When I was researching my surgery, I read that some surgeons prefer not to use the bougie, because of the risk of puncturing the esophagus. That risk is made more likely because the bougie is generally placed by the anesthesiologist, who may not have a lot of experience with it.
It made me worry a bit, but I had the surgery/bougie and all, and didn't have any problems as a result. The next issue is what size bougie to use. The surgeon wants the wrap loose enough to allow food through easily, but tight enough to keep acid down. It's a balancing act.
Hope everyone is well!
