Superior Mesenteric Artery Syndrome After Roux-en-Y Gastric Bypass

Abstract

Superior mesenteric artery syndrome can be caused by the dramatic weight loss induced by a gastric bypass. This post weight loss surgery phenomenon may be far more prevalent and underdiagnosed than reported, and should be considered in all patients with greater than average weight loss at one year and who have persistent postprandial nausea and epigastric pain. This can be successfully treated by bypassing the obstruction, while maintaining the weight loss induced by the Roux-en-y gastric bypass.
