A prospective study in a group of severely bleeding ulcer patients with active arterial bleeding, NBVV and adherent clot, showed that DUP–based endoscopic treatment provided a …

We found that white, protruded and peripherally located NBVV in gastric ulcers have a higher chance of re-bleeding if preventive endoscopic hemostatic procedures are not performed.

How do we evaluate the risk of re-bleeding from various NBVV in gastric peptic ulcers to determine which types should be treated by endoscopy to prevent re-bleeding?

The reason why the peripherally located NBVV in gastric ulcers are associated with higher re-bleeding rates is not presently clear. We speculate three possible reasons.
