Duplication of the extrahepatic bile duct is an extremely rare anomaly. There are five types of this anomaly, with type V being the least common variant. Only two cases of type V (one each of type Va and type Vb) have been reported. Here we report the second case of type Va duplication of the common bile duct presenting with choledocholithiasis. The patient underwent open choledocholithotomy and T-tube choledochostomy after failed endoscopic stone clearance. Duplication of the bile duct was detected on T-tube cholangiogram, which was confirmed by magnetic resonance cholangiopancreaticography (MRCP). No associated pancreaticobiliary maljunction was found on the imaging.
肝外胆管重复是一种极其罕见的异常情况。这种异常有五种类型，其中V型是最不常见的变体。仅报告过两例V型（Va型和Vb型各一例）。在此，我们报告第二例表现为胆总管结石的Va型胆总管重复病例。在内镜下结石清除失败后，该患者接受了开腹胆总管切开取石术和T管胆总管造口术。T管胆管造影检测到胆管重复，磁共振胰胆管造影（MRCP）证实了这一情况。影像学检查未发现相关的胰胆管合流异常。
