Rectal prolapse primarily refers to excessive laxity of the rectal mucosa within the anal canal. This lax mucosa accumulates at the anal opening, forming a clinical symptom. Patients may experience significant local swelling and a feeling of falling down. In severe cases or when the prolapse overly obstructs the anal opening, it might lead to difficulties in defecation and constipation. To diagnose rectal prolapse, an initial assessment typically involves a digital rectal examination and an anoscopy to simply and initially screen for the presence of mucosal prolapse. Further, a defecography might be required to ascertain the severity of the rectal prolapse. For mild rectal prolapse, topical medications can be used to alleviate symptoms. In cases of moderate or severe rectal prolapse, surgery is necessary to excise the lax mucosal loop.
