An ultrasonic probe (miniture ultrasonic probe, UM-1W, Olympus) was used in this study. It had an external diameter of 3.4mm and a radial scan transducer with a frequency of 7.5MHz. Ultrasonography with the miniture ultrasonic probe was performed in 7 cases before and after endoscopic injection sclerotherapy (EIS) for esophageal varices.
Our technique of EIS is the para and intra-variceal injection of 1% aethoxysklerol (AS) . Low echo-lumen images absorbed before EIS where changed to high echo-ones from their circumference immediately after EIS. Also we observed that a part of collateral blood flow pathway of the extra walls which visualized as low echo-lumen images disappear.
The followings were pointed out as important usefulness of a miniture ultrasonic probe.
1) Observation of the esophageal varices before and after EIS, under endoscopically visual control.
2) Performed EIS exactly, at the same time.
3) We could grasped collateral blood flow pathway of the extrawalls noninvasible.
