Neonate Congenital Bochdalek Hernia: A National Survey of Its Members by Korean Association of Pediatric Surgeons

This is a survey on congenital posterolateral diaphragmatic hernia, conducted by Korean Association of Pediatric Surgeons (KAPS). A registration form for each patient during the 5-year period between 2010 and 2014 and a questionnaire were sent to each member. Twenty-six members in 16 institutions returned completed forms. Total patients were 219. Prenatal diagnoses were done in 181 cases (82.6%). Preoperative mortality was 11.4%. Minimal invasive surgery was done in 61 cases (31.8%). Risk factors related with death were Apgar score, oxygenation index, preoperative pH and bicarbonate, O2 saturation, the presence of hernia sac, and the size of defect. The neonatal survival and 1-year survival of total patients were 77.6% and 75.3%.
