Crohns misdiagnosis

I was diagnosed with Crohns in 2002 after going to the ER with abdominal pain and vomiting. By the next morning I was scheduled for exploratory surgery which resulted in a resection of the ileum and part of colon. Since surgery I have had no pain and no other symptoms other than chronic diarrhea which I think is a result of the removal of the ileum. Has anyone else gone this long without symptoms. Also I stopped all medication six months after surgery in 2002. I am wondering if I was misdiagnosed.
