Definitive diagnosis of a duplicate gallbladder can only be made intraoperatively: report of a case

Clin J Gastroenterol. 2014 Aug;7(4):338-41. doi: 10.1007/s12328-014-0494-2. Epub 2014 May 17.


Duplicated gallbladders are rare congenital anomalies that are important in clinical practice as they may cause clinical, surgical, and diagnostic problems. Here, we describe the case of a 79-year-old female patient who presented with acute cholangitis. Abdominal ultrasonography, endoscopic ultrasonography, computed tomography, and magnetic resonance imaging revealed an intrahepatic cystic lesion, suggesting communication with the intrahepatic bile duct; no evidence of a polypoid lesion within the cystic lesion was observed. Based on these findings, intrahepatic cholangiectasis, intrahepatic bile duct cystadenoma, and the presence of a duplicated gallbladder were suspected, and surgery was performed. During surgery, a tube inserted into the common bile duct from a cystic duct facilitated intraoperative cholangiography, which indicated the presence of a duplicated gallbladder. Thus, we believe that a duplicated gallbladder should be an additional consideration when typical gallbladder disease symptoms are present under certain circumstances. A multimodal imaging approach can help to establish the diagnosis preoperatively or intraoperatively.
