Cost-utility Analysis of the Use of a Laser Fiber in the Management of Non-abscessed Pilonidal Cyst

Overview

This multicenter, prospective, randomized, open-label trial compares laser fiber treatment with conventional surgery in adults with non-abscessed pilonidal cyst. The main objective is to evaluate the incremental cost-utility ratio of laser fiber versus conventional surgery over 12 months from a societal perspective. Secondary objectives include 3-month cost-utility, healing time, closure at 3 months, recurrence at 12 months, postoperative complications, treatment parameters, postoperative pain, and duration of sick leave.

Pilonidal cyst surgery is common in France and mainly affects young adults. Conventional surgery is effective but may be associated with longer healing time, prolonged dressing use, and work absence. Laser fiber treatment is a minimally invasive alternative used in France since 2019 and may reduce healing time and postoperative burden; however, prospective randomized comparative medico-economic evidence is lacking. This national multicenter study randomizes adults with non-abscessed pilonidal cyst to laser fiber treatment or conventional surgery in a 1:1 ratio. The primary endpoint is the incremental cost-utility ratio over 12 months, using total costs and utility derived from EQ-5D-5L (QALY). Participants are followed from baseline to month 12, with assessments at J8, J15, M3, M6, M9, and M12.
