The Clinical Research On The Effect Of Therapy For High Anal Fistula With Improved Cutting Seton

OBJECTIVE:The anal fistula is a familiar anorectal disease, but the therapy of the high anal fistula is very difficult.To seek for the internal orifice is the key of the cure of the disease. Bases of the sphincter cutting seton in the high anal fistula,we use the improved cutting seton to cure the high anal fistula,comparing with the traditional cutting seton randomly. We will elect the better one of protecting the anal funetion in the sphincter cutting seton of the high anal fistula.METHODS:30 patients were divided into therapy group and control group randomly. There are 15 patients in therapy group and 15 patients in control group. The therapy group is treated with the improved cutting seton and the control group with the traditional cutting seton. According to the project, we observe the two groups after operation, and then investigate for three months to half a year. Using these statistic data, we can study the difference in the curative effect,the period of treatment the rate of recurrence,the function of the anal sphincter,the degree of the anal pain,the quantity of the secretion and so on.RESULT:No difference in the curative effect,the period of treatment,the ratio of recurrence,the degree of the anal pain,the quantity of the secretion between the two groups(P>0.05).Through the Wexner score,the finger diagnose, there is a significant difference in the function of the anal sphincter after operation(P<0.05), and in the depth of the anal coloboma, there is a significant difference of off-line,1st month,2nd month and 3rd month after operation (P<0.05). In the rate of the door lock anal taratogenia, there is a significant difference of 3rd month after operation(P<0.05).CONCLUSION:The study indicates that the improved cutting seton to cure high anal fistula is not superior to the control group in the curative effect,the period of treatment the ratio of recurrence,the degree of the anal pain,the quantity of the secretion and so on. But the improved cutting seton is dominant in protecting the function of the anal sphincter and cutting down the influence of the anal-morph with cutting seton.
