Endoscopic examination for duodenal ulcer bleeding during transcatheter arterial embolization: Analysis of two cases

Endoscopy is usually effective in treating duodenal ulcer bleeding, but depending on the lesion site and overall patient condition, hemostasis may be difficult to achieve with endoscopy alone. We described two patients with duodenal ulcer bleeding in whom endoscopic hemostasis was difficult. Immediately after transcatheter arterial embolization, endoscopic examination was used to confirm hemostasis and completing of the angiographic procedures.
