Objective: To perform a cost-effectiveness analysis to examine the utility and effectiveness of OS performed at the time of elective cholecystectomy [laparoscopic cholecystectomy (LAP-CHOL)]. Summary Background Data: OS has been adopted as a strategy to reduce the risk of ovarian cancer in women undergoing hysterectomy and tubal sterilization, although the procedure is rarely performed as a risk reducing strategy during other abdominopelvic procedures. Methods: A decision model was created to examine women 40, 50, and 60 years of age undergoing LAP-CHOL with or without OS. The lifetime risk of ovarian cancer was assumed to be 1.17%, 1.09%, and 0.92% for women age 40, 50, and 60 years, respectively. OS was estimated to provide a 65% reduction in the risk of ovarian cancer and to require 30 additional minutes of operative time. We estimated the cost, quality-adjusted life-years, ovarian cancer cases and deaths prevented with OS. Results: The additional cost of OS at LAP-CHOL ranged from $1898 to 1978. In a cohort of 5000 women, OS reduced the number of ovarian cancer cases by 39, 36, and 30 cases and deaths by 12, 14, and 16 in the age 40–, 50–, and 60-year-old cohorts, respectively. OS during LAP-CHOL was cost-effective, with incremental cost-effectiveness ratio of $11,162 to 26,463 in the 3 age models. In a probabilistic sensitivity analysis, incremental cost-effectiveness ratio for OS were less than $100,000 per quality-adjusted life-years in 90.5% or more of 1000 simulations. Conclusions: OS at the time of LAP-CHOL may be a cost-effective strategy to prevent ovarian cancer among average risk women.
