Hiatus Hernia
Introduction
Hiatus hernia is a protrusion of the stomach through the diaphragmatic hiatus. Most hernias are asymptomatic, but an increased incidence of acid reflux may lead to symptoms of Gastroesophageal Reflux Disease (GERD) . Diagnosis is by barium swallow. Treatment is directed at symptoms of gastroesophageal reflux disease if present. (See also Overview of Esophageal and Swallowing Disorders .)
