Patient who underwent surgery for a pilonidal cyst using 1940 nm laser treatment

pilonidal cyst using 1940 nm laser treatment

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.

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.
