Outcome Measures

Primary Outcomes (1)

  • HEALING

    The main objective is to evaluate the healing rate of the pilonidal sinus one month after treatment with Er-YAG laser 1940 nm. Wound healing at one month, defined by the absence of a dressing, is the main evaluation criterion.

    1 Month

Secondary Outcomes (1)

  • Recidivism

    6 Month
