Here we report the case of a left hepatic trisectionectomy for hilar cholangiocarcinoma with a rare aberrant biliary duct of segment 5 which to the best of our knowledge has never been reported in previous literature. Case presentation A 56-year-old Asian female initially presented with intrahepatic bile duct dilatation in the left lateral sector left paramedian sector and right paramedian sector. Simultaneous cholangiography from a percutaneous transhepatic biliary drainage tube in biliary duct of segment 8 and endoscopic nasobiliary drainage tube in biliary duct of segment 3 revealed drainage of the right lateral sectoral branch into the common hepatic duct and the aberrant drainage of segment 5 into the right lateral sectoral branch. The left hepatic duct right paramedian sectoral duct and the confluence of the right lateral sectoral duct were narrowed. Left hepatic trisectionectomy was successfully performed with careful dissection and division of the aberrant biliary duct of segment 5. Conclusion For safe liver resection it is important to perform a detailed anatomic evaluation of the intrahepatic ducts both preoperatively and intraoperatively. Introduction Advances in surgical procedures for liver resections and partial liver transplantation have led to the need for a better more detailed understanding of biliary anatomy and potential variations to perform a safe operation.
