ABSTRACT
Laser surgery, a minimally invasive procedure for the definitive approach to pilonidal disease (PD), has been frequently studied in recent years. This study aims to describe a new pilonidotomy method using minimal laser energy and evaluate its initial results. This is a retrospective multicenter study. We included 47 consecutive patients who underwent 50 "minimal energy pilonidotomies (MELPi)" between 2019 and 2023 in four centers in Brazil. Age, BMI, gender, smoking, diabetes, Guner classification, duration of illness, energy, hospitalization time, complications, recurrence, wound closure, pain, and return to activities were analyzed. The median age was 27; 61.7% were men, and 38.3% were women. The median BMI was 25.7. Smoking was evident in 14.9%, and diabetes in 2.1%. The average duration of the disease was 3 years. Most operations (36%) were performed on stage R disease. The median hospitalization time was 6 h, and the median healing time was 15 days. The average energy used in procedures was 433 J. The median postoperative pain was 2. Secretion occurred in 14% on the 60th day. Complications (cellulitis) occurred in 4% of cases. The median time to return to work was 7 days. The average following time was 12 months; recurrence occurred in 5 (10%)-in 3 patients, a second MELPi procedure was performed and was effective. MELPi shows promising initial results: low pain, low complication rates, and a fast activity return. It is a good option in recidivate cases and can be done more than once if necessary.
