Abstract:
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.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
