Laying open (deroofing) and curettage under local anesthesia for pilonidal disease: An outpatient procedure

To test the efficacy of lay open (deroofing, not excision) with curettage under local anesthesia (LOCULA) for pilonidal sinus as an outpatient procedure.

LOCULA procedure was done for all types of pilonidal disease. The primary outcome measure was cure rate. The secondary outcome measures were hospital stay, operating time, return to work, healing time and complication rate.

Thirty-three (M/F-30/3, mean age-23.4 ± 5.8 years) consecutive patients were operated and followed for 24 mo (6-46 mo). Eleven were pilonidal abscess and 22 were chronic pilonidal disease. Six had recurrent disease. Operating time and the hospital stay was 22.3 ± 5.6 min and 63.8 ± 22.3 min respectively. The patients could resume normal work in 4.3 ± 3.2 d and the healing time was 42.9 ± 8.1 d. Thirty (93.8%) patients had complete resolution of the disease and two (6.2%) had a recurrence. Both the recurrences happened in patients who had complete healing but ignored the prescribed recommendations. One out of these got cured after getting operated again with the same procedure. Thus the overall success rate of this procedure was 96.9%.

Lay open (deroofing) with curettage procedure under local anesthesia is an effective procedure to treat both simple and complicated pilonidal sinus and abscess. It is a simple procedure, has a high cure rate (up to 97%), doesn't require admission and is associated with minimal morbidity and scarring. Considering the distinct advantages, this procedure has the potential to become the first line procedure for treating pilonidal disease.
