Prolapse usually requires surgery. Prolapse, also known clinically as rectal prolapse, is a condition in which the patient’s rectum, rectal mucosa, anal canal, and even sigmoid colon are displaced downward and prolapse out of the anus. Causes of prolapse include congenital abnormal development of the anal sphincter, surgery, injury to the anal sphincter, and rectal support tissue, as well as unformed sacral curvature in children, and chronic diseases that cause increased abdominal pressure in old age or long term. Prolapse can be divided into three degrees according to the distance of prolapse. For first degree prolapse, the symptoms can be relieved by non-surgical treatment, while for second and third degree prolapse, surgical treatment is required to control the symptoms.
