Double gallbladder-a laparoscopic management.

A rare case of gallbladder duplication, an unusual biliary anomaly is reported in a young female patient presenting with acute cholecystitis. After a confirmed diagnosis of double gallbladder was made by sonography, endoscopic retrograde cholangio-pancreaticography (ERCP), and magnetic retrograde cholangio-pancreaticography(MRCP), both gallbladders were removed laparoscopically. On histology both gallbladders showed cholesterolosis. Detailed preoperative investigations are required for an accurate preoperative diagnosis before considering laparoscopic cholecystectomy to avoid inadvertent damage to biliary ductal system and overlooking of second gallbladder during surgery.
