Anal sputum disease, "Surgery Zhengzong" has said that "the husband is dirty with poison, the wine has a strong taste, the hard work, the poisonous and the anus forms a lump", which explains the etiology and pathogenesis of the perianal abscess. Chinese medicine believes that the anus the formation of sputum is caused by perianal abscess that does not heal for a long time. The anus is dominated by the bladder meridian of the full sun. The body's damp and heat residual toxin is injected into the bladder, which eventually causes heat to overcome meat rot. "Lectures on Evil Flesh Forty-two" pointed out: "Evil flesh is also carrion. After carbuncle ulceration, the carrion must be removed first, which means that the old and the new." The existence of the carrion affects the normality of the fresh granulation tissue of the wound. The growth and decaying granulation tissue affects the healing of the wound: Ren Donglin believes that [2], followed by the sequelae of the abscess rupture or incision drainage that occurred around the anorectum, is that the anal canal or rectum communicates with the perianal skin A kind of granulation canal, which often has the risk of sepsis and sepsis, and the conservative treatment effect is not good. AGGARWAL V[3] believes that due to the special anal anatomy position, postoperative open trauma, local pollution and Long-term repair is inevitable, so that some patients have slow wound healing and poor healing quality after anal fistula surgery. Synthesis slows down and decomposition speeds up, affecting wound healing. "After anal fistula, the tissue will release inflammatory factors due to trauma stimulation, causing local swelling, compressing blood vessels, and causing local blood to run poorly", which will cause local tissue ischemia and hypoxia , Blood viscosity increases, resulting in insufficient tissue perfusion. Studies such as Jonsson [34] found that insufficient tissue perfusion will cause a decrease in the oxygen content and collagen content of the wound, and the perfusion of wound tissue can promote wound healing. Therefore, the long time for wound healing after anal fistula, postoperative infection, postoperative pain and other aspects trouble patients and anorectal clinicians. External treatment of traditional Chinese medicine has a long history of promoting wound healing after anal fistula. There are many treatment methods, and the curative effect is remarkable, which reflects the unique advantages of the external treatment of TCM. The author consulted the relevant literatures in recent years about the external treatment of TCM to promote the healing of wounds after anal fistula. Conduct an overview.
