Abstract:
Aims: Duplication of the gallbladder is a rare congenital anomaly. However, awareness of this anatomical variation is crucial when treating gallstone disease. We present the case of a patient with two gallbladders, incidentally found during laparoscopic cholecystectomy. We review the literature and discuss the associated surgical challenges.
Methods: Case presentation and literature review of the classification, clinical presentation, radiological diagnosis and management of gallbladder duplication.
Results: A 37 year old healthy man presented with a two year history of post prandial right upper quadrant abdominal pain. Routine blood investigations were normal and ultrasonography (US) demonstrated gallstones with normal biliary ducts. During laparoscopy he was found to have gallbladder duplication with a Y-shaped type cystic duct, this consisted of two ducts joining together to form a main cystic duct which drained into an otherwise normal common bile duct. No cholangiogram was performed. After meticulous dissection and demonstration of the anatomy, the cholecystectomy was performed. The patient recovered uneventfully and was discharged the next day. Histology showed gallstones and chronic inflammation in both
gallbladders.
Conclusions: A duplicate gallbladder is a rare congenital variation. Preoperative diagnosis can be challenging. Understanding its classification based on the relational anatomy to the biliary tree is essential to avoid biliary injuries. Imaging modalities such as US and computed tomography (CT) may not be sensitive enough. MRCP may demonstrate the biliary tree more clearly. Laparoscopic cholecystectomy can be safely performed, in the presence of symptomatic gallstone disease.
