The newer concept of hemorrhoid disease is the pathological enlargement and displacement of the anal cushion, which produces bleeding, prolapse and painful symptoms. The more common treatment methods such as external peeling and internal ligation, drug injection of withered hemorrhoids can get rid of the painful symptoms of hemorrhoid disease, but some patients relapse after 2-3 years or after women give birth. From the pathology of the occurrence of hemorrhoids, the bleeding and prolapse of the hemorrhoid nucleus (anal cushion) is associated with changes in the mucosa and submucosa tissue on the hemorrhoid. In clinical observation, the enlarged and or displaced hemorrhoid nuclei of erosion and bleeding have mucosal relaxation and submucosal vascular dilatation in the suprahemorrhoidal area, and finger diagnosis and ultrasound examination prove the obvious abundance of arteriovenous vessels on the pathological anal cushion hemorrhoids. Since 2005, our anorectal department has adopted “three-level zoning treatment” for internal hemorrhoids and mixed hemorrhoids, i.e. upper hemorrhoid level, internal hemorrhoid level, external hemorrhoid level, and three key areas: right anterior, right posterior, and left middle, which are treated separately. The first step is to perform mucosal sutures on the right front, right back and left middle hemorrhoids, which we believe is the key step in the treatment of hemorrhoids: generally, 3 consecutive stitches of No. 7 silk thread are used to tie the knot at 0.5-1.0 cm stitch spacing above and below, and after the sutures are applied to the pathologically enlarged and displaced hemorrhoids (anal cushion), the hemorrhoid nucleus is obviously reduced, moved up and fixed. For areas where the hemorrhoid nucleus is not obvious also suture, there is a preventive effect to prevent the development of the hemorrhoid nucleus. The operation is safe, simple and easy to perform, the purpose of which is: to shorten and fix the mucous membrane and submucous layer on the hemorrhoid on the muscular wall by lifting up; to block the blood supply to the hemorrhoid and make it atrophy. This step will solve the problem for hemorrhoids that are not significantly enlarged and displaced, while the second step of ligation and excision is required for hemorrhoids that are significantly enlarged and displaced. For external hemorrhoids that have an obvious uneven anal appearance, the third step is to remove the connective tissue dermatome and blood sinus with a cosmetic approach. In addition, for patients with combined anal fissures and or anal canal tension, partial release of the internal sphincter and external sphincter subcutaneous ring is performed to the satisfaction of the anal canal finger. At present, the procedures that can make the suprahemorrhoidal mucosa lift and shorten and fix and block the blood flow are PPH, TST and PRT, compared to TST which has the advantage of clearly selecting the suprahemorrhoidal mucosa in the lesion area and is more targeted.
