All four infants survived, but were excluded from further analysis. Of the remaining 38 patients who presented within six hours of birth, one was a conjoined twin with left posterolateral diaphragmatic hernia in both twins. Associated anomalies . Clinical features and outcome. Preoperative blood gas and alveolar-arterial O 2 gradient in relation to outcome.
All values are mean SD and range.
Intraoperatively, both were found to have left posterolateral diaphragmatic hernia. They shared the same liver and were also attached at the pericardium anteriorally. They were separated and both hernias repaired, but soon after, both twins died. Four of our patients were not operated on and died prior to surgery. The clinical features of the survivors compared to the non-survivors are shown in Table 2.
