Upper Gastrointestinal Endoscopic Evaluation Following Household Sodium Hypochlorite Ingestion.

Endoscopy is generally speculated to be unnecessary in sodium hypochlorite (NaClO) ingestions; however, a significant number of endoscopic evaluations are still being performed when this chemical is ingested. Therefore, the aim of the current study was to compare the outcome and endoscopic findings between patients who had ingested household NaClO and those who had ingested other types of corrosives. This retrospective cohort study enrolled 137 patients with a history of corrosive substance ingestion admitted to a tertiary hospital.
