摘要
目的观察高位肛瘘术中不同程度挂线后肛门功能改变情况。方法本研究共观察病例45例，分为3组，每组15例，均行低位切开高位挂线手术，以挂线勒割肌束收紧长度为分组观察依据。结果肛管压力下降以静息压为著，1／4组下降为（15．09±2．91）％，1／3组为（24．77±1．15）％，1／2组为（33．32±1．91）％，差异有统计学意义；Wexner评分，出现偶尔的气体控制不佳或肛门渗液，约为14％。结论1／4组及1／3组是较理想的挂线方案，对肛门功能保护较好。本研究设计的带刻度的橡皮筋应用于挂线疗法操作简便，安全可靠，值得推广使用。
Objective To observe the change of anal function after cutting seton therapy of different levels for high anal fistula. Methods Forty - five cases were randomized into three groups with regard to the tightness of the seton （n = 15 each）. All patients were given the traditional low - position incision and high - position cutting seton therapy. Results Postoperative anal pressure was declined, especially the resting pressure ,to（ 15.09 ± 2.91 ）% of original anal resting pressures in the 1/4 experimental group, and to（24.77 ± 1.15）% in the 1/3 experimental group,and to（33.32± 1.91 ）% in the 1/2 experimental group（ P 〈 0.05 ）. Based on Wexner Score,the rate of failure of gas control and anal exudation was about 14%. Conclusion Tightening the seton to 1/4 or 1/3 of the tissues＇ girth is optimal,which could protect the function of the anal sphincter. The scaling rubber band designed in our study is easy, safe and effective for cutting seton therapy.
