A. PPH technology is called “supra-hemorrhoidal mucosal circumcision”, which is a new technology based on the new understanding of the pathogenesis of hemorrhoids caused by anal cushion lesions. The PPH procedure uses a special instrument called the “PPH anastomosis” to make a circular excision of the prolapsed rectal mucosa above the hemorrhoid. 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, circular 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 truncating 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 hemorrhoid, multivalve hemorrhoid, huge isolated hemorrhoid, internal hemorrhoid, external hemorrhoid, mixed hemorrhoid, circumferential hemorrhoid, embedded hemorrhoid, rectal mucosal prolapse, prolapse, etc. 5.Suitable object: 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 from traditional treatment, and patients with mild prolapse and internal prolapse of rectal mucosa. What is the difference between PPH and traditional surgery? 1.The traditional surgery site is at the anal opening, while the PPH surgery site is at the lower rectum. 2.Traditional surgery removes the external hemorrhoids and ligates the internal hemorrhoids, with trauma to the anus, requiring a denudation process and daily drug changes, fumigation and medication changes after surgery. The wound hurts badly 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. The first day after surgery, you can defecate normally, and there is no need for special drug changes and fumigation. 3.Traditional surgery needs to cut off the sphincter to prevent anal stenosis, while PPH surgery does not damage the sphincter, so no anal stenosis or fecal incontinence will occur. The PPH surgery has the following features: (1) no pain after surgery; (2) short surgery time, little damage and fast recovery; (3) no damage to the anal sphincter, no incontinence and no anal stenosis; (4) recurrence rate of hemorrhoids; (5) no damage to the anal sphincter; (6) no damage to the anal sphincter; (7) no damage to the anal sphincter; (8) no damage to the anal sphincter; (9) no damage to the anal sphincter; (10) no damage to the anal sphincter; (11) no damage to the anal sphincter; (4) Low recurrence rate of hemorrhoids and beautiful appearance.
