There are different kinds of enteric coating. Most enteric coated tablets that aren't 5ASAs are meant to dissolve in the stomach or small intestine. Especially with your end ileo, Pro, you shouldn't have an issue.
It sounds like you might be scared of what will happen if a whole pill tries to come through your stoma... the answer is that it will just come straight out! Once after my first surgery when I was taking Tylenol tablets (no coating whatsoever) I took one in the middle of the night with only a sip of water. A few hours later I saw the WHOLE THING in my bag. And this was a totally uncoated pill that would dissolve by itself in a cup of water! Anyway, no harm done, it just happens sometimes. As B'D said, worst case scenario you'll see it in your bag later and know you need to switch or change your routine.
