BACKGROUND AND OBJECTIVES As the number of bariatric operations performed increases, the number of patients requiring reoperation for failed weight loss is expected to proportionately increase. Natural orifice surgery is an alternative approach to revisional gastric bypass surgery when postoperative complications, such as dilatation of the gastrojejunostomy, gastrogastric fistula, and gastric p...

BACKGROUND The endoscopically placed enteral stent has emerged as a reasonable alternative to palliative surgery for malignant intestinal obstruction. This is a report of our experience with the use of enteral stents for nonesophageal malignant upper GI obstruction. METHODS Data on all patients who had undergone enteral stent placement were reviewed. Those with a diagnosis of pancreatic cance...

BACKGROUND/AIM The Glasgow prognostic score (GPS) is a predictor of outcome for several cancer types. The present study examined the significance of modified GPS (mGPS) in the prognosis of patients undergoing palliative surgery for stage IV gastric cancer. PATIENTS AND METHODS A total of 42 patients with stage IV gastric cancer treated with palliative gastrectomy and gastrojejunostomy were in...

OBJECTIVES We present a randomized controlled trial of laparoscopic gastric bypass comparing 2 techniques of gastrojejunostomy in patients with morbid obesity. METHODS Eighty consecutive patients underwent laparoscopic Roux-en-Y gastric bypass between September 2005 and August 2006. Patients were randomly assigned to 2 groups by the use of sealed envelopes. In group A, the gastrojejunal anast...

BACKGROUND Roux-en-Y gastric bypass (RYGB) is the most common bariatric operation; however, the mechanism underlying the profound weight-independent effects on glucose homeostasis remains unclear. Large animal models of naturally occurring insulin resistance (IR), which have been lacking, would provide opportunities to elucidate such mechanisms. Ossabaw miniature swine naturally exhibit many fe...

A 55-year-old woman with a past medical history of hypertension, diabetes mellitus, hyperlipidemia, and atrial fibrillation (on rivaroxaban) presented with a abdominal pain. Her past surgical history was significant for prior gastric bypass. Computed tomography scan showed a ventral hernia with several non-inflamed small bowel loops, pneumoperitoneum, and changes at the gastric bypass site incl...
