Background:
Dieulafoy lesion is a calibre persistent submucosal artery associated with a minuter mucosal defect. Dieulafoy lesion has been reported to account for 1-5.8% of acute nonvariceal upper gastrointestinal bleeding in adults, but it is rarely reported in children.
Case:
Here we report a case of duodenal Dieulafoy lesion in a 13-year-old boy. After endoscopy and laparotomy, he still had no definite diagnosis and effective treatment. The duodenal Dieulafoy lesion was finally identified by selective angiography and was effectively treated by intravascular embolization.
Conclusions:
For unexplained upper gastrointestinal bleeding, the possibility of duodenal Dieulafoy lesion should be considered. A combination of multiple diagnosis and treatment methods can improve the success rate of diagnosis and treatment when a single test or treatment method cannot provide definitive diagnosis or effective treatment.
Insights
Dieulafoy lesions, a rare cause of upper gastrointestinal bleeding in children, can be challenging to diagnose. This case highlights the successful identification and treatment of a duodenal Dieulafoy lesion using angiography and embolization.
Area of Science:
- Gastroenterology
- Vascular Medicine
- Pediatric Surgery
Background:
- Dieulafoy lesions are characterized by a persistent submucosal artery and a small mucosal defect.
- They are an infrequent cause of acute nonvariceal upper gastrointestinal bleeding in adults (1-5.8%) and rarely reported in pediatric populations.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
