Abstract
INTRODUCTION: Dieulafoy's lesion, a rare but life-threatening condition accounting for a small percentage of acute gastrointestinal bleeding cases, has historically posed diagnostic and therapeutic challenges. CASE PRESENTATION: In this article, we present two cases that required surgical intervention due to unsuccessful attempts with endoscopy. Case 1 involved a 40-year-old patient with a history of treated duodenal ulcers, while Case 2 featured a 74-year-old woman with no notable medical history. Both patients exhibited severe bleeding, necessitating urgent surgical procedures. The surgical approach involved wide gastrotomy, careful inspection, and successful suturing of the bleeding vessel. DISCUSSION: Dieulafoy lesions, discovered by French surgeon Georges Dieulafoy in 1885, constitute 1-2 % of acute gastrointestinal bleeding cases. These anomalies involve enlarged submucosal arteries, predominantly in the stomach, but occurrences in other sites are documented. Endoscopic methods, surpassing surgical intervention, are preferred for treatment, boasting success rates over 90 %. Surgical measures become a last resort for uncontrolled bleeding, with laparoscopic surgery emerging as a minimally invasive alternative, facilitated by various intra-operative localization techniques. Laparoscopic wedge resection, in particular, exhibits lower re-bleeding rates than traditional oversewing methods, although feasibility depends on lesion location. CONCLUSION: While endoscopic methods are preferred, surgery remains a vital option when bleeding persists or endoscopic intervention fails. This report highlights the significance of surgical management in selected cases of Dieulafoy's lesion.
