[Bleeding in chronic refractory peptic ulcer].

The authors reviewed the clinical problems of the bleeding in refractory ulcers. Incidence of refractory and easily-relapsing ulcers are about 40% of all chronic ulcers and their bleeding rate seemed to be more than 10% of them. We discussed the relationship between bleeding and risk factors such as age, NSAID use, H. pylori infection, etc. The consideration to them is very important in the present time, being difficult to predict ulcer bleeding.
