Abstract: Objective To observe the clinical effect of mini incision and suspension fixation on severe circular mixed hemorrhoids. Methods A total of 144 patients with severe circular mixed hemorrhoids were randomly divided into a control group and a treatment group. The control group was treated with traditional external stripping and internal ligation, while the treatment group was treated with mini incision and suspension fixation. Operation effect, postoperative pain, edema, bleeding, anal stenosis, and wound healing time were compared between the two groups. Results The curative rate of mini incision and suspension fixation was similar to that of traditional external stripping and internal ligation, but there were significant differences in postoperative pain,bleeding, edema, anal stenosis, and wound healing time between the two groups （P<0.05）. Conclusion Mini incision and suspension fixation is effective in the treatment of severe circular mixed hemorrhoids, with small wound, little pain, less bleeding, a low edema rate,short wound healing time, and a low rate of anal stenosis.
