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.
Patients who did not object to the collection of their data
Patients who underwent surgery for a pilonidal cyst using 1940 nm laser treatment
Patients with a history of pilonidal cyst surgery
Patients who underwent emergency surgery for an abscess
Patients already included in another therapeutic study protocol
patients treated with laser 1940 nm for a pilonidal cyst.
Cohort
Prospective
pilonidal cyst laser surgery
Procedure/Surgerypilonidal cyst using 1940 nm laser treatment
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.
Recidivism
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.
