Spontaneous transanal evisceration

Spontaneous rectal rupture with subsequent transanal evisceration is an unusual phenomenon that has been rarely reported in the literature. Owing to its infrequent occurrence, little is known about the aetiology of this event although a weakening of the anterior rectal wall has been proposed. This article describes the first reported case of spontaneous transanal evisceration occurring in a patient with chronic lymphocytic leukaemia.
