Most surgeons prefer fistulotomy by laying an open technique in treating different types of anal fistula. We used the radiofrequency fistulotomy procedure in 136 cases of various types of low anal fistulae in a one-year period. The patients were followed for 18 months. The average time for complete wound healing was 37 days and to resume routine 7 days. Delayed wound healing occurred in 7 patients. It failed completely in 2 patients and 3 patients lost to follow up. No patient had interference with continence. Radiofrequency fistulotomy method was effective with easy tissue excision and minimum bleeding. It permitted to be used in deep and difficult areas like the adjoining tracts. The failure rate was 3.7%. (Ref. 5.)
