The slow healing of postoperative trauma after anorectal surgery prolongs the patient’s hospital stay, increases the cost of treatment, and also increases the patient’s mental stress and affects the patient’s quality of life for a certain period of time, for the following reasons: 1. Infection: Most anorectal surgeries are contaminated surgeries, and the inevitable postoperative defecation has been threatening the trauma, which inevitably increases the incidence of infection. Due to the increase of exudate from the trauma surface in case of infection, it increases the local tension and hinders the healing of the trauma surface. 2.Age: As age increases, human tissue proliferates and regenerative capacity decreases, which obviously affects the healing rate of the trauma. 3, combined with diabetes: because the patient’s glucose metabolism is disturbed, the body’s immunity is low and more susceptible to infection, due to reduced protein synthesis and accelerated catabolism, resulting in a negative nitrogen balance, so that the patient’s tissue repair ability decreases, delaying wound healing. 4, nutritional deficiency: especially when protein deficiency, poor granulation tissue and collagen formation, directly affecting the wound healing. 5. Combined tuberculosis: Due to the combination of Mycobacterium tuberculosis infection, antibiotics are used but the purpose of anti-infection is not achieved, which leads to delayed wound healing. 6. Combination of Toxoplasma gondii: The presence of TP leads to inflammatory cell infiltration, tissue swelling, hyperkeratosis of the epidermis, and even the formation of focal erosions, making the trauma difficult to heal. 7. Psychological and psychiatric factors: Psychological and psychiatric factors can stress the hypothalamic-pituitary-adrenal medullary axis to cause abnormalities in the mediation of the immune system, reducing the immune inflammatory response and affecting the ability to clear wound germs, thus also indirectly affecting wound healing.
