Once anorectal stenosis is clearly diagnosed, active treatment should be adopted. For scarred anorectal stenosis due to repeated inflammatory irritation or after surgery, drug conservative or surgical treatment is used according to the classification. In short, as long as the patient has smooth defecation, no pain and no blood in stool, the treatment purpose is achieved. Conservative treatment: Generally speaking, for mild anorectal stenosis, conservative treatment has very good clinical effect. For example, a high-fiber diet and laxatives (such as lactulose, hemp nut lozenges or honey) are given to keep the stool open, thus reducing local irritation. If necessary, the patient can also spare open-cell or glycerin enemas to prevent the occurrence of fecal impaction caused by poor stool and fecal retention in the rectum for too long. Of course, for stenosis due to inflammatory diseases of the rectum, metronidazole solution or an appropriate amount of hormonal retention enema can be used to promote local symptom relief. In case of mild anal strictures, herbal or pepper salt water baths can also be used to promote blood circulation and scar absorption. If conditions allow, infrared irradiation and microwave therapy also have good effects on promoting scar absorption. Among the conservative treatments, for mild anorectal stenosis, anal dilation can be used to gradually “tear” the fibrotic tissue, thus reducing the pressure on the affected area and improving local blood circulation. Anal dilation can be done by finger dilation, anal mirror dilation of different diameters, daily or every other day at first, and then gradually until the stenosis dissipates and does not recur. Surgery: If conservative treatment is not effective, surgery should be used. 1.Anal stenosis: Whether it is linear or tubular stenosis, the scar tissue can be incised directly under anesthesia up to the superficial layer of the internal sphincter or the subcutaneous layer of the external sphincter, and then the anus can be slowly dilated until the anus is relaxed, or more than 3 incisions can be chosen to completely destroy the scar and reduce the chance of recurrence. 2, rectal stenosis: any stenosis that can be touched by fingers, regardless of the degree of stenosis, the stenosis ring can be slowly incised under direct anoscopy until the rectum does not feel like a ring, but the scar tissue should be incised in such a way that it does not penetrate the intestinal wall. To prevent bleeding from the broken end, the bleeding point should be lanced with absorbable sutures at all times, and the anus should be regularly dilated after surgery to prevent recurrence. At the end of both incisional procedures, if chymotrypsin (degrading scar) is injected into the incised scar site, it can promote scar absorption and softening. However, for stenosis due to tumor occupancy, either rectal or anal canal cancer should be treated with a treatment plan that is specific to the malignancy and no longer appropriate for the above treatments.
