Postural Syncope and Constipation: An Unusual Presentation of a Duodenal Dieulafoy’s Lesion

الملخص EN

Dieulafoy lesions are a rare etiology of gastrointestinal bleeding from a large caliber-persistent tortuous submucosal artery.

They account for 1-2% of all causes of acute gastrointestinal hemorrhage with 80%–95% of these lesions located in the stomach along the lesser curvature.

One-third of these lesions present at an extragastric location, with the proximal duodenum accounting for 15% of them.

We present a 21-year-old male with no significant past medical history or risk factors, who presented with repeated syncopal episodes followed by hematemesis, found to have a Dieulafoy lesion located at the duodenal bulb.

This lesion was diagnosed and successfully treated via upper endoscopy with epinephrine injection and the application of 2 endoscopic clips.
