PPH is a new technique based on the theory of the anal cushion, using the anastomosis to treat cricoid prolapsed hemorrhoids. It is a kind of hemorrhoid anastomosis specially designed for the treatment of severe hemorrhoids of II-IV degree, which does not destroy the normal physiological function of the anal cushion and significantly shortens the operation time and greatly reduces postoperative pain. It is performed by circumferential excision of the rectal mucosa and submucosa and anastomosis of them at the same time in an instant, blocking the blood supply to the hemorrhoid and at the same time “bouncing” the prolapsed anal cushion back upward and restoring it to its normal position. It is suitable for patients with all types of hemorrhoids, especially heavy hemorrhoids of III-IV degree, anemic hemorrhoids of II degree, especially annular prolapsed internal hemorrhoids, and partial prolapsed rectal mucosa. For with very good curative effect. PPH has the following advantages: 1. Painless: pulling the prolapsed hemorrhoid 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. 2.Safety: No need to remove the anal cushion, which can preserve the normal function of the anus to the greatest extent and avoid complications such as anal stenosis and anal incontinence. 3.Little trauma and quick recovery: the anastomotic circumferential mucosa removal is a non-open wound with little bleeding, which eliminates the trouble of changing medicine after surgery and can resume normal life soon. 4.Short operation time: the whole process only takes about half an hour. 5.Wide range of surgical treatment: circumferential hemorrhoids, multivalve hemorrhoids, huge isolated hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, circumferential hemorrhoids, embedded hemorrhoids, rectal mucosal prolapse, prolapse, etc.
