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.
