In the 18-month period from January 2001 to July 2002, 1810 patients were admitted to the Prince of Wales Hospital with upper gastrointestinal bleeding. Among them, 1004 were found to have peptic ulcers. One hundred seventy-eight patients had active ulcer bleeding (spurting or oozing), and 196 patients had nonactive bleeding ulcer with visible vessel or clot. Of these 196 patients, 162 were recruited for the study and 34 were excluded. Among the latter group, 18 did not provide consent, 4 had had previous gastrectomy, 3 had terminal malignant disease, 5 had had previous endoscopic therapy within 30 days, 1 had a perforated ulcer, 1 with a clot had bleeding provoked by endoscopic manipulation before randomization, 1 had gastrointestinal bleeding of unknown origin, and 1 had disseminated intravascular coagulation. Six patients in whom malignant ulcers were subsequently confirmed were excluded after randomization (Figure 1).
