Perforated stress ulcers in infants.

During a 5-yr period, 10 infants less than 1 yr of age developed gastroduodenal perforation during treatment for severe underlying illness. Brisk gastrointestinal hemorrhage preceded perforation in most patients. In contrast to stress ulceration in adults, infants appear to have a higher frequency of single ulcers, perforation, and duodenal (rather than gastric) location. The mortality of 40% in this group, and in those patients reported in the literature who have been treated since 1960, implies that effective preventive and therapeutic measures are not yet available and also emphasizes the serious nature of the underlying disorder.
