Double cystic duct preoperatively diagnosed and successfully treated with laparoscopic cholecystectomy: A case report

Abstract

IntroductionA single gallbladder with a double cystic duct is a very rare finding. In addition, few cases with this rare condition are preoperatively diagnosed. However, the preoperative confirmation or suspicion of this rare condition could facilitate safe laparoscopic cholecystectomy, which is a minimally invasive therapeutic modality for gallbladder disease. We herein present a case of gallstone disease in a patient with a double cystic duct who was preoperatively diagnosed and successfully treated with laparoscopic cholecystectomy. Presentation of caseA 57-year-old woman was admitted to our hospital with epigastric pain. Gallstone disease in the gallbladder and common bile duct was diagnosed by ultrasonography and computed tomography. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiography (ERC) revealed that the aberrant cystic duct arose from the cystic duct and communicated with the intrahepatic bile duct of the posterior segmental branch. Laparoscopic cholecystectomy was successfully performed in combination with intraoperative cholangiography. DiscussionIf an anomaly of the biliary duct system is not identified during surgery, it may turn out to be a bile leak. The preoperative diagnosis of a double cystic duct allows laparoscopic cholecystectomy to be performed safely in combination with intraoperative cholangiography. ConclusionsA single gallbladder with double cystic duct is a very rare anomaly. However, laparoscopic surgery can be facilitated by the use of preoperative and intraoperative images.
