How big are the risks of slippage? flipping? leaks?

There are too many factors to be able to predict the outcome.

One side of the coin: it depends on the surgeon's skill, how well post-op instructions are followed, what technique they used, which band was placed.

Then the flip side: complications can occur even if the surgeon is perfect and instructions are followed to the letter....so bottom line, it isn't predictable.

My surgeon told me that across the board, the likelihood of some kind of complication with a lapband is 20%. Yes, that is pretty high, but he is talking about over the life of the band people who have some type of minor or major complication. I think serious complications are much more rare. Has anyone else heard other stats?
