Brief summary

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.

Inclusion criteria

* Patients who did not object to the collection of their data * Patients who underwent surgery for a pilonidal cyst using 1940 nm laser treatment

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
HEALING1 MonthThe 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

MeasureTime frameDescription
Recidivism6 MonthRecidivism 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.
