title: Estimation of lungs' hypoplasia on postoperative chest x-rays in congenital diaphragmatic hernia.
abstract: Since we stopped inserting ipsilateral underwater chest drains after surgical reduction of the herniated contents in congenital diaphragmatic hernia, both lungs are allowed to expand at their own pace, making it possible to estimate their degree of hypoplasia on postoperative chest x-rays. Thirty-nine consecutive series of postoperative chest x-rays were examined by an independent reviewer in a blind manner and classified into three groups: none to mild pulmonary hypoplasia (group I, 10 cases); moderate to severe (group II, 20 cases); and very severe hypoplasia (group III, 9 cases). Correlations were done among groups and available anatomical and clinical data. Eight patients out of 9 survived in spite of very severe hypoplasia on postoperative chest x-rays, suggesting that indexes of severity may be misleading when they mistake pulmonary hypoplasia for the cause of death.
