In the clinic, we often see patients with “prolapse” as the main complaint. The patient’s intention is to have a prolapsed mass in the anus during defecation, after defecation, increased abdominal pressure (e.g. coughing, breath-holding, etc.), walking or standing. In fact, this is a generic term for all diseases in which a mass is prolapsed from the anus. There are various diseases with “prolapse”, which are described as follows: Rectal prolapse: whether it is rectal mucosal prolapse or rectal prolapse, it can be prolapsed during defecation, and can be retracted after contraction, some of which need to be retracted by hand, often staining underwear due to mucus outflow, accompanied by perianal itching. When the mucous membrane is damaged, ulceration and bleeding may occur. If the patient squats and strains, the mucosal prolapse is only two layers of folded mucosa. In complete prolapse, the entire intestinal wall is turned out, the mucosa is folded in concentric rings, and the swelling has layers of folding, like an inverted pagoda.
