Non-abscessed Pilonidal Cyst

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.
