Obscure gastrointestinal (GI) bleeding is defined as bleeding from the GI tract that persists or recurs, with no obvious etiology, after esophagogastroduodenoscopy (EGD), colonoscopy, and radiologic evaluation of the small bowel. We present the case of a 17-yr-old girl who for two years had been suffering from recurrent episodes of melena and/or enterorrhagia. Fifteen yr earlier she had undergone a split-liver transplant with Roux-en-Y biliary reconstruction. A series of endoscopic and radiologic investigations had failed to find the source of the bleeding. Suspecting the presence of ectopic varices, we decided to perform single-balloon enteroscopy (SBE). We observed and aspirated a large amount of fresh red blood in the afferent loop until we found the hepaticojejunostomy. On the edge of the biliary-enteric anastomosis we observed a vascular lesion 5 mm in diameter. Judging this ectopic varix to be the source of bleeding, we placed two endoclips. The second clip placement caused varix rupture with a consequent massive hemorrhage, emergently and successfully treated with cyanoacrylate sclerotherapy. No episodes of rebleeding were observed, and no complications occurred during the entire hospital stay, and after six months of follow-up. This report highlights the importance of afferent loop examination in patients with obscure GI bleeding who have undergone liver transplant with Roux-en-Y biliary reconstruction. © 2010 John Wiley & Sons A/S.
