Management and Therapeutic Considerations of Hydrogen Peroxide-Induced Necrotizing Gastroenteritis: A Case Report.

Necrotizing gastroenteritis is a rare but severe condition characterized by extensive inflammation and mucosal necrosis of the gastrointestinal tract. It is most commonly seen in neonates, infants, and immunocompromised individuals. We present a rare case of a 46-year-old female patient who developed necrotizing gastroenteritis following accidental ingestion of 3% hydrogen peroxide, manifesting as three days of epigastric pain, heartburn, and recurrent emesis. This report details the patient's clinical presentation, diagnostic evaluation, therapeutic strategies, and management course. The case emphasizes the importance of clinical suspicion, timely intervention, and consideration of both surgical and conservative treatment approaches, with particular attention to long-term functional complications and quality of life.
