Abstract
A 3-day-old male presented with dyspnea and was diagnosed as congenital diaphragmatic hernia (CDH). He was referred to our hospital and we stabilized the respiration with high frequency oscillation under the deep sedation. On the fifth day of life, he had melena. We suspected an incarcerated CDH and planned an emergency operation. At exploration he was found to have a left diaphragmatic hernia with the small bowel incarcerated. The bowel was not necrotic, and the defect was closed primarily. He had an uncomplicated recovery. Because a CDH which appears more than 24 hours after birth may have a narrow orifice, particularly with gastrointestinal symptoms, we should take account of incarceration.
