Cost-effectiveness of open versus laparoscopic repair for primary inguinal hernia.

A cost-effectiveness (CE) analysis was performed of Bassini versus laparoscopic repair for primary inguinal hernia. Incremental costs per 1-year recurrence-free patient were calculated for the societal and hospital perspective. From the hospital perspective, the incremental CE ratio of laparoscopic repair is 5.348 guilders. From the societal perspective, laparoscopic repair is both less costly and more effective than Bassini repair. Results were sensitive to assumptions about recurrence rates, laparoscopic operating time, and return to work. Laparoscopic repair should replace Bassini repair in order to benefit society. From the hospital perspective, the decision to accept laparoscopic repair depends on the willingness to pay.
