A new surgical approach for pilonidal sinus disease: "de-epithelialization technique''

In the treatment of pilonidal sinus disease different approaches are used such as conservative treatment and fasciocutaneous rotation flap. The aim of this study was to evaluate the efficacy of "de-epithelialization technique" as a new approach in pilonidal sinus disease treatment.

Forty pilonidal sinus disease patients treated with de-epithelialization method were evaluated retrospectively. Patient age, gender, body mass index, wound healing time, visual analog scale scores, operation times, hospital stay duration, drain removal time, cosmetic satisfaction rates, complications, and recurrence rates were evaluated.

The numbers of male and female patients in this study were 39 and 1, respectively. The median age of the patients was 25 years and the mean BMI was 26.6. The mean operating time was 43 min, and all patients were discharged 5 h after the operation. Wound healing time varied from 10 to 20 days. Median follow-up period was 9 months (4-17 months). One patient with high body mass index suffered from partial wound separation. No other complications such as infections and fluid collections (hematoma and seromas) were observed. Maximum cosmetic satisfaction rate was 90% (n=36), and no patient had a recurrence during the follow-up period.

"De-epithelialization" may be considered as a complementary and/or alternative approach to other surgical techniques such as primary closure, rhomboid excision, and Limberg flap in the treatment of pilonidal sinus disease, with acceptable cosmesis and recurrence rates.
