To investigate the clinical effect and outcome of traditional hemorrhoidectomy and procedures for prolapse and hemorrhoid (PPH) for the treatment of grades III and IV hemorrhoids.We retrospectively reviewed 1003 grades III and IV hemorrhoid patients who presented to our hospital. A total of 585 patients underwent PPH, and 418 patients underwent hemorrhoidectomy. The outcomes were 1-year recurrence, postoperative complications, surgery-related complications, and indicators.No significant difference between the 2 treatment groups regarding patient demographics. All patients underwent more than 12 months of postoperative follow-up. No significant difference between the 2 treatment groups in 1-year recurrence. PPH can markedly improve anal pain, postoperative bleeding, difficult urination, and postoperative resting anal pressure. The operative blood loss, operative time, wound healing time, and wound infection rates were decreased significantly in the PPH group compared with the traditional hemorrhoidectomy group.Our data suggest that PPH is useful and safe for grades III and IV hemorrhoids. It can reduce postoperative and surgery-related complications. However, this was a single-hospital retrospective study. Therefore, well-designed, multicenter, randomized controlled trials are needed to evaluate the value of PPH for grades III and IV hemorrhoids.Abbreviations: PPH = procedures for prolapse and hemorrhoid, RAP = resting anal pressure.
