[Two Cases of Rupture of Elevated Jejunal Varices after Operation for Hilar Cholangiocarcinoma].

Case 1: A 64-year-old man with a chiefcomplaint ofbloody stools was seen in our hospital. He underwent an extended right lobe resection for hilar cholangiocarcinoma 3 years ago and was in the middle of chemotherapy for multiple metastases. Case 2: A 69-year-old man with a chiefcomplaint ofbloody emesis and stools was seen. He underwent left hepatic trisegmentectomy for hilar cholangiocarcinoma and ligation of the right portal vein for postoperative portal venous thrombus 6 months ago. After careful examination, the patients in both cases were diagnosed with bleeding of the jejunal varices formed at the site ofhepaticojejunostomy. The patient in Case 1 underwent percutaneous transhepatic obliteration ofvarices and the patient in Case 2 underwent transileocolic vein obliteration ofvarices. After hepatobiliary pancreatic surgery with biliary tract reconstruction, we should be aware of ectopic varices during differential diagnosis of gastrointestinal bleeding.
