Wider use of endoscopic hemostasis in upper gastrointestinal bleeding (UGIB
) has reduced significantly the: need for operation. Nevertheless, surgery
still plays a pivotal role. Failure to control bleeding endoscopically shou
ld not delay surgery when necessary, and a close cooperation between endosc
opists and surgeons is essential. Initial endoscopy ton thr bleeding in app
roximately 94% of patients and helps to identify, these patients with a hig
h or low risk of rebleeding. High-risk patients should be examined for rebl
eeding by clinical and endoscopic assessment within at least the first 2-3
days. Large ulcers are the most likely to rebleed, and in elderly patients
with severe comorbidity showing little or no healing tendency, they benefit
from repeated fibrin glue treatment. Tn cases of rebleeding despite initia
l endoscopic hemostasis and conservative treatment. another attempt to stop
the hemorrhage endoscopically is justified in most patients. A subgroup of
patients who are old, suffering from hypotension due to rebleeding, with l
arge ulcers and several other illnesses should undergo surgery immediately
because endoscopic intervention often fails, and these patients deteriorate
quickly. The surgical procedure should be limited to safe hemostasis.
