Radiofrequency incision and lay open technique of pilonidal sinus (clinical practice paper on modified technique).

With the uncertainty as to the etiology and the complexities often encountered in its treatment, a pilonidal sinus has been considered as a tricky disease. Wide varieties of approaches are employed in dealing with this ailment ranging from a conservative treatment to an extensive surgical excision or repair. However, a method of simple lying open of pilonidal sinus is still considered as the favored one. We describe a modified approach to the procedure of incision and lying open the sinus tracts. This retrospective study describes 18 patients of chronic pilonidal sinus treated with a technique of radiofrequency surgery under local anesthesia. There were 12 males and 6 females within an age group ranging from 16 to 30. The patients were subjected to a follow-up for a period of 18 months. The patients were discharged on the same day of the procedure. Mean period off work was 7 days. The average healing time recorded was 67 days. Two wound complications in the form of premature closure of the skin edges were noted, requiring trimming of the edges. One of these two remained unhealed. At the last follow-up, no recurrence was found in the remaining 17 patients. In the era when the emphasis is on the criteria like minimum hospital stay, less postoperative pain, early resumption to work and a reduced recurrence rate, there is a future to the procedure of incision and lying open of the pilonidal sinuses by using the radiofrequency wave.
