Two's Company: A Case Report Presenting Diagnostic and Surgical Challenges of a Rare Congenital Duplicated...

Duplicated gallbladders are a rare congenital anomaly. Most cases are asymptomatic, but duplicated gallbladders can present significant diagnostic and surgical challenges, particularly due to the risk of bile duct injury or retained stones if not recognized preoperatively. Advanced imaging modalities such as ultrasonography, magnetic resonance cholangiopancreatography, and intraoperative cholangiography are often required for accurate diagnosis, though variability in anatomical presentation complicates preoperative identification. Clinical vigilance is therefore essential, especially in atypical biliary presentations. We present the case of a 56-year-old male patient with a duplicated gallbladder who successfully underwent robotic-assisted cholecystectomy. The case report adheres to the CARE (CAse REport) guidelines to ensure transparency and completeness, detailing the clinical history, diagnostic approach, surgical management, and outcomes.
