Background & Aim: Dieulafoy's lesion is a rare cause of obscure gastrointestinal bleeding, accounting for approximately 6% of upper gastrointestinal bleeding cases. Common symptoms in affected patients include painless, intermittent, and severe bleeding. The primary diagnostic method is endoscopy, and failure to treat and manage this condition can be life-threatening. The purpose of this case report was to present a patient diagnosed with Dieulafoy's lesion.
Case presentation: In this study, a 39-year-old male patient presented to Imam Khomeini Hospital in Tehran with complaints of severe hematemesis and melena. He reported no history of medication use or previous illnesses. Notably, the patient's hemoglobin level was 5.5 g/dL. Following the physician’s orders, the patient was admitted, and after undergoing a third endoscopy, he was diagnosed with a Dieulafoy's lesion. Blood transfusion and supportive interventions were administered. After five days in the intensive care unit, the patient was discharged on foot. At the six-month follow-up after discharge, the patient’s general condition was good, and no complications were reported.
Conclusion: Early diagnosis, endoscopic management, and effective treatment of this lesion can prevent more serious complications and improve the chances of complete recovery in these patients.
