Fistulotomy versus fistulotomy with marsupialization, a randomized controlled trial.

Abstract

Objective: To compare the efficacy of fistulotomy and fistulotomy with marsupialization in the management of simple anal fistula. Study Design: Randomized Controlled study. Setting: Department of Surgery, District Head Quarter Hospital, Mardan, Pakistan. Period: 1^st September 2021 to 31^st August 2022. Material & Methods: A total of 60 Patients coming to hospital with simple anal fistula were randomized into two equal groups. In group A, 30 patients were treated with fistulotomy, while in group B, 30 patients were treated with fistulotomy with marsupialization. The primary outcome was set as time required for complete wound healing. Secondary outcomes were operation time, postoperative pain, anal incontinence, incidence of recurrence and patient satisfaction. Results: The mean wound healing time after 6 weeks was shorter in group B in comparison to group A (4.7± 0.74 versus 6.4± 0.85 weeks; p=0.0001). There was no significant difference in mean operation time between Group B and Group A. The difference in mean pain score was also not statistically significant. There was no significant difference in the incidence of anal incontinence, incidence of recurrence and patient’s satisfaction among two groups. Conclusion: Fistulotomy with marsupialization is more effective procedure than fistulectomy alone in shape of early wound healing without increase in operation time and therefore can be taken as surgical procedure of choice for the simple anal fistula.
