Abstract
An incidental finding of absent gall bladder in laparoscopic exploration - a rare occurrence in extra hepatic biliary anatomy
Highlights
Congenital agenesis of the cystic duct and gall bladder is one of the rare occurrences seen in extra hepatic biliary anatomy
Considering the above facts a clinical diagnosis of chronic cholecystitis was made and she was scheduled for laparoscopic cholecystectomy due to persistent symptoms
She had an uneventful post-operative period. She was scheduled for post-operative Endoscopic Retrograde Cholangiopancreatography (ERCP) which confirmed the diagnosis of absent gall bladder and cystic duct with normal intra hepatic ducts and extra hepatic bile ducts
Summary
Congenital agenesis of the cystic duct and gall bladder is one of the rare occurrences seen in extra hepatic biliary anatomy. It represents a variation in the process of embryogenesis of extra hepatic biliary tree with the incidence of 0.01% - 0.06% [1]. This itself can present as an isolated occurrence or associated with other congenital malformations of the extra hepatic biliary tree and the liver [2]. Half of the patients present with symptoms similar to biliary colic or chronic cholecystitis despite an absent gall bladder [10]
