Clinical efficacy of modified single pouch four-point traction procedure for PPH in treatment of circular mixed hemorrhoids

Abstract

Objective To observe the clinical efficacy of modified single pouch four-point traction procedure for prolapse and hemorrhoids （PPH） in the treatment of circular mixed hemorrhoids. Methods A total of 86 patients with circular mixed hemorrhoids were recruited and randomly divided into the experimental group （n = 43） and control group （n = 43）. In the control group, traditional single pouch single-point traction procedure for PPH was adopted, and modified single pouch four-point traction procedure for PPH was delivered in the experimental group. Surgical conditions, clinical efficacy, visual analogue scale （VAS） score, postoperative complications, and recurrence rate within postoperative one year were statistically compared between two groups. Results The width of the mucosal ring, the uniformity rate of the mucosal ring, and the retraction rate of hemorrhoids in the experimental group were significantly higher than those in the control group （all P < 0.05）. The cure rate in the experimental group was significantly higher than that of the control group （98% vs. 86%, P < 0.05）. In two groups, the VAS scores after surgery were significantly decreased over time, and the degree of decline in the experimental group was more pronounced than that in the control group （both P < 0.05）. The incidence of postoperative complications, such as postoperative bleeding, anal stenosis, and anal bulging, and the recurrence rate within postoperative one year did not significantly differ between two groups （all P > 0.05）. Conclusion The modified single pouch four-point traction procedure for PPH can resect the mucosal ring in a more uniform pattern, yield higher cure rate and better safety compared with traditional technique.
