Prevalence of cholecystitis in gallbladder histology following clinical pancreatitis: cohort study

Cholelithiasis occurs in 10% of the population, most commonly caused by gallstone formation from bile salt cholesterol hypersaturation. Common presentations include cholecystitis and pancreatitis, yet these two gallstone diseases rarely seem to happen simultaneously. Gallstone pancreatitis occurs when gallstones escape from the gallbladder and become lodged within the common bile duct causing back pressure onto proximal organs. If gallstones are the aetiology of pancreatitis, cholecystectomy is performed. This prevents further gallstones migration rather than treating cholecystitis. In such patients, what does the gallbladder histology show and what is its relevance? The only previous study found 39.6% of gallbladders in gallstone pancreatitis demonstrated cholecystitis on histology.
