In this study, the usefulness of rotating arm radiography on endoscopic injection sclerotherapy(EIS)in 16 patients with esophageal varices was evaluated. In this procedure, a short exposure time of less 20 msec was required. Subtraction of an X-ray image was difficult due to the difficulty of long time breath-holding during EIS therapy. Varicearography as digital information was obtained from several points at 1.5 degree intervals. Image halation was dealt with by using various filters. This procedure allowed three-dimensional observations of the esophageal varices which had complex branches at the lower esophagus and cardia of the stomach. In this way, the precise route of the feeding vessels could be evaluated. As a result, overdose-injection of sclerotic agents and serious complication could be prevented. Thus, the rotating radiography is safe and efficient tool for EIS.
