Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Rectal prolapse, also called rectal procidentia, occurs when anorectal tissue protrudes through the anus. Prolapse may be partial, involving only the mucosa, or complete, involving all layers of the rectal wall. Prolapse may result from laxity of the pelvic floor, weak anal sphincters, or lack of mesorectal fixation. Patients are often at extremes of age and may present with altered bowel habits, rectal mass, straining with bowel movements, and mucus discharge. Risk factors include multiparity, vaginal delivery, chronic constipation, and cystic fibrosis. Rectal prolapse is typically painless. Pain as a presenting symptom should prompt consideration of other diagnoses, such as rectal foreign body, neoplastic process, anorectal abscess, rectal polyp, or external hemorrhoids.
