Early cholecystectomy (< 72 h) is associated with lower rate of complications and bile duct injury: a study of 109,862 cholecystectomies in the state of New York

The timing of cholecystectomy for acute cholecystitis has been debated with most studies favoring early cholecystectomy (< 72 h of onset). However, most reported studies are from single institution studies with only a few population-based studies. The purpose of this study is to compare clinical outcomes of patients undergoing cholecystectomy within 72 h of emergency department (ED) presentation to patients undergoing cholecystectomy following 72 h in a large statewide database.

The New York SPARCS administrative database was used to identify all adult patients presenting to the ED with a diagnosis of acute cholecystitis from 2005 to 2016. Patients aged < 18, missing data, or other biliary diagnoses were excluded from the analysis. Early cholecystectomy was defined as within 72 h of presentation to the emergency department. Early vs late groups were compared in terms of overall complications, bile duct injury (BDI), hospital length of stay (LOS), 30-days ED visits and readmissions. The linear trends of yearly early/late cholecystectomies were examined using a log-linear Poisson regression models. Multivariable logistic regression model was used to compare complications, BDI, and 30-day readmission/ED visits after controlling for confounding factors. Multivariable generalized linear regression for a negative binomial distributed count data was used to compare LOS.

Early cholecystectomy (< 72 h) is associated with fewer complications, specifically BDI, shorter LOS, and fewer 30-day readmissions and ED visits. For patients presenting to the ED for acute cholecystitis, early cholecystectomy should be preferred.
