RPH (automatic hemorrhoid ligation) is from the motherland of traditional Chinese medicine traditional ligation therapy development, this method is through the special automatic hemorrhoid ligature in the toothed line above the appropriate position of 1.5 ~ 75px will be a special ring of adhesive tape set in the hemorrhoidal base or hemorrhoids on the mucous membrane, through the tightening of the ring of adhesive tape, blocking the hemorrhoidal blood supply or to reduce venous flow backflow, to reduce hemorrhoidal congestion and hypertrophy or stagnation of the blood flow, so that the production of ischemia, atrophy, necrosis, and gradually fall off, wound tissue repair and healing. The hemorrhoids gradually fall off, and the wound tissue is repaired and healed. Therapeutic principle: 1, after ligation mucosal wrinkling, anal cushion uplift; 2, local inflammatory reaction caused by mucosa, submucosa and superficial muscle layer adhesion, anal cushion fixed in a higher position; 3, part of the yin cut off hemorrhoid blood supply or reduce venous reflux, reduce hemorrhoidal congestion and hypertrophy or stagnation of blood flow, so that hemorrhoidal block atrophy; 4, directly ligated hemorrhoidal block base, can instantly stop bleeding. Advantages: 1, ligation treatment of the whole process of automation, time-saving, energy-saving, practical, simple; 2, a single person can complete the operation, time-consuming only 5 to 10 minutes; 3, may not be anesthesia, the price is cheaper than the PPH; 4, the pain is mild, complications are rare; 5, no postoperative scar, does not destroy the normal structure and appearance of the rectum and the anal canal, the follow-up treatment for the convenience of a great deal. Disadvantages: can not be used for the treatment of simple external hemorrhoids, the external hemorrhoid part of mixed hemorrhoids, anal papilla hypertrophy, rectal polyps. Indications: 1, all stages of internal hemorrhoids (I ~ III stage has the best effect); mixed hemorrhoids internal hemorrhoid part; 2, for PPH or other therapies after hemorrhoid mass or anal cushion retraction is incomplete, RPH can be used as a complementary treatment; 3, other: rectal focal lesions, such as rectal polyps, rectal hemangioma or vascular malformation, and so on. Contraindications: 1, simple external hemorrhoids; 2, external hemorrhoids of mixed hemorrhoids; 3, anal papillae hypertrophy (special reminder: do not mistake anal papillae hypertrophy for polyps or internal hemorrhoids and ligation); 4, rectal polyps suspected of malignant transformation. Overall evaluation: 1, in all non-surgical treatments, the best efficacy of adhesive ring ligation; 2, adhesive ring ligation efficacy is second only to surgery; 3, adhesive ring ligation is the preferred treatment in Europe and the United States.
