The difference between PPH surgery and traditional surgery A. Traditional surgery site in the anal opening, and PPH surgical therapy site in the lower rectum, traditional surgery will be external hemorrhoidectomy, internal hemorrhoid ligation, the anus has a trauma, the need for the process of decolonization, postoperative daily dressing changes, fumigation, and medication changes. The wound is in severe pain during defecation and can only heal gradually. PPH surgery site in the lower part of the rectum, resection at the same time with the anastomosis, the whole process takes only a few minutes, retaining the anal cushion tissues, the anus is not traumatized, there is no denucleation process. You can have normal bowel movement on the first day after surgery, and there is no need for special dressing change or fumigation. Traditional surgery needs to cut the sphincter muscle to prevent anal stenosis, while PPH surgery does not damage the sphincter muscle, so there will be no anal stenosis or fecal incontinence. Traditional surgery is symptomatic treatment, PPH surgical method is to treat the cause of the disease. PPH surgery due to the preservation of the anal cushion, does not damage the anal sphincter, no surgical incision in the anus, maximize the preservation of the physiological function of the anal cushion, so it has: 1, no pain after the operation 2, short operation time, small damage, fast recovery, 3, no damage to the anal sphincter, no fecal incontinence, anal stenosis, 4, hemorrhoids recurrence rate is low, the appearance of the aesthetics 3, PPH why have the advantage 1, due to the non-excision of the anal cushion, fine after surgery, so there will be no anal stenosis. Because of not removing the anal cushion, fine defecation function is not affected after the operation; 2, because the wound is above the dentate line, no spinal nerve sensory endings, postoperative pain is significantly reduced; 3, because the wound is an anastomosis, no open, the healing time is extremely shortened; 4, because of the anastomosis is relatively fixed in size and is located in the mucosa of the rectum, theoretically will not occur due to the anus stenosis caused by the contracture of the skin scars; 5, due to the supporting instruments, the operation is simple and standardized. The operation is simple and standardized, which is easy to promote and evaluate the prognosis.
