The barium swallow test I had after surgery wasn't done with a lot of barium. I only had to take a couple small drinks. More like sips. The first time they used the regular shake up stuff, but the redo I had the thinner stuff. Both times they did it with me standing. Some surgeons do it to be sure there is nothing leaking before they let you eat and drink.
Believe me you don't want a leak.....had a leak 4 days after my redo and just recently had a tear in my esophagus that leaked into my chest. Both of those were the worst pain I have ever had. The leak after my redo wasn't the wrap area, but was from them taking the one done incorrectly apart.
