Overview

Overview

Based on the radiological characteristics, rectal prolapse may be graded as internal rectal prolapse (recto-rectal intussusception and recto-anal intussusception) or external rectal prolapse (exteriorized rectal prolapse).

X Ray

X Ray

Standard defecography is a dynamic fluoroscopy study and a diagnostic method to visualize internal rectal prolapse radiologically, performed in the sitting position. After placing barium paste into the patient’s rectum, the patient is asked to squeeze to evacuate the barium.[1][2]

Oxford radiological rectal prolapse grading system:[1]
Grade Radiological characteristics
Internal rectal prolapse Recto_rectal intussusception I : High rectal Descends no lower than proximal limit of the rectocele
II : Low rectal Descends to the level of the rectocele, but not into sphincter/anal canal
Recto_anal intussusception III : High anal Descends onto sphincter/anal canal
IV : Low anal Descends into sphincter/anal canal
External rectal prolapse Exteriorized rectal prolapse V : Overt rectal prolapse Rectum protrudes from anus
