PPH is a new technique based on the new understanding of the pathogenesis of hemorrhoids caused by anal cushion lesions, and it involves the circular removal of the prolapsed rectal mucosa above the hemorrhoid using a special instrument called the PPH anastomosis. It is ideal for internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, circumferential hemorrhoids, severe hemorrhoid prolapse, prolapse, etc. It is used for the treatment of III and IV degree internal hemorrhoids. The principle of PPH surgery is to insert a special circular anastomosis into the rectum through the anus and circumferentially remove the mucosa and submucosa of the lower rectal wall, and perform anastomosis at the same time to lift the prolapsed anal cushion and restore the normal anatomical position of the anal cushion, which plays the role of “suspension”, while cutting off the arterial blood branches supplying the hemorrhoids, which plays the role of “disconnection”. “The first step of PPH surgery is to cut off the arterial blood supply to the hemorrhoid nucleus, thus achieving the goal of radical treatment. The first step of the PPH procedure is to insert the PPH anastomosis into the pain-free zone about 4 cm above the junction line between the rectum and the anal canal for treatment. In the second step, the PPH anastomosis is done instantly by removing about 3 to 100 px of tissue circumferentially over part of the internal hemorrhoid and the mucosa and submucosa above the hemorrhoid, while the anastomosis is completed instantly, blocking the bleeding of the hemorrhoid supply vessels and at the same time suspending the slipped tissue upward to fix it. In the third step, the vascular supply of hemorrhoids is cut off and the internal and external hemorrhoids automatically shrink, thus eliminating the root cause of hemorrhoids and avoiding the recurrence of hemorrhoids to achieve the treatment purpose. 1.Safety: No need to remove the anal cushion, retaining the normal function of the anus to a greater extent and avoiding complications such as anal stenosis and anal incontinence. 2.Minimal pain: 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 the pain is almost minimal after the operation. 3.Small trauma, fast recovery: anastomotic circumferential excision of the mucosa is a non-open wound, bleeding less, eliminating the trouble of changing y after surgery, can quickly return to normal life. 4.Clinical hemorrhoids, multi-flap hemorrhoids, huge 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 from traditional treatment, and patients with mild prolapse and internal prolapse of rectal mucosa. Postoperative care of PPH (1) Diet: fluid or semi-liquid diet on the 1st day after surgery, and ordinary diet on the next day; (2) Defecation: controlled defecation for 1 day after surgery, and oral liquid paraffin oil or hemp pills to soften the stool, and sitz bath after the stool. No need to change medication, no need to incorporate suppositories in the anus, etc.; (3) the use of antibiotics: general postoperative prophylactic application of antibiotics 1 to 3 d to prevent anastomotic infection; (4) observation and treatment of complications: if the operation is standardized, there are generally no recent complications, and conversely, bleeding, anal pain and distant anastomotic stenosis. Therefore, blood pressure and pulse should be closely monitored within 24h after surgery, and the stenosis should be dilated if necessary, and the stenosis should be severely incised by hanging wires. PPH, the “gold standard” of anorectal disease treatment Three precise detection ——- of lesion volume, morphology precision diagnosis advantages, unique and advanced ——- eliminate lesions so as to completely cure safe and reliable ——- effective cure rate of high experts, applicable to internal hemorrhoids, mixed hemorrhoids, prolapse and other disease comments, under the disease on the treatment , minimally invasive and painless, no complications rapid recovery, effective treatment, low recurrence rate.
