Antral Web with Characteristic Appearance in Gastroscopic and Barium Study in an Eight-year-old Girl

Abstract
|
|
|
Antral web (prepyloric mucosal diaphragm) is a rare gastric anomaly that disturbs the gastric outlet and has sometimes been a diagnostic problem to the radiologist and the endoscopist. It is composed of mucosa that enclose a membrane of submucosa
and
located at the antrum on varible distances from the pylorus. Web is congenital in origin but may be secondary to chronic peptic ulcer disease. Obstructive symptoms may not occur when diaphragmatic aperture is larger than l centimeter in diameter.
The
diagnosis of web relies on the history, barium study and gastroscopic findings but it may be noticed after laparotomy.
We experienced an antral web which demonstrated characteristic endoscopic and radiologic findings in an eight-year-old girl. These typical distinguishable findings in endoscopic and barium study in this case can remind of the antral web in
patients
with
gastric outlet obstruction symptoms. Antral web or pyloric web, although rare, should be considered in the differential diagnosis of upper gastrointestinal obstructive symptoms in patients of any age.
