“…In our cases, biliary drainage was achieved by pylorus-preserving Whipple surgery and hepaticojejunostomy, an approach that has only been described once in the literature. 10 - 12 Both of our patients had an uneventful post-operative course.…”

“…Therefore this case appears to be a new variant not previously reported or classified. Literature review showed similar reported cases of inadvertent BDI associated with DBCD during surgery [6, 7] and other configurations that could not be classified with existing classification systems [3, 5, 8] [Fig. 4].…”

“…Recognition of the existence of this anomaly is important to prevent iatrogenic biliary injury and most importantly help in making the right surgical decision. After the first case of DCBD reported by Vesalius in 1543, numerous cases of different variants have been reported in the English literature across the globe [2–5]. Only seven out of nine variants currently described in the literature can be classified by available classification systems [4].…”

Duplicated common bile duct, often associated with conditions like lithiasis, biliary cysts and pancreatobiliary maljunction, could result in highly morbid and potentially fatal biliary injuries. Precise preoperative diagnosis and classification still remain a challenge. A female patient undergoing emergency laparoscopic cholecystectomy for acute calculous cholecystitis sustained iatrogenic bile duct injury. A drainage tube was placed into the injured duct for post-operative conservative management. Post-operative tube cholangiogram revealed a double common bile duct with cystic duct opening distally. This was identified as a new variant not previously reported or classified. However rare, duplicated common bile duct could result in serious iatrogenic bile duct injury if unidentified during surgery. Knowledge of its existence is essential to avoid such injuries as preoperative diagnosis still remains a challenge. A thorough clinical and morphological study of previously reported variants is needed for a comprehensive classification to encompass newly discovered variants.

“…A and B coronal and axial magnetic resonance T2-weighted image showed the low signal septum in the dilated common bile duct which divided the extrahepatic bile duct into two parts, which connected to the left and the right hepatic duct respectively. C and D coronal maximum intensity projection magnetic resonance image and volume rendering image showed the dilated and duplicated common bile duct however, none of these were classified into classification system [8][9][10][11] (Fig. 4).…”

Background Duplication of the common bile duct (CBD) is extremely rare among the anatomical variations in the biliary tract system, which presents a septum within the CBD or an accessory CBD. In our study, we report a rare case of duplication of the common bile duct combined congenital biliary dilatation.we present a rare case of a septum in the dilated biliary tract. Case presentation We reported a 5-year-old Asian girl who had history of repeated abdominal pain for 4 days and aggravated for 1 day. Magnetic resonance cholangiopancreatography (MRCP) examination revealed duplicated common bile duct (DCBD) malformation with congenital biliary dilatation and distal cholelithiasis. The patient underwent choledochal cyst resection and biliary tract reconstruction and abdominal cavity irrigation and drainage under general anesthesia. A septum was found within the common bile duct during the operation. The septum divided the extrahepatic bile duct into two parts connected to the left and right hepatic ducts respectively and the gallbladder is attached to the repeated right bile duct which was not previously reported in the literature. Conclusions We complement and adjust the classification of common bile duct duplication by reviewing the literature.
