DU bleed: It is possible, given his history, that his du is bleeding again. If he never had any treatment for it, the ulcer may be back. He will need a double balloon endoscopy by a really skilled GI doc to get the scope down the roux limb and back up the biliopancreatic limb and into the duodenum and gastric remnant. He also needs proton pump inhibitors.
