Insufficiency of the anal sphinter in women

Aim. To analyze and assess the clinical course and changes under instrumental-functional examination (MRI) in the muscles of the obturator apparatus of the rectum in women with anal sphincter insufficiency (ASI).Material and methods. Clinical and instrumental research methods, as well as modern scales for assessing ASI (Wexner score scale), were used in the current study.Results and discussion. The study showed that 110 out of 228 patients with anal sphincter deficiency showed only an organic form of ASI, and 118 (51.8%) had a mixed form (organic and functional). This study shows that the degree of postpartum perineal rupture depends on the factors producing the damage to the pelvic floor muscles.Conclusion. Analysis of the clinical course of ASI in women showed that gender-related factors in 51.8% of cases contributed to the development of a mixed form of the disease. Functional research methods showed that along with the external and internal sphincters of the rectum, the pubo-rectal muscle is damaged in patients with ASI, which should be taken into account when choosing a treatment strategy for the mixed form of ASI.
