contrast enema
Fluoroscopic examination using contrast material introduced through the rectum to evaluate colonic anatomy and motility in pediatric patients.
Full Definition
A diagnostic imaging procedure where contrast material (barium or water-soluble contrast) is administered via the rectum under fluoroscopic guidance to evaluate the colon and sometimes the terminal ileum. In pediatric radiology, contrast enemas are performed to diagnose conditions such as Hirschsprung disease, intussusception, or colonic atresia. The procedure requires careful attention to contrast pressure, volume, and patient comfort. Water-soluble contrast is preferred when perforation is suspected or for therapeutic reduction of intussusception. Age-appropriate preparation and sedation considerations are essential for successful examination completion.
Usage
Usage note: Specify contrast type when relevant; distinguish therapeutic from diagnostic procedures.
