title: Evacuation proctography combined with positive contrast peritoneography to demonstrate pelvic floor hernias.
abstract: BACKGROUND
  To demonstrate the pelvic peritoneal recesses during voiding, evacuation proctography was combined with positive contrast peritoneography.
  
  
  METHODS
  In 30 constipated patients, peritoneography was performed, followed by proctography.
  
  
  RESULTS
  During evacuation rectogenital herniation developed in 20 patients (66%), without visceral filling in 12 (40%).
  
  
  CONCLUSIONS
  Posterior pelvic floor hernia is common during defecation. Less than half fill with bowel and many may not be apparent on standard proctography.
