Ectopic opening of the common bile duct into the stomach

“…Ectopic opening of the CBD into any site other than the second portion of the duodenum is quite rare. However, it can terminate at anomalous sites, including the third or fourth portion of the duodenum, the pyloric canal or duodenal bulb (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20).
