Rectal prolapse

Rectal prolapse is a pathological condition where the lower end of the anal canal, rectum and even the sigmoid colon is displaced downward and protrudes outside the anus. Only submucosal prolapse is incomplete prolapse, and full rectal prolapse is complete prolapse. The prolapsed part is called internal prolapse when it is located in the rectum, and it is called external prolapse when it is out of the anus. Rectal prolapse is more common in children and the elderly. Rectal prolapse is a self-limiting disease in children, most of which heal before 5 years of age, so non-surgical treatment is the main treatment. In adults with complete rectal prolapse, long-term prolapse will cause anal incontinence, ulcers, infection around the anus, rectal hemorrhage, prolapsed intestinal edema, necrosis, and stenosis due to long-term prolapse, which should be mainly treated by surgery.
