Comparative study of internal anal competent seton combined with external anal fistula resection and suture or exclusion for the treatment of high anal fistula

Abstract

Objective To compare the effects of internal anal competent seton combined with external anal fistula resection and suture or exclusion on high anal fistula. Methods The curative effect of 65 cases underwent internal anal competent seton combined with external anal fistula resection and suture and 62 cases underwent internal anal competent seton combined with external anal fistula exclusion were comparative analyzed. Results The total efficiency of suture group was 90.77%, which was significantly higher than that of the exclusion group(70.97%), the difference was significant(P<0.05). The suture wound healing time and Wexner score of suture group were significantly lower than those of exclusion group (P<0.05). The recurrence rate of suture group(1.54%) was significantly lower than that of the exclusion group(9.68%), the difference was significant(P<0.05). Conclusions Internal anal competent seton combined with external anal fistula resection and suture in the treatment of high anal fistula significant can accelerate the healing of incision and improve the recovery of anal function.
