An asymptomatic presentation of gastric outlet obstruction secondary to congenital antral web in an extremely preterm infant

Abstract

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.

Gastric antral webs in adults: A case series characterizing their clinical presentation and management in the modern endoscopic era

“…The diagnosis of GAW is suspected during esophagogastroduodenoscopy (EGD) if aperture size of the antrum does not vary with peristalsis and is confirmed by demonstrating a normal pylorus distal to the GAW. To date, the majority of cases have been reported in the pediatric population ranging from premature neonates to teenagers[2-4]. The first case in an adult patient was reported by Sames et al in 1949, and very few have been described in the last thirty years[5].…”
