Introduction Subtotal cholecystectomy (STC) has become recognized as a “bailout procedure” to prevent bile duct injury in patients undergoing laparoscopic cholecystectomy (LC). Predictors of conversion to STC have not been identified because LC difficulty varies based on pericholecystic inflammation. We analyzed data from patients enrolled in a previously performed multi‐institutional retrospective study of the optimal timing of LC after gallbladder drainage for acute cholecystitis (AC). These patients presumably had a considerable degree of pericholecystic inflammation. Methods In total, 347 patients who underwent LC after gallbladder drainage for AC were analyzed to examine preoperative and perioperative factors predicting conversion to STC. Results Three hundred patients underwent total cholecystectomy (TC) and 47 underwent conversion to STC. Eastern Cooperative Oncology Group Performance Status (ECOG PS) (P
