Abstract

Objectives: We studied the outcome of cutting seton in the treatment of a high transsphincteric anal fistula in Sudan.

Methods: This was a prospective study of high transsphincteric anal fistulas at Kassala Police Hospital, Sudan, over the course of 24 months (2016-2017). The main outcomes measured were recurrence, incontinence and primary healing rates.

Results: The cases of 72 patients treated with cutting seton for high transsphincteric fistula were analysed, with 50 (70%) of the patients being male and 22 (30%) being female. Forty-eight (66.7%) patients required two sessions of seton tightening with a duration of seton treatment of 30 days and 24 (33.3%) patients required three sessions with a duration of seton treatment of 45 days. Only one patient (1.4%) had flatus incontinence. Three (4.2%) patients had minimal bleeding from the seton site and two (2.8%) patients experienced fistula recurrence. Twenty-six (36%) patients achieved complete healing within 30 days, while 36 (54.3%) patients healed within 60 days. The remaining seven (9.7%) patients healed after 60 days. Chronic pain was reported by two (2.8%) patients after complete healing.

Conclusion: In Sudan, cutting seton remains relevant, as it produces minimal incontinence with a low recurrence rate in high transsphincteric fistula treatment.
