Keep up the good work and attitude. My wife went through the same thing several years ago and still has good days and bad days. The bad days usually come from trying to do too much or eating the wrong things (which she loves).
The surgeon told us that most folks in that situation: 15% are back within a year for removal/another resection, 15% never have anothere problem, and the other 70% are somewhere in between. At this point for us her "Gastro is saying, 'You need to go to Vandy', you are past my expertice!"
Best of luck and remember our prayers are with you
