It is well known that ingestion of low concentrations of hydrogen peroxide is usually nontoxic; this does not produce gas embolism and is only a mild irritant to the gastrointestinal tract. We report the case of a 25-year-old woman who ingested one mouthful of 3% hydrogen peroxide and presented to the Emergency Department with persistent vomiting and epigastric pain. The radiographic evaluation found portal venous gas emboli. In addition, upper gastrointestinal endoscopy performed 2 h after ingestion revealed diffuse hemorrhagic gastritis. She showed a decrease of hemoglobin concentration and a positive test result for occult blood in stool. She was observed for 14 days and discharged. Follow-up endoscopy showed erythematous gastritis. This case illustrates that a low concentration of hydrogen peroxide can cause portal venous gas embolism and severe gastrointestinal injuries even if only a small amount is ingested.
