We studied 12 patients using endoscopic injection sclerotherapy (EIS) guided by endoscopic color Doppler ultrasonography (ECDUS). The ECDUS was performed with a PENTAX FG‐32UA (7.5MH2, convex type) and a HlTACHl EUB 565 as a display machine. The EIS needle, as well as changes in intramural blood flow before and after EIS were clearly observed with the ECDUS. When the sclerosant was injected properly into the esophageal varices, the blood flow in the esophageal varices could not be detected with color Doppler flow imaging nor with fast‐Fourier transform (FFT) analysis. Therefore EIS was safely performed with an adequate volume of sclerosant having been accurately injected into the varices. Of the disadvantages of this technique, the forceps channel was found to be a bit narrow, and the anterior view was somewhat oblique. Even so, EIS guided by ECDUS is surely a promising method for the treatment of esophageal varices, especially once the technical difficulties are overcome. (Dig Endosc 1994; 6 : 39–44)
