Research of results after anal sphincteroplasty surgery

Abstract

Introduction: Sphincteroplasty may be offered to symptomatic patients with a defined defect of the anal sphincter. In our country, there is no research on the results of anal sphincteroplasty surgery for anal sphincter muscle defects that became the basis for our research. In order to study the results of anal sphincteroplasty surgery in adults with fecal incontinence, the main objectives were to identify the main causes of anal sphincter muscle injuries, to study changes in the degree of fecal incontinence and quality of life, and to evaluate anorectal manometry. Materials and methods: In the study, we used a retrospective model to 52 patients who were operated anal sphincteroplasty between 2016 and 2019 at the Department of Coloproctology of First Central Hospital of Mongolia and statistical analysis are completed by STATA 12 software. Results: Preoperative fecal incontinence grade II n=1(1.92%), grade III n=48(92.31%), and grade IV n=3(5.77%) cases were reported in patients who were operated anal sphincteroplasty. Postoperative degree of fecal incontinence changed to grade I n=3(3.85%), grade II n=23(44.23%), and grade III n=27(5.77%). The mean of the preoperative Park’s score was 3.03±0.27, and the following improved to 2.48±0.57. Quality of life scores (FIQLS) improved by an average of 19.7%. The mean squeeze pressure was 89.2±17.3 mmHg, which was 10.8% lower than the average for a healthy person. The resting pressure was 44.5±11.9 mmHg, which is normal. An average rectal volume of 144.5±24.5 ml is normal. Conclusion: Short-term outcomes of anal sphincteroplasty are good, but are likely to decline in the medium to long term. Postoperative outcomes in patients over 50 years of age are lower than in other age groups.
