Functional gallbladder disease: Operative trends and short-term outcomes.

Background: Due to increasing rates of functional gallbladder disease (FGBD), we used national data to compare rates, patient characteristics, and outcomes of cholecystectomy for FGBD with the more defined diagnosis of biliary colic.

Methods: The American College of Surgeons National Surgical Quality Improvement Program was reviewed for elective cholecystectomies from 2005-2013. The proportion of cholecystectomies performed for FGBD was assessed over time using a 2-sided Cochran-Armitage test for trend.
