A Comparative Study on Efficacy and Safety of Modified Partial Stapled Hemorrhoidopexy versus that of Conventional Hemorrhoidectomy: A Prospective Randomized Controlled Trial

Abstract

Purpose The long-term outcomes and efficacy of partial stapled hemorrhoidopexy (PSH) compared with those of conventional hemorrhoidectomy (CH) are not well understood. This study aimed to introduce a modified PSH and compare its clinical efficacy and safety with those of CH. Methods A prospective randomized controlled trial was conducted. This study was performed at a single hospital and involved six colorectal surgeons. In total, 110 patients were enrolled between July 2019 and September 2020. Patients were randomly assigned to undergo either PSH (group 1, n = 55) or CH (group 2, n = 55). Results The duration of analgesia requirement was shorter in the PSH group than that required in the CH group, although the difference was not statistically significant (P = 0.096). However, the laxative requirement duration (P < 0.01), return to work (P < 0.01), satisfaction score (P < 0.01), and incontinence score (P = 0.014) were significantly better in the PSH group. The average and peak postoperative pain scores were significantly lower in the PSH group during the first 15 days after surgery. The overall complication rate in both groups was 9.1%, with no significant difference between the groups (P = 0.867). Conclusions Modified PSH demonstrated better improvement in symptoms, lower pain scores, and greater patient satisfaction than CH. Therefore, this surgical technique appears to be a safe and effective alternative for CH.
