Automatic hemorrhoid ligation (RPH) is from the motherland of traditional Chinese medicine traditional ligation therapy development, this method is through the special automatic hemorrhoid ligature in the tooth line above the appropriate position of 1.5 ~ 3cm will be specially designed adhesive ring sets in the hemorrhoids or hemorrhoids on the mucous membrane at the base of the hemorrhoids, through the tightening of the adhesive ring, strangulation blocking hemorrhoidal blood supply or to reduce venous reflux, to reduce the hemorrhoidal congestion and hypertrophy or stagnation of the blood flow, so that the ischemia, atrophy, Necrosis, ligature tissue gradually fall off, wound tissue repair and healing. It is one of the best non-surgical treatment methods at present. Therapeutic principle: First, after ligation mucosal wrinkling, anal cushion uplift; Second, the local inflammatory reaction caused by mucosa, submucosa and superficial muscle layer adhesion, anal cushion fixed in a higher position; Third, partially blocking hemorrhoidal blood supply or reduce venous backflow, reduce hemorrhoidal congestion and hypertrophy or stagnation of blood flow, so that hemorrhoidal block atrophy; Fourth, directly ligated hemorrhoidal block at the base of the hemorrhoidal block, can be instantly stop bleeding. Advantages: a, ligation treatment of the whole process of automation, time-saving, energy-saving, practical, simple; 2, a single person can complete the operation, consuming only 5 to 10 minutes; 3, without anesthesia, without hospitalization, inexpensive; 4, mild pain, 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 simple external hemorrhoids, mixed hemorrhoids of external hemorrhoids part, anal papilla hypertrophy, rectal polyps suspected of malignant changes in the treatment. Indications: First, all stages of internal hemorrhoids (I ~ III stage of the best results); mixed hemorrhoids internal hemorrhoids part; Second, PPH or other therapies for hemorrhoids or anal cushion retraction is incomplete, can be used as a complementary treatment of RPH; Third, the other: rectal focal lesions, such as rectal polyps, rectal hemangiomas or vascular malformations, and so on. Contraindications: i. Simple external hemorrhoids; ii. External hemorrhoidal portion of mixed hemorrhoids; iii. Enlarged anal papillae (special reminder: don’t mistake enlarged anal papillae for polyps or internal hemorrhoids and perform ligation); iv. Rectal polyps suspected of malignant transformation. Overall evaluation: I. In all non-surgical treatments, the efficacy of rubber band ligation is the best; II. The efficacy of rubber band ligation is second only to surgery; III. Rubber band ligation is the preferred treatment in Europe and the United States.
