Prolapse, also called prolapse of the anal canal and rectum, is a disease in which the anal canal, rectum, rectal mucosa, and part of the sigmoid colon are displaced downward and prolapse out of the anus, mostly in the elderly and children. In infants and children, prolapse is mainly treated by non-surgical treatment, while in adults, sclerotherapy and surgery are mostly used. 1. General treatment: infants and children with prolapse of the anal canal and rectum have the possibility of self-healing, and can be treated non-surgically, even if the prolapsed part is reset immediately afterwards, in a prone or lateral position, with adhesive tape to fix both buttocks after reset. After adult prolapse, the exercise of lifting the anus can be done. For those who have poor reset effect, it is recommended that constipation, cough and other diseases causing increased abdominal pressure should be actively treated to avoid aggravating the degree of prolapse and recurrence after surgical treatment; 2. Injection therapy: the treatment will inject sclerosing agent into the submucosa of the patient’s prolapse site, so that the mucosa and muscle layer will produce sterile inflammation and adhesion fixation. It is mainly applied to rectal prolapse within the mucosa. Commonly used sclerosing agents include polyglactin, phenol vegetable oil, aqueous quinine hydrochloride urea solution and some herbal preparations. The recent effect after injection treatment is relatively good; 3, surgical treatment: prolapse surgical treatment is applicable to patients with symptoms such as rectal mucosal congestion and edema, anal incontinence, rupture and bleeding, etc. Common surgical methods include transabdominal rectal anterior suspension, transabdominal rectal posterior suspension fixation, rectal anterior wall folding, rectal resection fixation, anal tightening, etc. Suitable surgical procedures can be selected according to the degree of prolapse and general condition of patients The appropriate surgical procedure can be chosen according to the degree of prolapse and general condition of the patient.
