polyesterurethane scaffolds.

Skeletal myogenesis is a complex process, which is known to be intimately depending on an optimal outside-in substrate-cell signaling. Current attempts to reproduce skeletal muscle tissue in vitro using traditional scaffolds mainly suffer from poor directionality of the myofibers, resulting in an ineffective vectorial power generation. In this study, we aimed at investigating skeletal myogenesis on novel biodegradable microfibrous scaffolds made of DegraPol, a block polyesterurethane previously demonstrated to be suitable for this application.

Mesoangioblast stem cells ameliorate muscle function in dystrophic dogs.

Duchenne muscular dystrophy remains an untreatable genetic disease that severely limits motility and life expectancy in affected children. The only animal model specifically reproducing the alterations in the dystrophin gene and the full spectrum of human pathology is the golden retriever dog model. Affected animals present a single mutation in intron 6, resulting in complete absence of the dystrophin protein, and early and severe muscle degeneration with nearly complete loss of motility and walking ability.

Laparoscopic sleeve gastrectomy (LSG): review of a new bariatric procedure and initial results.

Objective: To evaluate the outcomes and initial results of laparoscopic sleeve gastrectomy (LSG) and review of the literature.

Methods: A retrospective analysis of the initial ten patients who underwent LSG was performed. Study endpoints included operative time, complication rates, hospital length of stay, and percentage of excess body weight loss.

[Reflection on one case of acute peritonitis due to adjustable gastric banding during pregnancy].

Improving the information delivered to pregnant women with adjustable gastric banding is desirable. Indeed, we report a case of peritonitis on gastric banding due to Klebsiella pneumoniae complicated with fetal death. Then, we discuss the specific risks of infection on the gastric band during pregnancy.

Laparoscopic sleeve gastrectomy as an initial bariatric operation for high-risk patients: initial results in 10 patients.

Background: The outcomes and initial results of laparoscopic sleeve gastrectomy were evaluated.

Methods: A prospective study of the initial 10 patients who underwent laparoscopic sleeve gastrectomy (LSG) was performed. Study endpoints included operative time, complication rates, hospital length of stay and percentage of excess weight loss (%EWL).

Hepatic portal gas due to gastro-jejunal anastomotic leak after laparoscopic gastric bypass.

Gastrointestinal complications after laparoscopic Roux-en-Y gastric bypass (LRYGBP) are not uncommon. Leakage of the gastro-jejunal anastomosis is the main early surgical complication of LRYGBP. Hepatic portal venous gas (HPVG) has been described in association with a variety of pathologic conditions.

Laparoscopic gastric bypass versus laparoscopic adjustable gastric banding in the super-obese: a comparative study of 290 patients.

Background: Controversy exists regarding the best surgical treatment for super-obesity (BMI >50 kg/m2). The two most common bariatric procedures performed worldwide are laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGBP). We undertook a retrospective single-center study to compare the safety and efficacy of these two operations in super-obese patients.

Laparoscopic conversion of laparoscopic gastric banding to Roux-en-Y gastric bypass: a review of 70 patients.

Background: The feasibility and outcomes of conversion of laparoscopic adjustable gastric banding (LAGB) to laparoscopic Roux-en-Y gastric bypass (LRYGBP) was evaluated.

Methods: From November 2000 to March 2004, all patients who underwent laparoscopic conversion of LAGB to LRYGBP were retrospectively analyzed. The procedure included adhesiolysis, resection of the previous band, creation of an isolated gastric pouch, 100-cm Roux-limb, side-to-side jejuno-jejunostomy, and end-to-end gastro-jejunostomy.

Rhabdomyolysis after laparoscopic bariatric surgery.

Background: Postoperative rhabdomyolysis is an uncommon event. The aim of this study was to determine the incidence of rhabdomyolysis following laparoscopic obesity surgery.

Methods: Rhabdomyolysis was studied prospectively.

Obesity and diabetes as a risk factor for hepatocellular carcinoma.

Ten percent of patients who undergo resection for hepatocellular carcinoma (HCC) associated with chronic liver disease have no detectable cause for this underlying liver disease. Recent studies have shown that patients with cryptogenic chronic liver disease frequently have risk factors for nonalcoholic fatty liver disease (NAFLD). This study examines the incidence of risk factors for NAFLD in patients with chronic liver disease who underwent resection for HCC.

[Laparoscopic sigmoid resection for diverticulitis: is learning phase associated with increased morbidity?].

Aim: To assess retrospectively the results of laparoscopic sigmidectomy for diverticulitis, with intent to treat, in 58 consecutive patients operating by one surgeon compared with a control group operating by laparotomy.

Materials And Methods: From 1995 to 2001, 90 consecutive patients undergoing elective sigmoid resection for diverticulitis were divided into 3 groups: laparotomy (Group 1 : n = 32), first cases of laparoscopy (Group 2 : n = 29) and last cases of laparoscopy (Group 3 : n = 29). These 3 groups were similar according to age, sex, Body Mass Index (BMI), American society of anesthesia score (ASA), previous abdominal surgery, number of attacks of diverticulitis, and time between last attack and surgery.

A new etiology of acute abdominal emergencies in cirrhotic patient: secondary pneumococcal peritonitis with jejunitis.

We report the first case of secondary pneumococcal peritonitis associated with acute jejunitis in a 52-year-old homeless Child-Pugh C cirrhotic man without ascitis. The patient was admitted with clinical signs of peritonitis, and jaundice. Morphologic examination was unremarkable.
