Suprahemorrhoidal mucosal ligation

In 1975, Thomson proposed the theory of inferior displacement of anal cushion and gradually became recognized. With the increasing understanding of the nature and mechanism of hemorrhoids, the treatment of hemorrhoids has undergone great changes in concept and method. In April 2000, the Anorectal Surgery Group of the Chinese Medical Association defined the concept of hemorrhoids: “Hemorrhoids are localized masses formed by pathological hypertrophy and displacement of the anal cushion and stagnation of blood flow in the perianal subcutaneous vascular plexus”. New methods of treating hemorrhoids based on this concept are constantly being developed. There is also a convergence in the understanding of surgical treatment of hemorrhoids. The aim of treatment for asymptomatic hemorrhoids is to eliminate or alleviate symptoms and to correct pathophysiological changes rather than eradicate the pathologically altered anal cushion. It is with the concept of painless and minimally invasive that the RPH procedure has been rapidly developed. RPH treatment principle: (1) mucosal wrinkling after ligation, the anal cushion is lifted; (2) local inflammatory reaction causes adhesion of mucosa, submucosa and superficial muscle layer, the anal cushion is fixed in a higher position; (3) partial blockage of blood supply to hemorrhoids or reduction of venous backflow, reducing congestion hypertrophy or blood flow stagnation of hemorrhoids, causing hemorrhoids to atrophy; (4) direct ligation of the upper edge of the base of hemorrhoids, which can stop bleeding immediately. RPH has the advantages of easy operation, no anesthesia, short operation time, mild postoperative pain and quick postoperative recovery. Its shorter hospital stay, lower complication rate, and milder postoperative pain make it more suitable as an outpatient surgical procedure, and at the same time, it also meets the requirements of minimally invasive surgery, which is worthy of clinical promotion.
