摘要
INTRODUCTIONBleeding from the upper gastrointestinal ( GI ) tract remains common ,with a reported annual incidence of up to 172 per 100 000 [1],which has of anything increased from earlier series. Case fatality was recently reported as 14%[2] ,which has probably not changed over several decades .These figures may reflect a rising proportion of elderly patients and increasing non 杝teroidal anti-inflammatory use ,but occur despite apparently better treatments and understanding of the underlying pathophysiology of peptic ulcer disease.
