A case report of a patient with gallbladder agenesis resulting in a common bile duct injury.

ABSTRACT

INTRODUCTION: Congenital agenesis of the gallbladder is a rare embryological defect of the biliary system. While occurring equally in men and women, gallbladder agenesis is found clinically twice as often in women. Patients present with symptoms suggesting biliary colic. Abdominal ultrasound and cholecintigraphy or HIDA scan are usually inconclusive and, in some cases, may be read as positive for biliary colic. Patients can undergo surgery based on characteristics of pain. PRESENTATION OF CASE We report the case of a 60-year-old female presenting with symptoms of recurrent biliary colic and subsequently undergoing laparoscopic cholecystectomy after inconclusive workup. DISCUSSION: We offer a review of past reported cases as well as a new approach to such patients during the intraoperative period. An intraoperative decision should be made whether to continue and search for a possible ectopic gallbladder or investigate further with imaging studies. CONCLUSION: Gallbladder agenesis is a rare clinical presentation that the surgeon must be aware of. With inconclusive studies, the surgeon should consider congenital absence of the gallbladder and pursue further imaging if the gallbladder cannot be localized during the intraoperative period.
