经括约肌间瘘管结扎术治疗高位单纯性肛瘘的前瞻性临床对比研究

目的探索经括约肌间瘘管结扎术治疗高位单纯性肛瘘的临床疗效及安全性。方法前瞻性收集2015年3月至2017年12月期间笔者所在医院科室收治的72例确诊为高位单纯性肛瘘的患者,按随机数字表法并结合患者意愿分为经括约肌间瘘管结扎术组(试验组,32例)和高位肛瘘低切高挂术组(对照组,40例),比较2组患者的手术效果和术后6个月时的括约肌生理功能。结果与对照组相比,试验组患者的术后疼痛持续时间短,术后创面愈合时间短,治愈率高,复发率低,初始感觉阈值低,肛管静息压高,肛管高压带长度长,差异均有统计学意义(P<0.05);但2组患者的手术时间、肛管最大收缩压和直肠静息压比较差异均无统计学意义(P>0.05),表明试验组的肛门生理功能恢复较好。结论经括约肌间瘘管结扎术治疗高位单纯性肛瘘的效果明显,术式安全可靠,可在临床中推广应用。

A prospectively clinical comparative study of ligation of intersphincteric fistula tract in treatment of high simple anal fistula

Objective To explore the clinical efficacy and safety of ligation of intersphincteric fistula tract in the treatment of high simple anal fistula. Methods A prospective collection of 72 patients diagnosed with high simple anal fistula, who admitted to the department of the author’s hospital between March 2015 and December 2017 was performed, and then the patients were divided into two groups according to the random number table method combined with the patients’ wishes: the ligation of intersphincteric fistula tract group(experimental group, 32 cases)and the low incision and high hanging group(control group, 40 cases). Comparison of indexes on the operative effect and physiological function of the sphincter in six months after operation was performed. Results Compared with the control group, the patients in the experimental group had short postoperative pain duration, short postoperative wound healing time, high cure rate, low recurrence rate, low initial sensory threshold, high anal resting pressure, and long anal high pressure band length, with statistically significant differences(P<0.05). However, there was no statistically significant difference between the two groups in the operation time, anal maximal contractive pressure, and rectal resting pressure(P>0.05). The results suggested that the physiological function of anus in the experimental group recovered well.Conclusion The ligation of intersphincteric fistula tract is a safe and reliable method in the treatment of high simple anal fistula, which can be widely used in the clinic.
