Gastric antral web
Abstract
Gastric antral web is a rare cause of gastric outlet obstruction with an incidence of 1 in 100,00 births. Only about 150 cases have been reported. Antral web is a thin fenestrated diaphragm made up of 2 layers of mucosa and usually lacking muscular component. Evidence of it being both of congenital or acquired cause has been reported, but the theory of localized endodermal proliferation during developmental stage is the most accepted. The most common presentation is of non-bilious vomiting and often diagnosed in infancy however diagnosis can be delayed due to non obstructive nature of symptoms. It is often misdiagnosed as infantile hypertrophic pyloric stenosis or pylorospasm. It can be confirmed with Barium enhanced radiographs of upper GIT, ultrasound and endoscopy. The non symptomatic antral web can be advised supportive measures but in the symptomatic group surgery is the treatment of choice. Antral web excision with or without pyloroplasty is done. It has good prognosis.
