A unique case of a double common bile duct with ectopic drainage into the gastric antrum: a case report and review of the literature on double duct variants

Abstract Variants of hepatic duct anomalies are widely discussed in the literature. Duplication producing a double and/or aberrant extrahepatic bile duct is one of the rarest congenital variants that have been sparingly reported. A 71-year-old female presented with right-sided abdominal pain. Computerized tomography demonstrated an enhancing soft tissue thickening in the gastric pylorus with extension into the left lobe of the liver and invasion of the left intrahepatic bile ducts and dilatation of the left intra- and extrahepatic biliary tract. Further examination led to a diagnosis of a double common bile duct with ectopic drainage into the gastric antrum. Recognition of this rare anomaly is of great importance because of the implications in respect of concomitant pathology, the potential short- and long-term sequelae and crucially for operative planning. Failing to appreciate the extent of anomalies may result in significant complications with the attendant morbidity.

Abstract Introduction Congenital choledochal malformations (CCMs) are characterized by intra- and/or extrahepatic bile duct dilatation. Five basic types (1–5) are recognized in Todani's classification and its modifications, of which types 1 and 4 typically have an associated anomalous pancreatobiliary junction and common channel (CC). We describe two cases with previously undescribed features. Case Report 1 Antenatal detection of a cyst at porta hepatis was made in an otherwise normal girl of Iranian parentage. She was confirmed to be a CCM (20 mm diameter), postnatally, with no evidence of obstruction. Surgical exploration was performed at 12 weeks. She had an isolated cystic dilatation of the right-hepatic duct only. The left-hepatic duct and common bile duct (CBD) were normal without a CC. Histology of the resected specimen showed stratified squamous epithelium. Case Report 2 A preterm (31 weeks of gestation) boy of Nigerian parentage was presented. His mother was HIV + ve and he was treated with nucleoside reverse transcriptase inhibitors following birth. He had persistent cholestatic jaundice and a dilated (10 mm) bile duct from birth. Although the jaundice resolved, the dilatation persisted and increased, coming to surgery aged 2.5 years. This showed cystic dilatation confined to the common hepatic duct, and otherwise normal distal common bile duct and no CC. Result Both underwent resection with the Roux-en-Y hepaticojejunostomy reconstruction to the transected right-hepatic duct alone in case 1, leaving the preserved left duct and CBD in continuity, and to the transected common hepatic duct in case 2. Conclusions Neither choledochal anomaly fitted into the usual choledochal classification and case 1 appears unique in the literature.

New Variant

ABSTRACT Extrahepatic bile duct duplication is a rare biliary anomaly often associated with conditions like cholecysto-choledocholithiasis, choledochal cyst and malignancy. Precise preoperative diagnosis using conventional radiologic imaging still remains a challenge and use of existing classification system is equally confusing. A female patient diagnosed with choledochal cyst by magnetic resonance cholangiopancreatography was found to have an associated new variant of double common bile duct during surgery. The variant discovered could not be classified by existing classification systems and was missed by preoperative imaging. Recognition of existence of this anomaly that warrants careful dissection during biliary surgery is necessary to avoid inadvertent biliary injury as preoperative diagnosis still remains a challenge. Review of existing classification systems is required to include newly discovered variants.

Abstract Background Extrahepatic bile duct duplication is an extremely rare congenital anomaly in which two common bile ducts exist. There are five different types of this anomaly and we present an unusual variant of duplication of an extrahepatic biliary system of type Va variety. Case presentation This case report describes a 63-year-old women from rural Nepal who presented with type Va of duplicated extrahepatic bile duct, with chronic calculous cholecystitis and choledocholithiasis. She was managed with cholecystectomy with hepatic ductoplasty and hepaticojejunostomy. Conclusion A rare case of double common bile duct (type Va) complicated by choledocholithiasis, cholangitis, and chronic cholecystitis is reported here. Rare cases are sometimes overlooked by modern diagnostic techniques. Correct diagnosis helps appropriate surgical intervention.

Papillary Neoplasm

Duodenum mucinous carcinoma is very rare, and the prognosis of the patient is very bad, especially when the tumor is invasive to other organs. In this case, duodenum carcinoma was invasive to common bile duct and transverse colon. Mucinous fluid, which was secreted from a duodenum tumor, was found in the dilatated bile duct. The intraductal papillary neoplasm of the bile duct was considered a differential diagnosis. We performed aggressive resection and had a good prognosis. A 74-year-old woman received a diagnosis of cholangitis and was treated with antibiotic drugs. Endoscopic retrograde cholangiopancreatography revealed a defect in the lower common bile duct with the mucoid fluid. We suspected intraductal papillary neoplasm of the bile duct, but no malignant cells were detected. One year later, gastrointestinal fiberscopy revealed a villous tumor in the postbulbar portion of the duodenum; adenocarcinoma was detected in biopsy specimens. Computed tomography revealed dilatation of the duodenum with an enhanced tumor, and dilatation of both the common and intrahepatic bile ducts. Magnetic resonance cholangiopancreatography revealed that the duodenum was connected with the common bile duct and ascending colon. We resected the segmental duodenum, extrahepatic bile duct, left lobe of liver, a partial of the transverse colon, and associated lymph nodes. Although the advanced duodenal carcinoma had poor prognosis, the patient was alive, without recurrence, 5 years after the operation.

Variant Anatomy

Proximal extrahepatic bile ducts are the biliary tree segment within formal boundaries from cystic ductcommon hepatic duct junction to sectoral hepatic ducts. Despite being a focus of attention of diagnostic and interventional radiologists, endoscopists, hepatobiliary surgeons and transplantologists they weren’t comprehensively described in available papers. The majority of the authors regard bile duct confluence as a group of merging primitively arranged tubes providing bile flow. The information on the proximal extrahepatic bile duct embryonal development, variant anatomy, innervation, arterial, venous and lymphatic supply is too general and not detailed. The present review brought together and systemized exiting to the date data on anatomy and function of this biliary tract portion. Unique, different from the majority of hollow organs organization of the proximal extrahepatic bile duct adapts them to the flow of the bile, i.e. viscous aggressive due to pH about 8.0 and detergents fluid, under higher wall pressure than in other parts of biliary tree.
