量化传统挂线疗法对高位肛瘘术后肛门功能影响的研究

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)%,...

Change of anal function after quantified cutting seton therapy for high anal fistula

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.
