Bilobed gallbladder discovered during laparoscopic cholecystectomy: a tale of two lobes and one duct

Bilobed gallbladder (BG) is a rare congenital anomaly with just 24 cases documented in medical literature in the past 127 years. There are only three documented cases of BG's managed with laparoscopic cholecystectomy, and in all three cases the bilobed anomaly was discovered preoperatively. We present a case of symptomatic cholelithiasis in a BG that was discovered intraoperatively. Both the surgical techniques used to ensure complete and safe removal of all gallbladder components and the elements associated with the preoperative diagnosis of these rare anomalies are discussed.
