Abstract
INTRODUCTION: Gallbladder duplication is a rare congenital anomaly of the biliary tree. Although a double gallbladder by itself is not clinically significant, complications of gallstone disease increases the complexity of the management. Preoperative recognition decreases the risk of complications during laparoscopic cholecystectomy. PRESENTATION OF CASE: Presented herein is the case of a 52 year old who presented with abdominal pain. A transabdominal ultrasound was suggestive of a gallbladder duplication with the larger gallbladder filled with cholelithiasis. Subsequent imaging studies, including an endoluminal ultrasound, confirmed the diagnosis and documented a choledocholithiasis. Endoscopic extraction of the biliary stone with subsequent laparoscopic cholecystectomy of both gallbladders was successfully performed. DISCUSSION: This case is being presented not only for the rarity of the condition but also of the challenges in management it poses. In gallbladder duplication, pathologic involvement of one gallbladder requires removal of both gallbladders. A high index of suspicion on initial scanning warrants further delineation of the important anatomic structures of the biliary tree to avoid perioperative complications. CONCLUSION: Laparoscopic cholecystectomy may be safely performed in patients with gallbladder duplication. Preoperative recognition with appropriate imaging modalities, including ultrasound and MRCP may avoid surgical complications. In cases where the anomaly is detected intraoperatively during cholecystectomy, meticulous dissection and intraoperative cholangiography will avoid iatrogenic injuries and lead to successful outcomes.
