改良经括约肌间瘘管结扎术治疗经括约肌型肛瘘的临床疗效观察

Clinical observation of modified ligation of the sphincteric fistula tract in the treatment of sphincteric perianal fistula

目的探讨改良经括约肌间瘘管结扎术(ligation of intersphincteric fistula tract,LIFT)治疗经括约肌型肛瘘的临床疗效。方法选取江门市中心医院胃肠外科100例经括约肌型肛瘘患者,随机分为观察组(n=50)及对照组(n=50),分别行改良LIFT手术、常规肛瘘切除及挂线术。比较两组病例手术耗时、手术出血量、术后疼痛持续时间、住院时间、切口愈合时间、肛门功能、肛门形态及肛瘘复发率。结果观察组患者在手术耗时、手术出血量、术后疼痛持续时间、切口愈合时间、肛门功能及肛门形态方面,结果均优于对照组,差异具有显著性(P<0.05),但两组患者住院时间及肛瘘复发率,差异无显著性(P>0.05)。结论对比常规肛瘘切除及挂线术,改良LIFT术治疗经括约肌型肛瘘具有良好的临床效果。

Objective To investigate the clinical effect of modified ligation of the sphincteric fistula tract(LIFT)in the treatment of sphincter anal fistula.Methods According to the random number table,patients with perianal horseshoe abscess were randomly divided into two groups,the experimental group(by modified LIFT)50 cases and the control group(by classic operation)50 cases.The operation time,intraoperative blood loss,duration of the postoperative pain,hospital stay,healing time of surgical incision,anal function,anal morphology and recurrence rate of two groups were recorded and analyzed.Results The observation group was better than the control group in operation time,operation blood loss,postoperative pain duration,incision healing time,anal function and anal morphology,the difference was significant(P<0.05),but there was no significant difference in hospital stay and anal fistula recurrence rate between the two groups(P>0.05).Conclusion Compared with the classic operation,it has good clinical effect to treat sphincteric perianal fistula through modified LIFT.
