Acute hemorrhagic incarceration of prolapsed gastric mucosa.

In some patients with hiatus hernia, vomiting may propel a plug of redundant gastric mucosa into the distal esophagus, where it becomes incarcerated and engorged. Significant bleeding may result. Reduction of the hernia controls the hemorrhage. Endoscopy after the acute episode may demonstrate a gastric mucosal lesion considered to be characteristic of the syndrome.
