BACKGROUND: The two approaches for performing cholecystectomy are open and laparoscopic ones. This study aims to characterize national trends of cholecystectomies in the United States (US) and determine differences by approach, age group, primary payer, teaching status and location of healthcare center.
METHODS: Retrospective analysis of patients undergoing cholecystectomy was done using the US National Inpatient Sample from 1997 to 2011. Trends in open and laparoscopic cholecystectomy were analyzed, as well as comparison between age groups, primary payer, location and teaching status of hospitals operations were performed at.
RESULTS: Around 6 million cholecystectomies performed from 1997 to 2011. The laparoscopic approach was significantly more common than the open (p-value <0.001). A significant decrease in open cholecystectomies is seen since 1997. Age group of 65-84 had significantly the most cases in the open approach (p-value <0.001), while in laparoscopic the 18-44 age group had the significantly highest amount (p-value <0.001). Medicare covered the most cases for open, while private insurance covered the most in the laparoscopic approach. Most cases were performed in urban, private non-profit, non-teaching hospitals in both groups. In the laparoscopic group the South had a significantly higher (p-value <0.001) number of cases compared to all other U.S. regions.
CONCLUSIONS: Cholecystectomies remained constant from 1997 to 2011. The number of open cholecystectomies decreased over time in favor of laparoscopic ones. More funding should be given to private non-teaching hospitals as they perform the majority of cholecystectomies nationwide. Better management of cholecystectomy risk factors is needed in the South.
