Advanced gallbladder inflammation is a risk factor for gallbladder perforation in patients with acute cholecystitis

Background Acute perforated cholecystitis (APC) is probably the most severe benign gallbladder pathology with high rates of morbidity and mortality. The cause of APC has not been fully understood. We postulated that APC is a complication of advanced gallbladder inflammation. The aim of this study was to investigate the extent of gallbladder inflammation in patients with APC.
