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.

An NBVV is defined as “a pigmented protuberance in the ulcer.”2 The risk of further bleeding of an NBVV is 40% to 50%,3 which is less than active arterial spurting (55%-90%) but more than an …

2003年12月12日 · Background and Aims: Because non-bleeding visible vessels (NBVV) of gastric peptic ulcers have the potential to re-bleed, endoscopic hemostatic treatment may be …

The flattening of NBVV may be caused by vessel organization in ruptured blood vessels; thus, the contracted, flat vessels would be expected to have a low re-bleeding rate and good clinical...

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?

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 …

Background: Non-bleeding visible vessel (NBVV) in patients with bleeding peptic ulcer is associated with a high risk of rebleeding. The aim of this study was to define factors …

Centrally located, red, protruded NBVV were the most frequently observed type, followed by centrally located, black, flat NBVV. The total re-bleeding rate of all of the NBVV was 27.8%. …
