The A Clinical Study Of The Distal-vacuum-tight-line Treatment For High Anal Fistula

Objective:In order to seek for a new cutting seton to cure the high anal fistula and to protect the function of anal sphincter, we explored the distal cutting seton operation in the therapy for high anal fistula and investiaged its consequent effect on the function and morph of anus. This study provided clinical data for high anal fistula therapy.Methods:According to typical symptoms of high anal fistula,37cases were selected and randomly classified into therapy group and control group. The therapy group was treated with distal cutting seton and control group with traditional cutting seton, respectively. After treatments, the degree of anal pain, tight-line time, off-line time, curative time, the quantity of secretion, anal morph and the function of anal sphincter in two groups were observed and recorded. The patients were also tracked for three months after treatment and the ratio of recurrence was recorded. All results were quantified to scores according to the scoring criteria. With statistic analysis, differences of recurrence rate, curative time and post-operative function and morph of anus between the therapy group and control were compared.Results:No significant differences of curative rate, ratio of recurrence, tight-line time, off-line time and curative period between therapy group and control group were found. Meanwhile, post-operative pain and quantity of secretion between therapy group and control group were similar. However, through Wexner score and finger diagnose, there were significant differences of off-line time, the depth of anal coloboma at1st,2ndand3rd month after operation and rate of door lock analtaratogeina between therapy group and control. The distal cutting seton showed significantly superior to the traditional method in terms of before-mentioned parameters.Conclusion:The results in this study revealed that distal cutting seton to cure high anal fistula was similar to the traditional cutting seton in curative rate, recurrence ratio, tight-line time, off-line time, curative time, postoperative pain and quantity of wound secretion. But the distal cutting seton was superior to the traditional method in protecting anal function and decreasing anal malformation.
