Prospective Randomized Clinical Trial Comparing Two Different Circular Staplers for Mucosectomy in the Treatment of Hemorrhoids

Abstract
The main objections against circular stapled mucosectomy have been anal pain and rectal bleeding during the surgical procedure or in the immediate postoperative follow-up. To avoid these consequences, a new stapler (PPH33-03) has been developed. The aim of this trial was to compare the intraoperative and short-term postoperative morbidity of stapled mucosectomy with PPH33-01 versus PPH33-03 in the treatment of hemorrhoids.
