In the United Kingdom, acute bleeding from peptic ulcer is estimated t
o account for 25 admissions to hospital per 100 000 population annuall
y. Overall mortality has been reported at around 10%. Accurate initial
assessment for the identification of high risk groups, prompt resusci
tation. close monitoring and timely intervention for rebleeding improv
es survival. In patients not responding to initial resuscitation and t
hose who rebleed, emergency endoscopy identifies the source of bleedin
g in the majority and is essential to enable endoscopic therapy. Injec
tion of a vasoconstrictor and/or sclerosant into a visible or bleeding
vessel, or thermal coagulation, reduces the incidence of rebleeding a
nd probably decreases mortality. In general terms, 'early' surgical in
tervention is indicated for those aged over 60 years in whom bleeding
recurs or continues despite endoscopic measures. The low mortality (<5
%) reported from specialist units and units adhering to strict protoco
ls of management should become the norm. The use of antacids, histamin
e H-2-receptor antagonists or omeprazole does not influence mortality
or the incidence of early rebleeding in patients with acute haemorrhag
e from peptic ulcer. Although not used routinely, tranexamic acid has
been shown to have significant benefit.
