A 58-year-old male underwent pancreatoduodenectomy based on a diagnosis of middle bile duct cancer. Because abdominal drainage revealed bile leakage 5 days postoperatively, leakage at the site of cholangiojejunostomy was diagnosed, and continuous aspiration was performed. Seventeen days postoperatively, pus was discharged through the abdominal drain. Because bleeding was detected by abdominal drainage, and shock ensued 20 days postoperatively, emergency abdominal angiography was carried out to identify the bleeding site. A false aneurysm in the proper hepatic artery and extravasation from the gastroduodenal artery stump were recognized, and therefore, the proper hepatic artery and common hepatic artery were embolized at a site distal to the false aneurysm using microcoils. Celiac arteriography after transcatheter arterial embolization (TAE) did not show extravasation, and revealed blood flow from the right inferior phrenic artery to the liver. Liver function was normal after TAE, and the patient recovered and was discharged from the hospital 54 days postoperatively. This paper presents a patient in whom intraabdominal bleeding due to leakage at the site of cholangiojejunostomy complicated by infection was successfully treated by hemostasis with TAE.
