Core Tip
Core tip: Hemorrhoidectomy, e.g., the ligation and excision method, is still the gold standard surgical technique for hemorrhoids. All of the classical surgical techniques for hemorrhoids are fundamentally based on the resectioning of the hemorrhoids, which can result in anal stenosis. We developed the anal cushion lifting method, in which the prolapsed anal cushion is restored to its original position, as a way of preventing various postoperative complications. We recruited 127 patients and conducted a prospective clinical study. By the end of the study, none of the patients had suffered anal stenosis or persistent anal pain.
