BACKGROUND Worldwide, the incidence of morbid obesity is increasing, and surgery is the only effective longterm treatment. Laparoscopic sleeve gastrectomy (LSG) is associated with acceptable weight loss and reduced comorbidities. It is considered a safe procedure with sporadic complications. This publication aims to describe failures of LSG in terms of ineffective weight loss or early weight re...

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 bypass surgery is a common corrective procedure for obesity that is associated with many risks. Recent studies describing the use of autologous platelet gel (APG) have shown promise in preventing certain operative complications and improved healing processes. These improvements have been credited to the concentrated platelets and growth factors present in APG, as well as the native conc...

The global obesity epidemic has resulted in significant morbidity and mortality. However, the medical treatment of obesity is limited. Gastric bypass is an effective surgical treatment but carries significant perioperative risks. The gut hormones, peptide tyrosine tyrosine (PYY) and glucagon-like peptide 1 (GLP-1), are elevated following gastric bypass and have been shown to reduce food intake....

We describe six patients (five women and one man; median age, 47 years; range, 39 to 54) with postprandial symptoms of neuroglycopenia owing to endogenous hyperinsulinemic hypoglycemia after Roux-en-Y gastric bypass surgery. Except for equivocal evidence in one patient, there was no radiologic evidence of insulinoma. Selective arterial calcium-stimulation tests, positive in each patient, were u...

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...

Effect of Duodenal-Jejunal Bypass on Skeletal Muscle Insulin Signaling in GotoKakizaki Rats by Ruben Carnell Sloan, III July, 2009 Director: Timothy P. Gavin, Ph.D. DEPARTMENT OF EXERCISE AND SPORT SCIENCE Gastric bypass surgery (RYGBP) for the treatment of obesity has proven to clinically reverse type 2 diabetes mellitus. RYGBP involves both gastric reduction and bypass of the proximal small i...
