BACKGROUND: The Gallstone Pancreatitis: Admission vs Normal Cholecystectomy (Gallstone PANC) Trial demonstrated that cholecystectomy within 24 hours of admission (early) compared with after clinical resolution (control) for mild gallstone pancreatitis, significantly reduced 30-day length-of-stay (LOS) without increasing major postoperative complications. We assessed whether early cholecystectomy decreased 90-day healthcare use and costs. STUDY DESIGN: A secondary economic evaluation of the Gallstone PANC Trial was performed from the healthcare system perspective. Costs for index admissions and all gallstone pancreatitis-related care 90 days post-discharge were obtained from the hospital accounting system and inflated to 2020 USD. Negative binomial regression models and generalized linear models with log-link and gamma distribution, adjusting for randomization strata, were used. Bayesian analysis with neutral prior was used to estimate the probability of cost reduction with early cholecystectomy. RESULTS: Of 98 randomized patients, 97 were included in the analyses. Baseline characteristics were similar in early (n = 49) and control (n = 48) groups. Early cholecystectomy resulted in a mean absolute difference in LOS of -0.96 days (95% CI, -1.91 to 0.00, p = 0.05). Ninety-day mean total costs were $14,974 (early) vs $16,190 (control) (cost ratio [CR], 0.92; 95% CI, 0.73-1.15, p = 0.47), with a mean absolute difference of $1,216 less (95% CI, -$4,782 to $2,349, p = 0.50) per pati...
