[Gastric devascularization for acute gastric mucosal lesion and bleeding].

Thirteen patients with acute gastric mucosal lesion and bleeding were treated with gastric devascularization. Of all, 11 apparently stopped bleeding, two failed to respond to the procedure, one rebled, and three died. Clinical analysis of the patients suggested that low blood pressure, damage of liver function, serious infection, acidosis and uremia were precipitating factors of the disease and for AGML in portal hypertension, the effect of this procedure was poor. Meanwhile, the etiology and pathological mechanism of AGML, the selection of operation types for the disease, and the anatomical and physiological bases of gastric devascularization were also discussed.
