HYPOTHESIS Enteric leakage is a significant complication of the Roux-en-Y gastric bypass (RYGB) procedure that can be treated successfully. DESIGN Retrospective study of 400 consecutive RYGB patients from 1999-2002. SETTING Community hospital with a university surgical residency. PATIENTS Hospital records of 400 morbidly obese patients who underwent gastric bypass surgery were reviewed. ...

HYPOTHESIS We hypothesized that we could develop a safe and effective technique for performing a totally robotic laparoscopic Roux-en-Y gastric bypass procedure using the da Vinci surgical system. We anticipated that the learning curve for this totally robotic procedure could be shorter than the learning curve for standard laparoscopic bariatric surgery. DESIGN Retrospective case comparison s...

Roux-en-Y gastric bypass surgery remains the major surgical option for individuals with medically complicated obesity. The importance of preoperative evaluation to permit identification of micronutrient deficiencies is being re-evaluated. The risk of complications related to pregnancy after gastric bypass supports careful follow-up. Micronutrient deficiencies are common in postoperative gastric...

The study aimed to examine the effect of gastric bypass on diabetic nephropathy (DN) in Chinese patients. A retrospective study of 101 samples with DN stages I to IV underwent Roux-en-Y gastric bypass. Anthropometric and biochemical parameters were assessed during a 1-year follow-up. Binary logistic regression analysis was used for predictors and ROC for cutoff points. There was significant red...

Percutaneous image-guided biopsies of pancreatic malignancies may prove challenging and nondiagnostic due to a variety of anatomic considerations. For patients with complex post-surgical anatomy, such as a Roux-en-Y gastric bypass, diagnosis via endoscopic ultrasound with fine-needle aspiration may not be possible because of an inability to reach the proximal duodenum. This report describes the...

OBJECTIVES Roux-en-Y gastric bypass is the gold standard for treating morbid obesity in this country. The totally laparoscopic performance of this procedure, although quite demanding and technically difficult, has revolutionized it; and the demand for it has skyrocketed. We describe 2 cases where it became necessary to convert the Y into a "W" while performing the procedure. METHODS A laparos...

A 41-year-old man presented with a 24hour history of melena and exacerbated epigastric pain 6 years after undergoing a laparoscopic Roux-en-Y gastric bypass for morbid obesity. He had been experiencing recurrent abdominal pain and episodes of melena in the preceding months. His past medical history also included protein C deficiency and a pulmonary embolism treatedwith anticoagulant therapy, wh...

OBJECTIVE Unlike gastric banding or sleeve gastrectomy procedures, intestinal bypass procedures, Roux-en-Y gastric bypass in particular, lead to rapid improvements in glycaemia early after surgery. The bypass of the proximal small bowel may have weight loss and even caloric restriction-independent glucose-lowering properties on hepatic insulin sensitivity. In this first human mechanistic study,...

BACKGROUND Performing endoscopic retrograde cholangiopancreatography in bariatric patients who underwent Roux-en-Y gastric bypass surgery is challenging due to the long anatomical route required to reach the biliopancreatic limb. AIM Assessment of the feasibility and performance of laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography. METHODS A retrospective mult...

Gastric cancer in the excluded stomach after Roux-en-Y gastric bypass is a rare finding and most reported diagnoses are made via surgery. Endoscopic access to the excluded stomach is difficult, even with balloon-assisted enteroscopy. We present the case of a 74-year-old woman with malignant gastric outlet obstruction of the excluded stomach, 41 years after Roux-en-Y gastric bypass. Minimally in...
