Gallbladder duplication: evaluation, treatment, and classification

J Pediatr Surg. 2010 Feb;45(2):443-6. doi: 10.1016/j.jpedsurg.2009.12.015.


Duplicate gallbladder is a rare congenital anomaly resulting from abnormalities in embryogenesis during the fifth and sixth weeks of gestation. Approximately 210 cases have been described. Variations include duplicate, triplicate, and septated gallbladder. We encountered a 15-year-old girl with both a duplicated gallbladder and a duplicated cystic duct who underwent successful laparoscopic cholecystectomy. This combination is extremely unusual, and based upon our findings in this case and a review of the literature, we propose the Unified Classification of Multiple Gallbladders.
