'''Rectal prolapse''' is defined as the protrusion of the rectal mucosa from the anus. It can be classified as complete or incomplete.  A complete prolapse involves all layers of the rectal wall whereas an incomplete prolapse only involves the mucosal layer.

Protrusion of a red, elongated, swollen cylindrical mass from the [[Anus - Anatomy & Physiology|anus]] is seen.  It is vital to differentiate a rectal prolapse from an ileocolic [[Intussusception|intussusception]].  This can be done by passing a probe adjacent to the anus.  With a rectal prolapse, the probe cannot be successfully passed.

The everted tissue becomes [[Oedema - Pathology|oedematous]], which prevents it from being retracted back into the pelvic canal.  The exposed tissue is vulnerable, and depending on the duration of the prolapse, this can lead to inflammation, haemorrhage, [[Venous Congestion and Hyperaemia - Pathology|congestion]] and ulceration.

Prognosis is poor in untreated cases of chronic rectal prolapse. The prognosis for surgical patients is good provided the underlying cause is appropriately addressed.
