Background
: Upper gastrointestinal bleeding is the most difficult problems at emergency status and early accurate diagnosis and prompt emergent care is needed because of variable etiology and high mortality. We studied comparatively about relationship between upper gastrointestinal bleedings and it's prognostic factors.

Methods : We analyzed 42 cases that upper gastrointestinal bleeding from on Feb. 1992 to on Jan 1993 at hospital setting.

Results : Among the 42 cases, the ratio of the male to the female is 2.8 to 1, more common in the male and the 3rd decade is the most common. For the etiologic cause, peptic ulcer is the most common as 19 cass. The character of the bleeding is mixed type of hematemesis and hematchezia to 45.2%. The predisposing factors are alcohol abuse and drug.

Conclusion : The significant risk factors are the evidence of associated disease, increased bleeding tendency, decreased hematocrit and increased BUN. We conclude that these patients must be treated with early, active management and therapy.
