Abstract

Endoscopic color Doppler ultrasonography (ECDUS) is a method for detecting color flow images in blood vessels. We previously reported on the usefulness of ECDUS (convex-type scanning instruments with forward--oblique viewing) for evaluating the hemodynamics of esophageal varices. In the present study, we report the usefulness of new electronic radial ECDUS in cases of esophageal varices by comparison with convex-type ECDUS. Twenty-six patients with esophageal varices were identified and studied. The underlying pathologies of portal hypertension included liver cirrhosis (15 patients) and cirrhosis associated with hepatocellular carcinoma (11 patients). Endoscopic findings of esophageal varices were as follows: Cb, F3, and Ls varices in four patients; Cb, F2, and Lm varices in 21 patients; and Cb, Lm, and F1 varices in one patient. RC1 was observed in the esophagus in 14 of the 26 patients. RC2 was noted in 11 cases, and RC0 was seen in one patient. ECDUS was performed using a Pentax EG-3630UR (forward view) with a distal tip diameter of 12 mm. The instrument (electronic radial array) has a curved array scanning transducer with variable frequency (5.0, 7.5, 10.0 MHz). A Hitachi EUB 6500,8500 was used for the display, providing 27...Continue Reading
