Background: Fecal incontinence is the inability to control your bowel movements, causing stool (feces) to leak unexpectedly from the rectum. Materials and methods: The article presents the experience gained in treating 56 patients with anal incontinence after surgery for anorectal malformations, Hirschsprung’s disease, for the period 1996-2006. and studying long-term results covering the period from 2007 to 2019. The age of children ranged from 3 months. up to 14 years old. Results: In patients of the main group clinically there was a deficiency (fecal incontinence) of the sphincter of 1.2.3 degrees (respectively, in 10.19.7 children). When using the point scale, these numbers changed (respectively in 4.13.19 children). This can be explained by the fact that a clinical assessment of the degree of sphincter insufficiency takes into account only how much the patient is able to retain intestinal contents, and 7 points are taken into account when scoring. Conclusion: The analysis of clinical material shows that the anal incontinence in children after operations can be caused by damage to the sphincter apparatus or a violation of the anatomical and topographic ratios of the rectum due to its improper reduction in perineal or abdominal perineal proctoplasty, as well as congenital anomalies with side of the distal spine, which is an independent nosological form, or a concomitant pathology, exacerbating functional disorders in anorectal anomalies, which subsequently negatively affect the results of corrective operations.
