Problem:
Extradistestinal disease seems to prefer to "bowel" diseases, I think this is about diseases outside gastrointestinal tract so stomach.
Consider diseases ulcerative colitis and Crohn's disease (enteritis) as examples. Colitis affects to colon, outside of small intestine, I think extraintestinal therefore. Crohn's disease (enteritis) however affects to the small intestine so I would think intestinal disease (but this clause is wrong) - it should be at least have extraintestinal manifestations.
Required:
Question: What is the exact definition of the word extra in intestinal diseases?
Does anyone know how to go about this search to explain it.
