Dieulafoy lesion (DL), also known as persistent caliber artery, is a rare vascular anomaly accounting for approximately 1%-2% of non-variceal upper gastrointestinal bleeding. It most commonly occurs in the stomach (74%), but may also involve the duodenum, colon, esophagus, and jejunum. Clinically, it is characterized by massive gastrointestinal hemorrhage, intermittent abdominal pain, hematemesis, and melena, potentially leading to hemodynamic instability. Risk factors include advanced age, male sex, and cardiovascular comorbidities. Pathogenesis remains uncertain, although associations with antral motility disorders and altered gastric blood flow have been described. Diagnosis is established through esophagogastroduodenoscopy, which is effective in up to 70% of cases. Treatment is based on endoscopic hemostatic techniques, including electrocoagulation, laser photocoagulation, and band ligation.
