“…Normal anatomy of the biliary tree is found in 58% of the population, with anomalies occurring in the remaining 42% 4 . The most common abnormalities are observed at intrahepatic bile duct, such as, for example, right posterior bile duct aberrant drainage into Five months later, the patient developed biliary symptoms again, for which a new MRC was carried out, which disclosed a common bile duct in normal anatomical position, of up to 10 mm in diameter and with clear repletion defects within, as well as a cystic duct, and the posterior hepatic segments that drained through this pathway, and a second system that from two hepatic bile ducts drained the anterior liver segments, which merged into a 12-mm dilated common accessory bile duct that drained into the stomach at the posterosuperior area of the antrum, 1-2 cm from the pylorus, and that showed an image of 8-mm distal lithiasis.…”

“…Common bile duct duplication is an exceptional congenital alteration 2 . According to Choi et al classification 3 , Type IV has two common bile ducts, with one running into the duodenum and the other into different segments of the upper gastrointestinal tract, such as the stomach, duodenum, or main pancreatic duct (which is known as common accessory bile duct) 2,4 .…”

Introduction: Duplicity of the common bile duct is an unusual congenital disorder. Case report: A 80-year-old woman with duplication of the common bile duct with retrograde endoscopic cholangiopancreatography (ERCP) who did not resolve the symptoms. Discussion: Our case is a variant of Type IV to the classification of duplicity of the common bile duct. The magnetic resonance cholangiography and pre-surgical ERCP allows assessment of the bile ducts, their caliber, and assessment of abnormalities. The treatment before duplicity of the common bile duct will depend on the clinic and the type of opening of the accessory common bile duct. Conclusions: It is important to perform a pre-surgical study and during surgery with intrasurgical cholangiography.

“…DCBD is an extremely rare congenital anomaly of the biliary system. Since Vesarius first reported it in 1543, only 24 cases had been reported in the western literature until 1986[ 3 ]. However, cases of DCBD are reported more often in the eastern literature.…”

“…To the best of our knowledge, this patient is the eighth case of DCBD Type V to be reported. Among the previously reported cases, 5 cases were diagnosed with choledocholithiasis[ 3 , 8 - 11 ]. There were 2 cases[ 9 , 11 ] that had choledocholithiasis in both extrahepatic bile ducts; one underwent surgery as the stones were not completely removed using ERCP[ 11 ], and another case successfully underwent stone extraction in one session of ERCP[ 9 ].…”

BACKGROUND Duplication of the extrahepatic bile duct (DCBD) is an extremely rare congenital anomaly of the biliary system. There are five types of DCBD according to the latest classification. Among them, Type V is characterized by single drainage of the extrahepatic bile ducts. Reports on DCBD Type V are scarce. CASE SUMMARY A 77-year-old woman presented with recurrent epigastric pain but without fever or chills. Computed tomography revealed a dilated common bile duct (CBD) that harboured multiple choledocholithiasis. Endoscopic retrograde cholangio-pancreatography (ERCP) was performed, and the stones were extracted using a Dormia basket. She was discharged without any complications; however, she visited the emergency department a day after she was discharged due to epigastric pain and fever. Laboratory findings were suggestive of cholestasis. After urgent ERCP for stone removal, magnetic resonance cholangiopancrea-tography was performed to evaluate remnant choledocholithiasis. Magnetic resonance cholangiopancreatography revealed a DCBD Type Va and remnant choledocholithiasis in the right CBD. Both CBDs were accessed, and the stones were cleared successfully during a subsequent ERCP. CONCLUSION In this article, we report an extremely rare case of DCBD manifesting as recurrent pyogenic cholangitis. This case highlights the importance of recognizing DCBD because stones in the unrecognized bile duct could make the patient’s prognosis critical.

“…Duplicated bile ducts are quite common in reptiles, birds, and fish; but in humans, they are very rare. [ 4 ] The mechanism of this anomaly is believed to be related to the disruption of early embryogenesis development and preservation of an extrahepatic accessory duct. [ 3 ] The real incidence rate of this anomaly might never be known because many individuals with this anomaly are asymptomatic throughout their whole lives, making it impossible to even suspect the presence of the anomaly.…”

Rationale:Duplication of the extrahepatic bile duct is an extremely rare congenital anomaly of the biliary system.Patient concerns:A 44-year-old woman presented with a history of continuous upper abdominal pain and vomiting.Diagnoses:Magnetic resonance cholangiopancreatography (MRCP) disclosed diffuse dilatation of the intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP) showed the presence of two extrahepatic bile ducts with calculus at the distal end of the CBD.Interventions:Laparoscopic cholecystectomy (LC) was performed after an ERCP. Choledochoscopy, performed during the operation, showed duplicated common bile duct and the cystic duct was seen opening at the right side of the extrahepatic duct.Outcomes:The patient was doing well after 6 months of follow-up.Lessons:We reported a case of a double common duct with choledocholithiasis and gallstone. This rare anomaly may lead to cholangitis, common bile duct injury during surgery, malignancy occurrence, and should be treated with extreme care.
