National Trends in Interventions for Pediatric Gallstone Pancreatitis.

Introduction: Laparoscopic cholecystectomy (LC) during index hospitalization for gallstone pancreatitis is standard in adult populations. The objective of this study was to evaluate trends in use of LC and endoscopic retrograde cholangiopancreatography (ERCP) for children with gallstone pancreatitis. Materials and Methods: This retrospective cohort study used the Kids' Inpatient Database, spanning 2000-2019, to identify patients aged 18 years or younger with a principal diagnosis of gallstone pancreatitis. The Mann-Kendall trend test was used to assess trends over time. Results: Gallstone pancreatitis occurred in 5028 patients. The rate of LC during index hospitalization ranged from 55.4% to 63.8% (P = .76). Trends demonstrate that LC occurred on average hospital day 4.6 in 2000 and decreased to 3.4 in 2019 (P < .01). Among those undergoing LC, average length of stay (LOS) decreased from 6.8 days in 2000 to 5.1 days in 2019 (P < .01). The rate of ERCP alone decreased from 24.8% in 2000 to 14.0% in 2019 (P = .23). For those undergoing ERCP, average hospital day of ERCP decreased from 3.3 in 2000 to 2.3 in 2019 (P = .07). The rate of undergoing both an ERCP and LC decreased from 19.0% in 2000 to 8.5% in 2019 (P = .13). For patients who underwent either LC or ERCP, average LOS decreased from 7.0 days in 2000 to 5.1 days in 2019 (P < .01). For patients who did not undergo a procedure, average LOS decreased from 5.7 days in 2000 to 4.0 days in 2019 (P = .13). Conclusion: The proportion of LC performed during index hospitalizations for children with gallstone pancreatitis has been stable for two decades. However, trends indicate that interventions are occurring earlier, and LOS is becoming shorter.
