[New methods of rectum and colon x-ray study in patients with constipation].

Rectal and colonic X-ray findings of 100 patients with constipation are presented. The study was performed by the authors' modified irrigoscopic procedure using barium enema. This made it possible not only to determine the shape, dimensions, and position of the rectum and colon, but to reveal a number of anatomic and functional changes in the rectum and pelvic floor (rectocele, rectal intussusception and prolapse, perineal descent, sigmoidocele), which was helpful in choosing a treatment policy for patients with colonic evacuatory dysfunction.
