A case of gastric outlet obstruction secondary to antral web in a preterm infant born at 25 weeks gestation is reported. The diagnosis was suspected on plain abdominal radiograph performed postnatally to confirm position of the umbilical catheters. On the initial radiograph (at age 1 h), a dilated stomach with a gasless abdomen was noted. A repeat chest and abdominal radiograph performed 24 h later due to increased ventilatory requirements showed persistence of this finding and upper gastrointestinal obstruction was suspected. An upper gastrointestinal contrast study confirmed the diagnosis of gastric outlet obstruction. The infant underwent a curative pyloroplasty on day 11 of life. The postoperative course was uneventful.
