Non-bleeding visible vessels (NBVV) in gastric peptic ulcers have the potential to re-bleed. Therefore endoscopic hemostatic treatment may be necessary during the first emergency endoscopy.
However, not all NBVV re-bleed, and endoscopic hemostasis sometimes causes fatal side-effects.
In this study, physicians from Japan evaluated the risk of re-bleeding from various NBVV in gastric peptic ulcers. The team determined which type of vessels should be treated by endoscopy to prevent re-bleeding.
They classified 227 NBVV in 202 patients with gastric peptic ulcers.

The team recorded vessel color, form, and location in the ulcer crater, as well as location of the ulcer in the stomach.
They assessed the re-bleeding rate for each type of NBVV.
The physicians found that significantly high rates of re-bleeding occurred in cases with white, protruded and peripheral NBVV.
White NBVV located in the peripheral zone of the ulcer crater were frequent re-bleeding sources.
However, the team found that the location of the ulcer in the stomach was not a statistically significant factor in determining re-bleeding rates.
Dr Amano's team concluded, "White, protruded and peripherally located NBVV in gastric ulcers have a higher chance of re-bleeding if preventive endoscopic hemostatic procedures are not performed".
