baby with digestive issues - off an on vomiting and distended stomach with constipation. Scan showed a mass initially but after a GI tube was inserted to aleviate gas, palpatation of stomach and sonagram showed nothing. Mothers milk was fed, baby did fine - eating small amounts but fine. Dr. then tried hypo-allergenic formula and baby s stomache became bloated again with obvious pain and discomfort. Doctors are stumped - remarked this is rare and they are not sure how to treat.
