Colon por enema

Look up "colon por enema" on youtube for a fluoroscopic view of a colon being filled with a barium enema. Several times you can see the radiologist's fingers massaging the colon as it fills. This is probably the best video of what happens in your colon as you take an enema. This is the video that shows a colon and lasts for 2:54.

I didn't get that when I tried.

Got one of a technician mixing a barium enema but nothing like what you describe

Can you post the exact link??
