PPH domestic stapler hemorrhoid surgery

PPH is an anastomotic hemorrhoidectomy, which is suitable for all types of hemorrhoids, especially patients with severe internal hemorrhoids and partial rectal mucosal prolapse. The principle is: while retaining the anal pad, circularly remove and anastomize some internal hemorrhoids and the upper mucosa and submucosa of the hemorrhoids, and perform anastomosis. It not only blocks the blood supply of hemorrhoids, but also suspends and fixes the slippery tissue, and restores the pathological state of the anal canal to the normal anatomical state. Also called "superior hemorrhoidal mucosal circumcision", this is a new technology based on a new understanding of the pathogenesis of hemorrhoids caused by anal pad lesions. PPH surgery uses a special device called a "PPH stapler" to perform a circular resection of the rectal mucosa prolapse band above the hemorrhoid. During the operation, expand the anus first, and sew the rectal mucosa in a circle about 4 cm above the dentate line (the boundary line between the rectum and the anal canal), and then insert the PPH stapler into the anus. The stapler can prolapse the mucosal band. The whole process takes about half an hour. Because the rectal mucosa above the dentate line is innervated by the visceral nerves, the patient has almost no pain after the operation; and because the rectum mucosa prolapse is removed, the terminal anastomotic branch of the arteriovenous end of the rectum is blocked, which eliminates The origin of hemorrhoids has very good therapeutic effects on internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, ring hemorrhoids, severe hemorrhoid prolapse, and prolapse of the anus. It has the characteristics of quick effect, fast recovery and no pain after operation.
