A CLINICAL STUDY OF BLEEDING GASTRODUODENAL ULCER

Two hundred and eighty-seven patients with bleeding gastroduodenal ulcer who were admitted with the chief complaints of hematemesis and/or melena were clinicopathologically studied. The operation was performed in 155 (54.0%) patients. Bleeding rates were 78.0% in UL-II, 44.0% in UL-III, and 47.0 in UL-IV. The rates needed emergency operation were 76.5% in UL-II, 42.9% in UL-III and 46.6% in UL-IV. Both bleeding and emergency operation rates were higher in UL-II cases. From an examination of the diameter of exposed vessels in vascular stump-positive cases, the inner-to-outer diameter ratio of the vessels was significantly smaller in UL-II (0.074) compared to UL-IV (0.125) cases. This fact indicates that UL-II cases less frequently associate with intimal hypertrophy, and once the vessels are broken, thrombosis is hard to be formed, accordingly more efforts being demonded for its hemostasis.
