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.
双胆总管在胆道系统的解剖变异中极为罕见。我们报告一例偶然发现的双胆总管病例,并从胚胎学角度讨论副胆总管的新解剖学发现。我们病例的一个独特之处在于副胆总管在胰内胆管水平处分支。从副胆总管的解剖学发现来看,在既往文献中没有与II型双胆总管类似的病例。我们推测这种无症状的解剖变异可能更常见,但未被诊断出来。
