Other names for a return flow enema include Barium enema and Retrograde enema.
Step-by-step explanation:
One other name for a return flow enema is a Barium enema. This procedure involves the insertion of a liquid contrast material called barium into the rectum to help visualize the colon and rectum on an X-ray. It is often used to diagnose conditions such as bowel obstructions, polyps, or tumors.
Another name for a return flow enema is Retrograde enema. This technique is used to treat constipation or to cleanse the colon before certain medical procedures. It involves inserting a tube into the rectum and infusing a fluid such as saline or a laxative solution into the colon, then allowing it to flow back out.
