ABSTRACT
This report presents a case of a 16-year-old male with severe upper gastrointestinal bleeding caused by a Dieulafoy lesion (DL). A DL is a rare but life-threatening condition characterized by sudden and massive bleeding from a small arterial vessel in the gastrointestinal (GI) tract. Diagnosis is often made through esophagogastroduodenoscopy (EGD), which reveals an enlarged submucosal blood vessel. The patient was successfully treated with adrenaline injection and hemoclipping during EGD. This case highlights the importance of considering a DL as a potential cause of severe upper GI bleeding in pediatric patients and emphasizes the significance of early recognition and intervention to achieve favorable outcomes. Additional investigation is required to enhance our comprehension of the occurrence, etiology, and most effective approaches to managing DLs in pediatric patients.
