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
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 onto 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 |
