Double common bile duct with ectopic drainage into the stomach. Case report and review of the literature

Abstract

A rare abnormal biliary tract consisting in a double common bile duct with an ectopic biliary tree draining into the stomach is described. This congenital anomaly, associated with lithiasis in the ectopic duct, was detected for the first time on MR-cholangiopancreatography. Only 23 cases of abnormal biliary drainage into the stomach have been reported in the literature. Embryogenesis and potential risks, such as lithiasis in the ectopic duct and the development of gastric carcinoma, are discussed.

The clinical presentations of ectopic biliary drainage into duodenal bulbus and stomach with a thorough review of the current literature

“…Although, we do not know the exact frequency of ectopic biliary drainage, the frequency of the ectopic biliary drainage was found to be 2% in our series. In 2001, Bernard P et al reported only 23 cases with this condition by then [9]. In the literature, there were some other small case series and when we analyzed all these cases, we noticed that they were mostly patients with double choledochus [9-12].…”

Ectopic opening of the common bile duct into various sites of the upper digestive tract: a case series

“…Although ectopic opening of the biliary system into the stomach via the accessory bile duct was previously reported, until recently there have been only 4 case reports of the CBD directly opening into the stomach in the literature worldwide. [15][16][17][18][19][20] The most frequently reported ectopic opening of the CBD is the opening into the duodenal bulb. This was also Figure 1.…”

Aberrant Opening of the Common Bile Duct with Precancerous Change

“…In fact, diseases related with the biliary system are reported frequently in patients with ectopic CBD opening [2][3][4]9,[11][12][13][14][15][16][17][18]. In this study, CBD dilatation was found in 94% of the cases with or without intrahepatic biliary dilatation.…”
