A case of double common bile duct in a deceased donor for transplantation

Abstract

A double common bile duct is extremely rare among the anatomical variations in the biliary tract system. We report an incidentally encountered case of the double common bile duct and discuss the novel anatomical findings of the accessory common bile duct from the viewpoint of embryology. A unique point of our case is that the accessory common bile duct bifurcated at the level of the intrapancreatic bile duct. There is no similar case in the previous literature among type II double common bile duct in the viewpoint of anatomical findings of the accessory common bile duct. We assume that this asymptomatic anatomical variation may be present more commonly, but not diagnosed.

Morphometric Analysis of Common Bile Duct: A Cadaveric Study

“…Rodríguez-Luna MR, et al [23] conducted a radiological study named transcystic intraoperative cholangiogram showed common bile duct duplication without signs of the biliary obstruction. Also, a case of double CBD was reported by Imamura H.et al and discussed the novel anatomical fi ndings of the accessory CBD from the viewpoint of embryology [24]. However, the present study has not come across the duplication of the common bile duct.…”
