How is bleeding from a duodenal ulcer treated?

The treatment of bleeding duodenal ulcers mainly includes: 1. Medication: Use proton pump inhibitors (such as omeprazole) to inhibit gastric acid secretion, reducing gastric acid irritation to the ulcer surface. Hemostatic drugs (such as tranexamic acid) can also be used concurrently to control bleeding. 2. Endoscopic therapy: For patients with refractory or moderate bleeding, local hemostasis can be performed via endoscopy, such as injection of epinephrine, application of hemostatic clips, or electrocoagulation. 3. Interventional therapy: When necessary, interventional treatment of the left gastric artery or gastroduodenal artery may be performed to embolize small arteries supplying the lesion, achieving hemostasis. 4. Surgical treatment: For patients with severe bleeding unresponsive to medical and endoscopic treatments, surgical options such as partial gastrectomy may be considered to achieve rapid hemostasis. 5. General supportive care: Patients must strictly rest in bed and fast from food and water. Intravenous nutritional support and oxygen therapy may be necessary to maintain fluid and electrolyte balance and prevent hypoxia.
