EVALUATION OF ETIOLOGY AND SURGICAL OUTCOMES OF COMPLETE ANAL SPHINCTER INJURIES IN IMAM KHOMEINI MEDICAL CENTER, URMIA, IRAN

Anal sphincter damage is a clinical condition that causes fecal incontinence and can severely disrupt a person's quality of life. Overlap sphincteroplasty is the most commonly referred surgical procedure for ASI repair. The aim of this study was to investigate the etiology and surgical outcomes of the patients with complete anal sphincter injury (ASI) in Imam Khomeini Medical Training Center, Urmia, Iran.

In this descriptive-analytical study, the study population included all cases of ASI surgery in the surgery department of Imam Khomeini Hospital in Urmia from March 2018 to March 2022 were investigated. Data has been analyzed by SPSS version 20 software using analysis of variance (ANOVA) and chi-square tests. A significance level of 0.05 was considered significant.

A total of 45 patients with ASI were selected. The results showed that there was a significant difference between severity and type of fecal incontinence (gas, liquid, solid) before and after the surgery in the patients with ASI (P<0.001). Also, according to the Wexner score, the severity of fecal incontinence before surgery (16.9 ± 3.7) was higher than it after surgery (4.1 ± 3.6), which indicates its reduction after surgery (P>0.05). Also, according to the Wexner score, the average improvement in incontinence was 14 ± 3.6 in women and 11.8 ± 4.2 in men no significant relationship, indicating that gender had no effect on the improvement of incontinence (P>0.05). Also, the results showed that the age of the patients had no effect on the recovery of fecal incontinence (P>0.05). However, the recovery rate of fecal incontinence in trauma patients was higher than the patients who underwent surgery (P<0.05).

The severity of fecal incontinence after surgery has decreased compared to it before the surgery, and the recovery rate of incontinence in childbirth and trauma patients was higher than it in surgical patients.
