Accessory bile duct: a rare but important anatomical variant.

An 84-year-old man presented with pancreatic adenocarcinoma. Following neoadjuvant chemoradiation, the patient underwent a pancreaticoduodenectomy, complicated by early bile leak. Re-exploration and intraoperative cholangiogram identified an accessory common bile duct draining segment 5 of the right hepatic lobe, which was then ligated. The patient underwent a complicated postoperative course eventually developing sepsis secondary to biliary stasis. He elected for comfort measures and passed away secondary to complications of sepsis.
