Percutaneous Endoscopic Gastrostomy: A Possible Trigger for Dieulafoy's Lesion.

Introduction: Upper gastrointestinal (GI) bleeding is a medical condition commonly seen in clinical practice due to variable etiologies and a multitude of presentations. The patients can present with hematemesis, melena, or hematochezia in case of severe bleeding. The initial evaluation should involve assessing the hemodynamic status with adequate resuscitation followed by diagnostic tests to identify the source and potentially treat it. Dieulafoy's lesion, sometimes referred to as Dieulafoy's disease, is a rare cause of upper GI bleeding with no clear risk factors, which makes it a diagnostic conundrum. Here we describe an unusual case of Dieulafoy's lesion developing following percutaneous endoscopic gastrostomy (PEG) placement. Case Presentation: We describe a case of a 70-year-old female patient with a past medical history of hyperlipidemia, well-controlled hypertension, and an ischemic cerebrovascular accident, which caused neurologic dysphagia and placement of a PEG tube 3 weeks prior. She presented to the emergency department due to melena, with hypotension of 90/50 mmHg, tachycardia of 126 beats/minute, and hemoglobin of 5.6 g/dl. An endoscopy revealed a Dieulafoy's lesion on the lesser curvature of the stomach just across the PEG tube, which was managed with epinephrine and hemoclips. Conclusion: This is a rare case of Dieulafoy's lesion on the lesser curvature of the stomach, potentially developing due to PEG placement.
