RPH hemorrhoid automatic ligation (RPH) is from the motherland of traditional Chinese medicine 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. The rubber ring sets in the hemorrhoids or hemorrhoids on the base of the mucosa, through the rubber ring tightening, strangulation blocking hemorrhoidal blood supply or reduce venous backflow, reduce hemorrhoidal congestion and hypertrophy or stagnation of the blood flow, so that ischemia, atrophy, necrosis, ligature tissues gradually fall off, the wound tissue repair and healing. It is one of the best non-surgical treatment methods at present. PPH surgery precautions: 1, case selection to II-IV internal hemorrhoids, external hemorrhoids part of the larger due to surgery can not solve the symptoms of external hemorrhoids, so it is not suitable for the operation. 2, strict preoperative bowel preparation and strict aseptic operation is the key to prevent infection. 3.The retraction of the non-invasive forceps should be gentle, and the tearing of the anal verge is the main cause of postoperative pain. 4, The purse-string suture should be accurate in depth, uniform across and make the purse-string suture in a cross-section. According to the size of hemorrhoids, the degree of prolapse to control the need to remove the width of the tissue and the height of the anastomosis. If necessary, the double purse, two purse should pay attention to keep parallel, not too wide spacing. 5, can be in the hemorrhoid nucleus larger point for the beginning and end of the purse sewn, the beginning and end of the point tends to cut more tissue, so that suspension and blocking the effect of blood supply will be better. 6.After striking the anastomosis, the anastomosis should be tightly closed for a slightly longer period of time to ensure a tight anastomosis and to reduce the anastomotic blood seepage. 7.Check the anastomosis carefully, if there is a pulsatile bleeding point, it should be made under direct vision as “8” suture, until the bleeding stops. 8, anastomosis coated with astringent hemostatic Chinese patent medicine selenium to prevent anastomotic bleeding is helpful. 9.Postoperative placement of the ventilator 24h can be observed whether there is bleeding and the amount of bleeding and can reduce intestinal flatulence. 10, to ensure that the intake of adequate water intake of adequate water can achieve the purpose of softening the stool, have a better effect of preventing constipation. Ensure 1000ml of water intake every day. Drinking cold boiled water every morning can stimulate the gastro-colonic reflex and achieve the purpose of promoting defecation, but need to pay attention to the appropriate adjustment of water temperature according to the season. 11, take a sufficient amount of food fiber The diet should contain a sufficient amount of cellulose to maintain normal adult defecation of food fiber intake of 20g per day. cellulose has a hydrophilic, can absorb water, so that the food residue expansion is easy to promote; residue can stimulate intestinal peristalsis, conducive to stimulate the intention to defecate and defecation reflex. In addition, the intake of bananas food fiber drink fruits and vegetables or bamboo shoots cereal bran and other multi-fiber foods have the effect of promoting defecation.
