[Recurrent secondary stomach ulcer in a boy 3 months of age with osteogenesis imperfecta].

A case is described where a 3-month-old boy who had osteogenesis imperfecta with multiple fractures presented with vomiting and bleeding. A gastric ulcer was diagnosed by endoscopy but could not be visualized by repeated radiography. In spite of adequate treatment with H2-antagonists and antacids the bleeding recurred three months later. Development of hypertrophic pyloric stenosis was diagnosed and pyloromyotomy was performed after which the patient recovered without further recurrences. This case suggests that multiple ulcerogenic factors should considered and treated in pediatric patients with recurrent secondary ulcers in spite of appropriate treatment.
