Inclusion Criteria: ． high-risk peptic ulcer bleeding. High-risk bleeding ulcers were defined as participants with stigmata of a bleeding visible vessels (eg, spurting, oozing), a non-bleeding visible vessels (NBVV) or adherent clot.4 A NBVV at endoscopy was defined as a raised red, red-blue or pale hemispheric vessel protruding from the ulcer bed, without active bleeding.
