An H-Shaped Duplicated Gallbladder Presentingwith Acute Cholecystitis: A Case Report

Abstract

Background: Gallbladder (GB) duplication is a rare congenital biliary anomaly, which can increase iatrogenic biliary injuriesduring surgery. We report a case of duplicated GB presenting with acute cholecystitis in order to draw attention to its diag nosis and treatment. Case Report: A 57-year-old male patient with complaints of dyspepsia was diagnosed by ultrasound with duplicated GBcontaining gallstones, but the patient did not consent to undergo treatment. Three months later, the patient developed acutecholecystitis and obstructive jaundice, and was referred to our hospital. MR cholangiography showed an H-shaped duplicatedgallbladder with gallstones in the common bile duct, and then ERCP was performed. The laparoscopic view could not com pletely identify the anatomy of the GBs and cystic ducts; therefore, a conventional cholecystectomy was performed. Conclusion: Laparoscopic cholecystectomy for H-shaped duplicated GB cases with cholecystitis may be challenging dueto the duplicated cystic canals and GB inflammation. Anatomic variations should be identified preoperatively with properimaging modalities. Laparoscopic cholecystectomy should be primarily performed, as well as conventional cholecystectomyif required, to prevent biliary tract injuries.
