He had undergone subtotal stomach-preserving pancreaticoduodenectomy for cancer of the ampulla of Vater six years earlier. Follow-up computed tomography (CT) three years earlier showed occlusion of the extrahepatic portal vein and the growth of collateral flow into the lateral segment of the liver, but there were no signs of recurrence of the cancer of the ampulla of Vater. The patient underwent prophylactic endoscopic variceal ligation for esophageal varices one year earlier. On admission, blood tests showed anemia and elevated liver enzyme and bilirubin levels. Esophagogastroduodenoscopy and colonoscopy failed to identify the site of bleeding. Double-balloon endoscopy showed the dilated blood vessels around the stenotic anastomosis of the choledochojejunostomy. A CT scan was consistent with total occlusion of the portal vein and varices around the choledochojejunostomy site. With a diagnosis of jejunal varices, laparotomy-assisted transcatheter variceal embolization was performed. Double-balloon endoscopy performed one month after laparotomy-assisted transcatheter variceal embolization showed no varices, and dilation of the stenotic anastomosis of the choledochojejunostomy was performed safely.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Jejunal varices should be included in the differential diagnosis of melena in patients with a previous history of surgery with a bilioenteric anastomosis and portal vein hypertension.
