Nonalcoholic steatohepatitis (NASH) is a morbid condition highly related to obesity. It is unclear if the macroscopic liver appearance correlates with the histopathologic findings. The goal of this prospective study was to determine the relationship between the intraoperative liver appearance and the histopathologic diagnosis of NASH in morbidly ob...

Double-balloon enteroscopy (DBE) is a useful method for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy. Depending on the distorted anatomy, endoscopic therapies with conventional scopes were very difficult or impossible before the advent of DBE and patients had to be submitted to a percutaneous or surgical ...

Leakage and fistulization of the gastro-jejunostomy have been the major drawback of Roux-en-Y gastric bypass (RYGBP) surgery. Most authors agree that operative treatment is the mainstay of therapy in patients with signs of sepsis. However, intestinal contents causing localized infection may impede healing of sutured leaks in some patients, and fist...

Background: In laparoscopic Roux-en-Y gastric bypass (LRYGBP) surgery, the anastomosis between the gastric pouch and the jejunum can be performed using a circular stapler, as described in the original publication by Wittgrove in 1994. The introduction of the circular stapler through the thick abdominal wall in morbidly obese patients can be challen...

Background: It has been proposed, that the dramatic amelioration of type 2 diabetes following Roux-en-Y gastric bypass (RYGBP) could by accounted for, at least in part, by changes in glucagon-like peptide-1 (GLP-1) secretion. However, human data supporting this hypothesis is scarce. Methods: A 12-month prospective study on the changes in glucose ho...

The increase in frequency of bariatric surgery has been accompanied by an increase in litigation involving patients and practitioners in this emerging field. With much being written about the medical aspects of bariatric surgery, the legal and risk management perspective of these procedures is now getting increased attention. This article examines ...

Late complications of open gastric bypass can include malnutrition, weight gain, stomal stenosis, and recurrent bleeding ulcers. Herein, we describe the case of a woman who had recurrent bleeding ulcers, after an open revision of a stenotic gastric bypass. She now underwent an uneventful laparoscopic revision of her gastrojejunostomy and was discha...

Background: Body image is a multifaceted construct commonly associated with obesity. This study examined changes in body dissatisfaction, and shape and weight concerns in bariatric surgery patients from baseline to 6 and 12 months post-surgery. Methods: 109 extremely obese patients who underwent gastric bypass surgery completed the Body Shape Quest...
