A Double Cystic Duct With a Single Gallbladder Successfully Treated With Laparoscopic Cholecystectomy: A Challenge to...

Although the cystic duct has diverse variations, a double cystic duct is rarely found. Only 20 cases had been reported until late 2017. In the present study, we describe a 58-year-old woman with a double cystic duct who initially presented with a passed stone and pancreatitis concomitant with a gallbladder containing microlithiasis. The double cystic duct was not detected in preoperative endoscopic ultrasonography; and the anomaly was an incidental finding during laparoscopic cholecystectomy. The patient had no postoperative complications and was discharged uneventfully. Postoperative magnetic resonance cholangiography showed a normal biliary tree structure.
