Abstract：Objective: To observe the effects of sphincter-retaining thread-drawing therapy and fistulectomy on the short-term efficacy, healing time and complications of patients with complex anal fistula. Methods: 90 patients with complex anal fistula were divided into sphincter-retaining thread-drawing therapy group (study group, n=45) and fistulectomy group (control group, n=45). The operation situation was observed, and the short-term efficacy was evaluated at 1 month after operation. The postoperative healing and anal function improvement 【anal incontinence score (Wexner)】 were compared between the two groups, and the incidence rate of complications was recorded. Results: The operation situation in study group was better than that in control group (P<0.05). There was no significant difference in the total effective rate between the two groups (P>0.05), and the good improvement rate in study group was higher than that in control group (P<0.05). The wound area, wound healing time and incidence rate of complications in study group were smaller than those in control group (P<0.05). There was no significant difference in the Wexner score between the two groups before operation (P>0.05), and the difference of Wexner score before and after operation in study group was greater than that in control group (P<0.05). Conclusions: Compared with fistulectomy, sphincter-retaining thread-drawing therapy for complex anal fistula can improve the operation situation, enhance the efficacy, and promote wound healing and anal function recovery, and it has good safety.
