Unusual Bleeding From Hepaticojejunostomy Controlled by Adult Variable Stiffness Colonoscopy: Report of a Case and Literature Review

Abstract

Abstract We herein present a case of a 59-year-old man who had undergone pylorus preserving pancreaticoduodenectomy with regional lymph node dissection prior to episodes of melena. Series of conventional endoscopic investigations failed to identify the bleeding source. Enhanced computed tomography scan revealed complete obstruction of the main portal vein with numerous collateral veins running towards the hepatic hilus. Comprehensively, hemorrhage from the jejunal varices caused by postoperative portal hypertension was highly suspected. As the jejunal loop was out of reach, adult variable-stiffness colonoscope (AVSC) was utilized to solve the Roux-en-Y anatomy. Numerous telangiectasis and small varices at hepaticojejunostomy were observed and in the mean time, bleeding was noticed and endoclips were placed without any delay. Ectopic variceal bleeding in jejunal loop after pancreaticoduodenectomy is difficult to manage. We believe that AVSC is an alternative device when specialized jejunal endoscopy is not available.
