This study evaluates the role of early renal vasoconstriction in the pathogenesis of mercuric chloride (HgCl2)-induced acute renal failure (ARF) in the dog. Within 3 hr after mercury, glomerular filtration rate (GFR), from 45 +/- 4 25 +/- 2 ml/min, and renal blood flow (RBF), from 268 +/- 22 to 161 +/- 19 ml/min, decreased simultaneously. A rise in diuresis(More)
The least invasive of all surgical weight-lowering procedures is the adjustable laparoscopic gastric banding (ALGB) technique. A rare complication (0.9%–1.8% of patients) but one that may require surgical revision is leakage of the gastric banding device. This paper reports on the usefulness of technetium-99m scintigraphy for the assessment of gastric band(More)
UNLABELLED The purpose of this study was to assess the value of 99mTc-pertechnetate scanning in the diagnosis of gastric banding leaks. METHODS Three patients with morbid obesity received laparoscopic adjustable silicone gastric banding (ASGB), but no significant weight reduction was obtained. To exclude band leakage as the cause, four scintigraphic(More)
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has become a popular one-stage bariatric procedure with a proven efficacy on weight loss. However, the relationship between LSG and gastroesophageal reflux disease (GERD) remains a subject of debate. The objective is to determine the long-term effect of LSG on weight loss and reflux disease. METHODS A(More)
PURPOSE Dumping is currently seen as a negative side effect of Roux-en-Y gastric bypass (RYGB). However, it may help patients to comply with their prescribed diet. In this study, we assess the role of dumping on weight loss in patients who have undergone conversion of failed restrictive surgery into RYGB. METHODS An analysis was performed of 100(More)
