BACKGROUND LAGB is a technique increasingly used in the USA. The aim of this study is to analyze the 5-year outcome in terms of weight loss and complications. METHOD We reviewed our prospective electronic database for all patients undergoing LAGB between 2002 and 2007. We assessed weight progression, complications, and reoperations. RESULTS We performed(More)
OBJECTIVE To evaluate safety, weight loss, and cardiometabolic changes in obese subjects implanted with the duodenal-jejunal bypass liner (DJBL) for 1 year. BACKGROUND The DJBL is an endoscopic implant that mimics the duodenal-jejunal bypass component of the Roux-en-Y gastric bypass. Previous reports have shown significant weight loss and improvement in(More)
Roux-en-Y gastric bypass (RYGBP) is one of the most commonly performed surgical procedures for morbid obesity. Several complications that may develop in the short- and long-term have been reported. We present a patient who presented with cancer in the bypassed stomach 8 years after RYGBP. Although the development of this lesion is rare and only a few cases(More)
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are conditions gaining increasing recognition in hepatology as a potential cause of cirrhosis and end-stage liver disease. Obesity is one of the main risk factors. The aims of this study were to determine the frequency of NAFLD in obese patients and to identify(More)
The accuracy of endoscopy and directed biopsy in the differential diagnosis of gastric lesions was evaluated by comparing the diagnoses of one endoscopic procedure (endoscopy and multiple directed biopsies) with the definitive diagnoses in 333 patients. The overall endoscopic and bioptic accuracy rate for all patients amounted to 98.8%. Separate accuracy(More)
We investigated in dogs the effect of graded frequencies of electrical vagal stimulation (1.5, 3, 6, and 12 cps) on pancreatic exocrine secretion and on portal blood levels of gastrin, secretin, cholecystokinin (CCK), vasoactive intestinal peptide (VIP), and somatostatin (STS). Stimuli of all four frequencies, each with a duration of 5 minutes, were applied(More)
From Jan 1978 to Dec 1984, 128 patients had a curative resection of colorectal carcinoma. A program for early detection and surgical correction of recurrences was initiated in 88 patients with a mean age of 61 years (range 24 to 85). Seventy two patients complied with the program involving clinical examination, chest X-ray, alkaline phosphatase and CEA(More)
Complications of bariatric operations include the development of nutritional deficiencies. If protracted vomiting is added, severe vitamin depletion could arise such as thiamine deficiency, resulting in the development of Wernicke's encephalopathy (WE). This article describes the rapid onset of WE in a 6-week postoperative morbidly obese woman. Because the(More)
The classic approach to renal stone disease includes shockwave lithotripsy, ureteroscopy or percutaneous nephrolithotripsy, and, in some cases, a combination of both. The usefulness of laparoscopy in this regard remains debated. In this report and video, we present our technique of laparoscopic pyelolithotomy assisted by flexible instrumentation to achieve(More)
