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.
