Abstract

AIM: to assess late results of surgery for incomplete internal anal fistulas.PATIENTS AND METHODS: the prospective cohort study included 156 patients with in complete internal anal fistulas in 2014-2017.RESULTS: complete efficacy of the treatment was obtained in 132/147 (89.8%) patients, 106/117 (90.6%) revealed no anal incontinence (AI). Recurrence developed in 15/147 (10.2%) cases and 11/147 (7.5%) — anal incontinence. Newly developed incontinence was revealed in 7/117 (6.0%) patients: 6/117 (5.1%) had mild AI and 1/117 (0.9%) — moderate. The increase of AI degree showed 4/30 (13.3%) patients.CONCLUSION: a differentiated approach to anal fistulas surgery made it possible to minimize risk of incontinence and recurrence.
