That's odd...every GI doc I have ever spoken to has said the opposite. I had 18" TI removed, now I have rectal issues that I never had before. I think that qualifies me as abnormal per your conference too...I think mine has spread, but fortunately, not a long distance.
Unless, they would say I had these issues all along they just never showed on previous tests...
CD....always leaves you with more questions than answers!
