We used endoscopic color Doppler ultrasonography to detect hemorrhagic gastric ulcer, and to determine whether this modality could show blood vessels present deep to ulcers and whether these vessels influenced clinical course. Subjects were 20 patients with hemorrhagic gastric ulcers which had visible vessels on the ulcer base endoscopically. In 11 of 20 patients (group P) color signals indicating blood flow were observed, in which a weak pulsatile wave was detected in five cases. In two operated cases the signals were confirmed as blood vessels histologically. The diameters of these vessels were over 0.35 mm. It was thought that in cases undetectable on endoscopic color Doppler ultrasonography (group N) the diameter of vessels was too narrow or the velocity of blood too slow. There were no differences in the clinical background of group P and group N. However, ulcer bleeding was more severe in group P cases (P < 0.05). Many patients in whom blood flow was detected experienced repeated ulcer bleeding as well as ulcer recurrences. Patients with hemorrhagic ulcers and in whom ultrasonic imaging demonstrates blood flow should be managed with great care.
