Abstract:Background and Aims: Because non-bleeding visible vessels (NBVV) of gastric peptic ulcers have the potential to re-bleed, 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. Therefore, we have evaluated 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. Methods: A total of 227 NBVV in 202 patients with gastric peptic ulcers that were endoscopically followed without endoscopic hemostatic procedures were classified by the following factors: vessel color, form, location of the NBVV in the ulcer crater, and location of the ulcer in the stomach. The re-bleeding rate was then analyzed for each type of NBVV. Results: Significantly high rates of re-bleeding were observed in cases with white, protruded and peripheral NBVV. In particular, white NBVV located in the peripheral zone of the ulcer crater were frequent re-bleeding sources. The location of the ulcer in the stomach was not a statistically significant factor in determining re-bleeding rates. Conclusion: 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.
