[The surgeon's procedure in acute gastrointestinal hemorrhages of tumor etiology].

The authors observed 353 patients with acute gastro-intestinal hemorrhages of tumorous etiology. It was shown that modern methods of diagnosis could reveal the correct cause and localization of the source of hemorrhage in 97.5% of patients and objectively estimate the degree of blood loss. The individual methods of treatment enabled the general lethality to be reduced to 29.8% and after radical operations to 7.5%.
