The PPH technique is called “suprahemorrhoidal mucosal circumferential hemorrhoidectomy”, which is a new technique based on the new understanding of the pathogenesis of hemorrhoids caused by anal cushion lesions. The PPH procedure is a circular excision of the prolapsed rectal mucosa above the hemorrhoid using a special instrument called the PPH anastomosis. The surgery is performed by widening the anus and suturing the rectal mucosa in a loop about 4 cm above the dentate line (the junction line between the rectum and the anal canal), then inserting the PPH anastomosis into the anus, the anastomosis can remove the prolapsed mucosal band, and the whole process only takes about half an hour. The surgery not only removes the prolapsed rectal mucosal band, but also blocks the terminal anastomotic branch of the end of the rectum, eliminating the root cause of hemorrhoids, which has a very ideal treatment effect on internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, ring hemorrhoids, severe hemorrhoid prolapse, prolapse, etc. It has the characteristics of quick effect, quick recovery and no pain after surgery. Technical advantages 1.Safety：No need to remove the anal cushion, which can retain the normal function of the anus to the greatest extent and avoid complications such as anal stenosis and anal incontinence. 2.Painless: Pulling the hemorrhoid out of the anus back to its original position, while cutting off the blood vessels that provide blood to the hemorrhoid, without damaging the perianal skin, so there is almost no pain after the operation. 3.Little trauma and quick recovery: The anastomosis circumferential resection of mucosa is a non-open wound with little bleeding, which eliminates the trouble of changing medicine after surgery and allows you to resume normal life soon. 4.Clinical hemorrhoids, multivalve hemorrhoids, giant isolated hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, circumferential hemorrhoids, embedded hemorrhoids, rectal mucosal prolapse, prolapse, etc. 5.Suitable objects: Because of less damage, it is especially suitable for middle-aged and elderly people, white-collar people who pay attention to efficiency and those who relapse with traditional treatment and patients with mild prolapse and rectal mucosal prolapse. What is the difference between PPH and traditional surgery? 1. (1) The traditional surgery site is at the anal opening, while the PPH surgery therapy site is at the lower rectum. (2) Traditional surgery removes external hemorrhoids and ligates internal hemorrhoids, with trauma to the anus, requiring a denudation process and daily medication changes, fumigation, and drug changes after surgery. The wound hurts severely during defecation and can only heal gradually. In contrast, the PPH surgery site is in the lower rectum, and the anastomosis is performed at the same time, and the whole procedure takes only a few minutes, preserving the anal cushion tissue, with no trauma in the anus and no denucleation process. Normal defecation is possible on the first day after the operation, and there is no need for special drug changes and fumigation. (3) The sphincter muscle needs to be cut off to prevent anal stenosis in traditional surgery, while PPH surgery does not damage the sphincter muscle, so no anal stenosis or fecal incontinence will occur. (4) Traditional surgery is symptomatic treatment, while PPH surgery is to treat the cause of the disease. 2, PPH surgery because of the preservation of the anal cushion, no damage to the anal sphincter, no surgical incision in the anus, the maximum retention of the physiological function of the anal cushion, so it has: (1) no pain after surgery (2) short surgery time, little damage, fast recovery, (3) no damage to the anal sphincter, no incontinence, anal stenosis (4) low recurrence rate of hemorrhoids, beautiful appearance
