Rectal prolapse is generally divided into internal rectal mucosal prolapse and external prolapse, also known as rectal procidentia. If it is an internal prolapse, an anoscopy combined with defecography is required to examine the degree of laxity of the local rectal mucosa. If it is an external prolapse or rectal procidentia, the patient generally presents with a prolapsed swelling when squatting, and this can be further evaluated with a digital rectal examination to assess the local tightness of the anus. If rectal prolapse occurs, surgical treatment is recommended as it tends to be quite effective. In cases of pediatric prolapse or mild prolapse, traditional Chinese medicine enemas may be used to alleviate local symptoms.
