[Neonatal gastric necrosis].
BACKGROUND: Neonatal necrotizing gastritis is rare. It is usually a complication of acute anoxia or shock and its diagnosis is essentially radiological. CASE REPORTS: Case no. 1: a boy was born at the 36th week of a pregnancy complicated by preeclampsia. Perinatal asphyxia necessitated delivery by cesarean section. He presented with neonatal respiratory distress which was complicated by pneumothorax. On the 5th day of life, the abdomen was distended and the newborn had still not been fed. On the 6th day, X-rays showed pneumatosis of the gastric wall associated with pneumoperitoneum. Surgery showed an area of necrosis on the posterior surface of the stomach with a small perforation, which was stitched. The child was fed 5 days later and was in good condition at the age of 6 months. Case no. 2: a girl was born at the 35th week of a pregnancy complicated by asthma during the second trimester. Perinatal asphyxia and abnormal fetal rhythm led to delivery by cesarean section. At 24 hour of life, she vomited blood and fibroscopy confirmed the presence of blood in the stomach. On the 3rd day, blood vomiting appeared again, associated with abdominal distension. X-rays showed pneumatosis of the gastric wall; fibroscopy showed necrosis of the lower 2/3 of the stomach. Feeding was stopped and the child was given cimetidine. Refeeding was possible when the girl was 10 days old, and she was in good condition at the age of 6 months. CONCLUSION: Neonatal gastric necroses and necrotizing enterocolitis have many similar features. Medical therapy is often effective, but surgery is mandatory when necrotizing gastritis is complicated by perforation.
