An Overview of Neurophysiologic Tests in Rectal Prolapse

  • Carlo Ratto


Diagnostic assessment in patients with rectal prolapse is a debatable field due to the very different clinical presentation of this condition and different preferences towards the variety of available diagnostic tests. Only full-thickness protrusion of the entire rectal wall through the anal canal should fall under the definition of “rectal prolapse”. However, internal rectal intussusception is very often included in this definition [1] because it is regarded as an early stage of overt rectal prolapse. In reality, rectal intussusception represents a wide variety of clinical and radiological conditions (schematically, rectoanal and rectorectal) with or without the association of other abnormalities (rectocele, sigmoidocele, enterocele, perineal descent, uterovaginal prolapse, cystocele), all of which contribute to obstructed defecation. Recently, the interpretation of intussusception has been challenged based on the high percentage of asymptomatic persons showing internal intussusception during defecography but which can disappear by the time of a follow-up defecography [2].
