In clinical toxicology, gastric endoscopic decontamination is rarely used, and only a few cases of pharmacobezoar removal after intentional ingestion of slow-release drugs have been described. Our case describes the use of gastric endoscopic decontamination to remove potential pharmacobezoar in an adolescent after ingestion of a lethal dose of isoniazid and rifampin, even long after gastric lavage. This technique allowed the removal of pharmacobezoars still present in the stomach while preventing further deterioration of the patient.
