[Postoperative follow-up of cardia function in newborn infants after esophageal, diaphragmatic and abdominal wall abnormalities].

From 1986 to 1989 46 newborn were examined after correction of oesophageal atresia, defects of diaphragm or abdominal wall, to record postoperative cardial insufficiency. In 15 of 40 long-time pH metry analysis (37.5%) and in 11 of 22 x-ray studies (50%) a pathological result was found; in 8 times these findings were followed by operation and in 8 times by conservative therapy. pH metry is suitable even in very small newborn for postoperative screening of cardial function; if the results are positive, x-ray examination is supplementary to diagnosis and therapeutical planning.
