Prepyloric antral diaphragm: delays in treatment.

Six cases of prepyloric antral diaphragm were encountered at Children's Hospital Medical Center of Akron between 1965 and 1985, with approximately 150 cases reported in the literature during this time. In our series, a delay from onset of symptoms to treatment existed for a period of 4 months to 6 years. We suggest that prompt endoscopic confirmation and surgical therapy for this lesion, when suspected by clinical and radiologic abnormalities, would decrease the physical and psychologic morbidity of unexplained recurrent vomiting in these children.
