Cholecystectomy during or within 4 weeks of hospitalization for acute biliary pancreatitis is recommended by guidelines.
Dr Susan Hutfless and colleagues from Maryland, USA examined adherence to the guidelines for incident mild-to-moderate acute biliary pancreatitis, and the effectiveness of cholecystectomy to prevent recurrent episodes of pancreatitis.
Individuals in the 20102013 MarketScan Commercial Claims & Encounters database with a hospitalization associated with International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes of 577.0 for acute pancreatitis and 574.x for gallstone disease were eligible.
The team considered guideline adherence as cholecystectomy within 30 days of the first/index hospitalization for biliary pancreatitis.

Individuals with and without guideline-adherent cholecystectomy were compared for subsequent hospitalization for acute or chronic pancreatitis using a Cox proportional hazards model adjusted for age, sex, comorbidities, and length of index hospital stay.
The researchers found that of the 17,010 patients who met the inclusion criteria, 78% were adherent with the guidelines, including 10,918 who underwent cholecystectomy during the index hospitalization and 2,387 who underwent cholecystectomy within 30 days.
Among 3,705 patients non-adherent with the guidelines, the team noted that 1,213 had a cholecystectomy 16 months after the index hospitalization.
Guideline-adherent cholecystectomy resulted in fewer subsequent hospitalizations for acute and chronic pancreatitis as compared with non-adherence to the guidelines.
Dr Hutfless' team concludes, "Nearly 4 out of 5 patients underwent cholecystectomy for acute biliary pancreatitis in a timeframe, consistent with guidelines."
"Adherence resulted in a decrease in subsequent hospitalizations for both acute and chronic pancreatitis."
"However, the majority of non-adherent patients did not undergo a subsequent cholecystectomy."
"There may be factors that predict the need for immediate vs. delayed cholecystectomy."
