Right Hepatic Duct Drainage into Gallbladder Infundibulum: An Inevitable Bile Duct Injury during Laparoscopic Cholecystectomy

Laparoscopic cholecystectomy is gold standard for symptomatic gallstone and is world widely used for decades. With this minimally invasive approach, patients recovered from operation quicker than traditional open method. But biliary complication during this operation was not rare and had been reported. Literatures had suggested many preoperative image studies and intraoperative methods to avoid biliary complications. However, patients with biliary tree variation may have higher risk of bile duct injury during operation. Here, we present the patient with extremely rare biliary variation who encountered bile duct injury during laparoscopic cholecystectomy. The preoperative images, intraoperative findings, managements for complications, outcome and short review of the literature were recorded.
