经括约肌间瘘管结扎术治疗经括约肌肛瘘的临床研究

Ligation of Intersphincter Fistula Tract in the Treatment of Complex Anal Fistula ： Clinical Research

为观察经括约肌间瘘管结扎术（LIFT）与肛瘘切开挂线术治疗经括约肌肛瘘的临床疗效及并发症，将60例肛瘘患者随机分为治疗组（经括约肌间瘘管结扎术）与对照组（肛瘘切开挂线术）各30例，观察2组患者治疗总有效率、手术时间、住院时间、术后疼痛程度及创面愈合时间，并测定2组患者治疗前后及随访终点的肛门功能评分情况。结果显示，2组患者治疗总有效率比较差异无统计学意义（P〉0．05）I2组患者在住院时间、术后疼痛程度方面治疗组明显优于对照组，但对照组的手术时间则明显短于治疗组（P〈0．05）;治疗组创面愈合时间明显短于对照组（P〈0．05）；随访终点2组患者肛门功能评分治疗组优于对照组（P〈0．05）。结果表明，经括约肌间瘘管结扎术与肛瘘切开挂线术治疗经括约肌肛瘘临床疗效无显著性差异，但经括约肌间瘘管结扎术具有住院时间短、术后疼痛程度轻及创面愈合时间短的优势。比肛瘘切开挂线术具有更大的优越·眭。

This study was to investigate the clinical effects of ligation of intersphincter fistula tract（LIFT） and incision＆ thread-drawing procedure of anal fistula in the treatment of intersphincter anal fistula, and their complication,randomly divided 60 patients into treatment group（treated with LIFT） and control one （treated with incision ＆ thread-drawing procedure）, 30 cases for each;then, total effective rate, operative time, hospitalization time, postoperative pain degree and healing time of wound-surface in two groups were observed,as well the score on anal function before and after surgery, and at the end of follow-up were measured.As results, in total effective rate there was no statistical difference between both groups（ P 〉 0.05） ,in hospitalization time,postoperative pain degree the former was significantly superior to the latter, but operative time of the latter was significantly shorter than that of the former（ P 〈0,05）, the time for wound-surface healing of the former was significantly shorter than that of the latter（ P 〈 0.05）tin the score on anal function at the end of follow-up the former was superior to the latter（ P 〈0.05）.Results show that in clinical effects there is no significant difference between two procedures, hut LIFT has such merits as shorter hospitalization time, milder pain degree after surgery, and shorter time for wound-surface healing compared with incision ＆ thread-drawing procedure,
