What is the treatment for bleeding duodenal ulcer?

Endoscopy is the first-line treatment. Even with larger ulcers, endoscopic hemostasis can be achieved in the majority of cases. Surgery is clearly indicated in patients in whom arterial bleeding cannot be controlled at endoscopy. Angiographic embolization is an alternate option, particularly in those unfit for surgery.

What is given initially in bleeding duodenal ulcer?

Operation for Bleeding Duodenal Ulcer. The first priority during an emergency operation for a bleeding duodenal ulcer is control of the bleeding site. If EGD has failed to identify the source of hemorrhage, a longitudinal pyloroduodenotomy is necessary to inspect the duodenal bulb and gastric antrum.

How do you fix a perforated ulcer?
