The life is better, the food is better, but the incidence of hemorrhoids has also increased. The pain of hemorrhoids is unbearable for the common man, and it is not a simple matter to get rid of the troubles caused by hemorrhoids. Among the surgical procedures, hemorrhoid surgery is not the most difficult, but it is something that most patients do not want to face. Perhaps none of the surgical procedures will leave the hearts of many hemorrhoid patients who have had surgery before, leaving those about to plop down on the operating table unsettled. The most advanced hemorrhoid surgery is PPH, also known as supra-hemorrhoidal circumferential hemorrhoidectomy, which is the circular removal of the prolapsed rectal mucosa above the hemorrhoid using a surgical instrument called a PPH anastomosis. PPH circumferential hemorrhoids are treated in a unique way. It uses a “lower disease up” treatment method in which the rectal mucosa is instantly excised and anastomosed by an anastomosis while preserving the anal cushion tissue. This blocks the blood flow to the hemorrhoid supply vessels and allows the prolapsed tissue to be suspended and fixed upwards. Since PPH operates in the rectal cavity above the dentate line, it is a painless zone surgery, which is painless for the patient and eliminates the root cause of hemorrhoids and avoids their recurrence. PPH circumcision is highly accurate, the operation takes only 15 minutes and the patient can defecate normally within 24 hours after the operation, and there is no pain after the operation, not to mention any complications such as anal stenosis or fecal incontinence, etc. PPH circumcision has good efficacy for some complicated hemorrhoids such as mixed hemorrhoids, annular hemorrhoids, severe hemorrhoid prolapse, prolapse, etc. PPH surgery is performed by circumferentially removing two centimeters of mucosa and submucosal tissue from the lower rectum, and then performing anastomosis of the mucosa and submucosal tissue to suspend the prolapsed anal cushion upward and allow it to return to its normal anatomical position. At the same time, the arterial branches supplying the hemorrhoids are cut off so that the blood flow to the hemorrhoids is reduced and the hemorrhoids gradually atrophy after surgery, eliminating the bleeding symptoms. Generally, III-IV degree hemorrhoids, anemia-causing II degree hemorrhoids, especially annular prolapsed internal hemorrhoids, are suitable for this procedure. The PPH procedure is characterized by 1. no pain; 2. simple operation, short operation time, small trauma of complications; 3. quick recovery, 2-5 days after surgery can be discharged; 4. few complications, fundamentally solving the above-mentioned complications of traditional surgery. 8 hours after PPH hemorrhoid supra-mucosal circumferential anastomosis can sit up, the first day after surgery can get out of bed. In contrast, Mr. Liu, who used the traditional procedure at the same time, still could not walk on the ground on the second day after surgery, and the wound healing was slow. Since we started to perform PPH surgery in 1999, we have performed such surgery on more than 1000 patients with good results.
