What is granulation Granulation is the fresh meat of the wound repair process. What we call “granulation” actually refers to “granulation tissue”. Granulation tissue refers to the process of tissue injury, in order to replace the necrotic tissue and the formation of new capillary-rich infantile stage of the fibrous connective tissue. Granulation tissue is an essential tissue in any wound repair process. Observed with the naked eye, the surface of the granulation tissue is fine granular, bright red, soft and moist, easy to bleed without pain, similar to the shape of tender meat, so it is named “granulation”. Characteristics of granulation Bleeding easily but painless. The granulation tissue often contains a certain amount of edema fluid, so it looks tender, and sometimes it will be elevated with the plane of the wound. The granulation tissue contains abundant capillaries, and the wall is thin, so there may be a small amount of blood oozing when the dressing is changed and gently touched. But the granulation tissue does not contain nerve fibers, so even if touched, the pain is not obvious. Third, the role of granulation granulation tissue in the process of tissue damage repair has an important role 1, anti-infection to protect the wound; 2, to fill the wound and other tissue defects; 3, mechanization or parcel necrosis, thrombus, inflammatory exudate and other foreign bodies. So the growth of granulation tissue is a normal process in the postoperative recovery of anal and intestinal surgery. Fourth, the end of the granulation Formation of scar Granulation tissue can begin to appear within 2 to 3 days after tissue injury, fill the wound or mechanized foreign body. Over time, the granulation tissue matures in the order of its growth. As it matures, there is a gradual decrease in water absorption, a decrease and gradual disappearance of inflammatory cells, and a decrease in the occlusion and number of capillaries. Eventually the granulation tissue matures into fibrous connective tissue and transforms into scar tissue. Fifth, abnormal granulation overgrowth Sometimes, the granulation will also be edema and overgrowth. It looks like it is protruding from the incision, is very prone to bleeding, and is extra fragile. This is often seen in some post-surgical wounds of anorectal disease. This is an abnormal granulation, which is called “pterygium” in Chinese medicine, and it is easy to cause non-healing or slow healing of the wound, and some of them have formed a false healing. The main reasons are: 1, the wound is too large, such as large abscess and anal fistula after surgery wound; 2, the wound tension is too large, such as anal fissure and ring mixed hemorrhoid after surgery wound; 3, the weak; 4, blind use of drugs to promote the healing of wounds; 5, the local airtight, damp, and excessive use of oily drugs. Sixth, the treatment of abnormal granulation pruning is not the only way in order to promote faster and better wound healing, the abnormal granulation needs to be dealt with. 1, larger wounds should be compressed oil gauze when changing the dressing. 2.Clean, depending on the amount of secretion, change the auxiliary material in time, and try to keep the localization relatively dry. 3.Use 20% concentrated sodium chloride to wet compress the wound. 4, concentrated saline or alum water sitz bath. 5, protruding or turned out of the wound buds need to be trimmed in time. First, what is the meat buds meat buds is the wound repair process of fresh meat. Our mouth “bud”, in fact, refers to the “granulation tissue”.
