Gastric outlet obstruction secondary to antral mucosal diaphragm.

Gastric antral mucosal diaphragm is an entity that is probably more common than is reported in the literature. A large number of patients with antral gastric mucosal diaphragms remain asymptomatic. When symptomatic, the diagnostic mainstays at this time consist of barium contrast studies complemented by flexible endoscopy. Awareness of the endoscopic appearance of a gastric mucosal antral web can aid in its diagnosis at endoscopy. Surgical treatment is reserved for those patients with gastric outlet obstruction and can range from simple excision of the web to gastric resection and reanastomosis. A case report emphasizing diagnostic and treatment modalities is presented.
