ABSTRACT
Rectal intussusception is a full-thickness invagination of the rectal wall occurring during evacuation and may result in symptoms of rectal evacuatory dysfunction (Figure 8.7.1). The presence of a rectocele, anterior bulging of the rectum into the posterior vaginal wall, is commonly associated with this finding and may also contribute to symptomatology Figure 8.7.2. Diagnosis of both these rectal wall morphological ‘abnormalities’ is traditionally made during evacuation proctography and, more recently, using magnetic resonance proctography.1 Evacuation proctogram demonstrating a circumferential full-thickness rectal intussusception.
