Observation of effect of sphincteric fistula ligation in the treatment of complex anal fistula / 中国基层医药

ABSTRACT

Objective To explore the therapeutic effect of sphincteric fistula ligation in the treatment of complex anal fistula. Methods From August 2016 to April 2017,66 patients with complicated anal fistula in the People's Hospital of Liulin County were selected as in the study. They were divided into two groups according to the principle of average and complete randomization, with 33 cases in each group. The control group was treated by hanging line. The treatment group was treated with ligation of sphincter fistula. The clinical effect,operation condition, postoperative pain and adverse events were observed in the two groups. Results The total effective rate of the observation group was 93. 94％ ,which was higher than 75. 76％ of the control group (χ2 = 4. 24,P < 0. 05). In the observation group,the wound healing time,the length of hospital stay and the postoperative pain score were better than those in the control group[(15. 69 ± 1. 28)d vs. (19. 47 ± 1. 93)d,(8. 93 ± 0. 71)d vs. (12. 61 ± 1. 08)d,(2. 29 ± 0. 56)points vs. (4. 29 ± 0. 74)points,t = 9. 38,16. 36,12. 38,all P < 0. 05]. The incidence rate of adverse events in the observation group was lower than that in the control group,but the difference was not statistically significant (9. 09％ vs. 21. 21％ ,χ2 = 1. 89,P > 0. 05),and the recurrence rate of the observation group was significantly lower than that of the control group(3. 03％ vs. 21. 21％ ,χ2 = 5. 12,P < 0. 05). Conclusion Sphincteric fistula ligation in the treatment of complex anal fistula can effectively control the disease,promote wound healing,and has a good prognosis.
