A 52-year-old woman undergoes elective laparoscopic cholecystectomy for symptomatic gallstones. During the procedure, the surgeon carefully identifies the hepatocystic triangle (Calot's triangle) to avoid injury to the common bile duct.

The surgeon suspects a small bile leak from an accessory bile duct.
