ABSTRACT

Objective To investigate the clinical effect of modified seton therapy with counterparts drainage on high anal fistula.Methods One hundred and forty-four patients with high anal fistula were randomly assigned to the observed group (modified seton therapy with counterparts drainage,74 cases) and the control group (the traditional high hanging line therapy,70 cases).The clinical efficacy,visual analogue scale (VAS),Wexner incontinence score,fecal incontinence quality of life index (FIQLI) score were compared.Results Observed group were cured with 40 cases,improved with 27 cases,ineffective with 7 cases,control group were cured with 25 cases,improved with 43 cases,ineffective with 2 cases,difference between two groups was statistically significant (P ＜ 0.01).The healing time in observed group was significantly shorter than that in control group(P＜ 0.01).The VAS after therapy 1,7 d in observed group was significantly lower than that in control group (P ＜ 0.05).The Wexner incontinence score,FIQLI score before therapy was no significant difference between two groups (P ＞0.05).The Wexner incontinence score,FIQLI-lifestyle score,FIQLI-depression/self-perception score,FIQLI-distress score after therapy 3 months in observed group was significantly higher than that before therapy and control group after therapy 3 months (P ＜ 0.05),there was no significant difference Wexner incontinence score and FIQLI score before therapy compared with therapy 3 months in control group (P ＞ 0.05).Conclusions Modified seton therapy with counterparts drainage may be a valid treatment for high anal fistula.The successful outcome is associated with significant improvement in quality of life.
