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.
