Evaluation of the Healing of the Pilonidal Cyst After 1940 nm Laser Treatment

The aim of this study is to evaluate the extent to which the reduction of energy absorption that laser 1940 nm allows could improve the outcomes and postoperative results of the treatment of pilonidal cysts.

Treatment and study plan

pilonidal cyst laser surgery

Procedure

pilonidal cyst using 1940 nm laser treatment

Primary outcomes

  1. HEALING

    Time frame: 1 Month

    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.

Secondary outcomes

  1. Recidivism

    Time frame: 6 Month

    Recidivism is defined by: - The presence of persistent troubling symptoms 6 months after the surgery: suppuration, recurrent wound dehiscence, lack of healing despite care deemed optimal by the expert, reactivation/recurrence of abscesses. - The presence of a characteristic image on MRI if this examination has been carried out: subcutaneous collection, in hyper T2.
