Bilobed Gallbladder Presenting as a Double Hartmann’s Pouch: A Rare Anatomical Variant During Laparoscopic Cholecystectomy

Year: 2026

Type: article

Abstract: Anatomical variations of the gallbladder may increase the risk of biliary injury during cholecystectomy if unrecognized. We report a rare intraoperative finding of a bilobed gallbladder presenting as a double Hartmann’s pouch in a patient undergoing laparoscopic cholecystectomy for symptomatic cholelithiasis. Preoperative ultrasonography did not reveal this anomaly. Intraoperatively, two prominent pouch-like outpouchings were noted at the gallbladder neck. Careful dissection of Calot’s triangle enabled clear delineation of anatomy, revealing a single cystic duct and artery. The critical view of safety was achieved prior to division of structures. The procedure was completed laparoscopically without complications. This case highlights the importance of recognizing atypical gallbladder morphology and adhering to safe surgical principles to prevent bile duct injury.
