Objective To evaluate circumferential mucosectomy for the treatment of prolapsed hemorrhoids. Methods Ten patients with Ⅲ or Ⅳ degree of circular prolapsed hemorrhoids were operated on with circumferential mucosectomy using circular stapler. The mean age was 65 years old with hemorrhoids history of 3～25 years. Results Hemorrhoids in 8 of the 10 patients disappeared immediately after operation and 2 disappeared on the second day postoperatively. 3 patients complained local pain and 6 patients suffered from temporary urine retention after operation. No significant edema or bleeding ensued. The mean postoperative hospital stay was 4 days. No recurrence developed at an averaged 2 months′ follow up. Conclusion The new technique provides a significantly less painful choice of treatment for severely prolapsed circular hemorrhoids. However, the long-term outcome remains to be identified.
