Abstract: Objective To observe the clinical effects of elastic thread ligation stapler in the treatment of mixed hemorrhoids. Methods Eighty- seven patients with mixed hemorrhoids were divided into treatment group（48 cases）and control group（39 cases）. The treatment group was treated with elastic thread ligation stapler, while the control group was treated with Rubber ring ligation stapler. The clinical curative effects, pain degree, healing time, postoperative hemorrhage, edema, anal stenosis and other complications were observed and analyzed. Results The cure rate was 93.75%（45/48）in the treatment group, while the control group was 89.74%（35/39）. There was no significant difference in the overall efficacy between the two groups（P>0.05）. However, postoperative pain, postoperative edema, postoperative bleeding and wound healing time in the treatment group were significantly lower than those in the control group（P<0.05）. Moderate anal stenosis occurred in 3 patients in the treatment group at the third week of follow- up and 4 in control group, and the symptoms were improved after 3 to 5 anal expansions. Conclusion Elastic thread ligation treatment is superior to the rubber ring ligation stapler.

摘要： 目的　探讨弹力线套扎吻合器治疗混合痔的临床疗效。方法　将87例混合痔患者分成治疗组（48例）与对照组（39例），治疗组采用弹力线套扎吻合器治疗,对照组采用胶圈套扎吻合器治疗,观察两组的临床疗效、疼痛程度、愈合时间、术后出血、水肿、肛门狭窄等并发症。结果　1个月评价患者总体疗效后反映出,弹力线套扎吻合器治疗混合痔的治愈率为93.75%（45/48），采用胶圈套扎吻合器的治愈率为89.74%（35/39），两组患者总体疗效无明显统计学差异（P>0.05）。而且两组有效率均为百分之百，但治疗组术后疼痛、术后水肿的积分和术后出血量、创面愈合时间均明显低于对照组（P<0.05）。观察组有3例、对照组有4例出现中度肛门狭窄，经扩肛治疗后改善。结论　弹力线套扎治疗优于胶圈套扎吻合器。
