EC Clinical and Medical Case Reports

Hydrogen peroxide, at various concentrations, is used in several domestic, medical, and industrial installations due to its oxidizing properties. H₂O₂ can induce the generation of air bubbles in the portal venous system, in addition to causing symptoms related to irritation of the gastrointestinal system. We present the case of a 32-year-old patient with no notable medical history who experienced a burning sensation in the throat after accidentally ingesting three sips of a colorless and odorless liquid. It was determined that the liquid ingested by the patient was a solution of H₂O₂. A cervico-thoraco-abdomino-pelvic CT scan performed in our department revealed aeroportia, aerobilia in the common bile duct, and gastric wall pneumatosis.
