摘要

Background

Postoperative symptoms such as pain, burning, and itching are common following open excisional hemorrhoidectomy and are often associated with several factors, including wound healing. This study evaluated the efficacy of Propionibacterium extract gel (PeG) in promoting wound healing and reducing pain, burning, and itching compared to an ointment containing hyaluronic acid and silver sulfadiazine (HA-SSD).

Methods

In this multicenter, phase IV randomized controlled trial, patients undergoing open excisional hemorrhoidectomy were randomly assigned in a 1:1 ratio to receive PeG or HA-SSD. The primary outcome (wound healing) was evaluated on the basis of grade of epithelialization. Secondary outcomes (pain, burning, and itching) were assessed using a 10-point visual analogue scale at baseline and 10, 20, and 40 days postoperatively.

Results

Of the 119 screened patients, 64 (53.78%) received PeG and 55 (46.22%) received HA-SSD. The baseline characteristics were comparable. After 20 days, 46 (75.4%) of the PeG group patients had an epithelialization grade > 50% (vs n = 37, 72.6% of the HA-SSD group; p = 0.02). By day 40, complete wound healing occurred in 52 (85.3%) of the PeG group patients (vs n = 25, 52.1% of the HA-SSD group; p = 0.003). Both treatments reduced postoperative pain over time, with no significant between-group difference (p = 0.24). PeG demonstrated a superior reduction in burning (p = 0.02) and itching (p = 0.001). Patient satisfaction was higher with PeG (n = 45, 75% vs n = 9, 18.8% of the HA-SSD group, p < 0.001), with no reported adverse reactions.

Conclusions

PeG was more efficient than HA-SSD in promoting wound healing, alleviating burning and itching, and enhancing patient satisfaction following hemorrhoidectomy. This study supports the safety and effectiveness of PeG as a therapeutic option for postoperative management.
