Congenital anomalies of the diaphragm. Personal experience with thirty-five consecutive cases.

A personal experience of thirty-five consecutive patients with congenital anomalies of the diaphragm is reported. The anomalies included twenty-five Bochdalek hernias, seven diaphragmatic eventrations, and three esophageal hiatal hernias. Except for the patients with esophageal hiatal hernias, virtually all patients presented with respiratory embarrassment, twenty-seven of the thirty-five within 24 hours of birth. An especially high mortality is associated with this early onset of symptoms. The treatment was surgical with a thoracic approach used for right Bochdalek defects and eventrations, and an abdominal approach used for left Bochdalek hernias. The importance of proper preoperative and postoperative management in a well equipped neonatal intensive care unit is emphasized.

Watery diarrhoea and ganglioneuroma with secretion of vasoactive intestinal peptide.

A young girl presenting with diarrhoea and stridor was found to have a thoracic ganglioneuroma. The tumour, which was partially resected, contained an abnormally high amount of vasoactive intestinal peptide (VIP) as measured by radioimmunoassay. This decreased after the operation. In addition, analysis of urine showed the presence of abnormal amounts of catecholamines and catechol metabolites. The findings suggest that the diarrhoea in the syndrome of ganglioneuroma and bowel dysfunction is due to an excess of VIP secreted by the tumour.
