Umbilical hernia of stomach.

Herniation of the stomach through the umbilicus is exceedingly rare with only one case reported in the international literature in the past 40 years. One case of a reducible gastric umbilical hernia, not diagnosed by endoscopy, is reported. Diagnosis was made by double-contrast barium examination after 5 years of symptoms and ineffective treatment. Herniation of the stomach is difficult to diagnose by endoscopy and radiological studies can be more sensitive and allow a more specific diagnosis.
