Objective:To compare the clinical efficacy of procedure for prolapse and hemorrhoids(PPH)and improved circular hemorrhoidectomy(ICH)in circular mixed hemorrhoids treatment. Methods:Totally 80 patients with circular mixed hemorrhoids(Ⅲ-Ⅳ)were divided into two groups randomly with 40 patients in each group. The immediate and long-term outcomes

complications and cost were compared. Results:PPH group showed a reduction in blood loss

operating time

postoperative hospital stay

recovery time

the pain score

anus bulge

retention of urine and fecal incontinence

but an increase in cost compared with ICH group;the differences between the two groups were statistically significant(P<0.05). There was no statistically significant difference in the postoperative hemorrhage

anorectal stricture

overall efficiency rate and patient satisfaction(P >0.05). After 12 months of follow-up

four cases of recurrence in PPH group and one case in ICH group were observed

with no statistical difference between the two groups(P=0.356). Conclusion:PPH is a simple and safe way for the treatment of circular mixed hemorrhoids

with less trauma and complications and no higher recurrence rate

compared with improved circular hemorrhoidectomy. On the premise of cost control

PPH is worth clinical application.
