Recentrly, Doppler color flow imaging (DCFI) equipment, especially for abdominal use, has improved remarkably. But no litrature shows its utility in gastric lessons.
This time, we improved abdominal DCFI equipment (SSA-270A, Thoshiba co-op) so as to perform 7.5 MHz linear scanning Color Doppler endoscopic ultrasonography (as follow CD-EUS) and to evaluate gastric lesions.
13 chronic gastritis cases, 4 gastric ulcers (Ul IV) cases, 11 gastric cancer cases (3 early cancers, 8 advanced cancers) and 3 healthy volunteers are as follows:
1) In healthy volunteer cases, subserosal gastric wall blood flow (700 ∼ 1500 μ) and proprial muscle layer blood flow (100 ∼ 400 μ) could be observed.
2) In chronic gastritis cases and gastric ulcer cases, only subserosal gastric wall blood flow could be displayed by CD-EUS.
3) All fully examined gastric cancer cases showed tumor blood flow, and the velocity, was measured easily.
4) CD-EUS, which gives us new diagnostic information for gastric cancer, can be established as an important diagnostic method for gastric lesions (especially scirrhous legions) in the near future.
