[Use of modified irrigoradioscopy in the diagnosis of external and internal rectal prolapse]

The paper gives colonic X-ray findings in 39 patients with rectal prolapse. Of them, 20 and 19 patients were found to have internal and external rectal prolapse, respectively. Studies were conducted by the modified irrigoscopy developed by the State Coloproctology Research Center, Ministry of Health of the Russian Federation, to explore the anatomic and functional status of the rectum and the fundus of the pelvis in patients with impaired defecation. The X-ray sign of circular invagination that had been detected by the authors allowed them to make the diagnosis of internal rectal prolapse with the greatest assurance. The modified irrigoscopy in combination with oral enterography for external rectal prolapse could show associated changes, including enterocele and sigmocele.
