Lorain-
Anywhere from 0 - 100%.
I think that you are looking for statistics.
Your surgeon can quote you these that are associated with the operation, as well as the postOp period. Your anesthesiologist (the gas passer) can discuss your risks associated with being put to sleep.
I believe that you chances for a good outcome here far exceed those chances of speaking to a human when you call a business these days.
And Lorain, not all colon surgery is equal. Whatever your condition is will have some bearing on how things are going to shake down.
