Different types of hemorrhoids are treated in different ways. They include medication, injections, ligation, cryotherapy, microwave therapy, radiofrequency therapy, and surgery. Generally speaking, asymptomatic people do not need treatment. 1 to 2 degrees of hemorrhoids can mostly be treated with general treatment. These include avoiding irritating foods, drinking more water, eating more dietary fiber, keeping stools open, preventing diarrhea, taking warm baths, keeping the perineum clean, doing frequent anal stretching exercises, and using local suppositories and ointments to protect the mucosa. Of course, microwave therapy, radiofrequency therapy and collar ligation therapy can also be applied to 1-2 degree internal hemorrhoids as appropriate, but care should be taken to prevent complications. In contrast, for 3rd to 4th degree internal hemorrhoids, mixed hemorrhoids and thrombosed external hemorrhoids, surgical treatment is required in most cases. The mode of surgery should also be chosen according to the patient’s condition and the experience of the surgeon. In addition to the various treatments mentioned above, a new technique for treating hemorrhoids – PPH surgery – has emerged in recent years. Based on the new concept of the cause of hemorrhoids – the theory of inferior displacement of the anal cushion, Longo in Italy was the first to use the anastomotic suprahemorrhoidal mucosal circumcision in 1998, also known as PPH surgery, which is an acronym for “Procedure for Prolapse and Hemorrhoids “The principle of PPH surgery is to remove the rectal mucosa above the hemorrhoid area in a circular fashion and use an anastomosis to anastomose the rectal mucosa to suspend the slippery anal cushion upward and return it to its normal anatomical position. At the same time, the blood flow is reduced by cutting off the branches of the arteries, causing the hemorrhoid nucleus to gradually shrink. PPH surgery has obvious advantages compared with traditional surgery. Firstly, PPH surgery does not remove the anal cushion, which preserves the function of the anus to the greatest extent and avoids complications such as anal stenosis and anal incontinence, etc. Secondly, the surgery removes the rectal mucosa located on the dentate line, which does not damage the perianal skin, thus there is no pain after the surgery; at the same time, the anastomosis is a non-open wound after the circumferential removal of the mucosa, which eliminates the trouble of changing medicine after the surgery, and the patient has a short hospital stay and can resume normal life soon. The patient can return to normal life soon. For some complex hemorrhoids, such as mixed hemorrhoids, ring hemorrhoids, severe hemorrhoid prolapse, prolapse, etc., PPH shows its unique treatment advantages. It is especially an epoch-making revolution in the treatment of severe hemorrhoids. The indications for PPH surgery are: III and IV degree internal hemorrhoids with circumferential prolapse; II degree internal hemorrhoids with recurrent bleeding; anterior rectal bulge and endorectal prolapse leading to obstruction type constipation at the functional outlet. PPH surgery alone is not suitable for mixed hemorrhoids, mainly external hemorrhoids, connective tissue external hemorrhoids and embedded hemorrhoids.
