BACKGROUND: Subtotal cholecystectomy is increasingly recommended as a bailout strategy for the difficult gallbladder, yet its long-term durability and the risk profile of subsequent completion cholecystectomy remain incompletely defined.
STUDY DESIGN: We performed a population-based retrospective cohort study of adults undergoing laparoscopic or open subtotal cholecystectomy for acute cholecystitis from 2012 to 2021 using Healthcare Cost and Utilization Project state databases from New York and Florida. The primary endpoint was remnant cholecystitis, defined as a postoperative emergency, inpatient, or outpatient diagnosis of cholecystitis or need for subsequent cholecystectomy. Kaplan-Meier analysis estimated cumulative incidence. Secondary outcomes included completion cholecystectomy and bile duct injury requiring surgical repair.
RESULTS: Among 2,682 patients (98.7% laparoscopic), the cumulative incidence of remnant cholecystitis was 13.3% during a median follow-up of 2 years (interquartile range [IQR] 0.7 to 4.1). The median time to developing remnant cholecystitis was 28 days (IQR 13 to 91), with 79.7% occurring within 6 months. Only 70 patients (2.6%) underwent completion cholecystectomy at a median of 103 days (IQR 43 to 202). Completion cholecystectomy was performed via open surgery in 47.1% of patients and was associated with a 7.1% bile duct injury rate and median length of stay of 3 days (IQR 1 to 7), compared with a 0.9% bile duct injury rate for subtotal cholecystectomy overall.
CONCLUSIONS: Although remnant cholecystitis occurred in 13.3% of patients after subtotal cholecystectomy, few required completion cholecystectomy. When necessary, completion cholecystectomy was frequently open and associated with a substantially higher bile duct injury rate, supporting referral to experienced hepatobiliary centers for reoperation.
