My son is diagnosed with mild hepatomegaly with enteritis is it serious?

TooLittleInformation: Hepato-megaly=hepatic (liver) + enlargement. Enter-itis=enteric organ (bowel) + itis="inflamation of". Thus these terms are only descriptive of what someone believes/sees on whatever basis. There is no good information within these descriptive words, however accurate on whatever basis, to better understand what is going on or likely to happen over time.
