Between February 1984 and September 1987, endoscopic embolization (EE) was performed in 26 patients with esophageal varices. The effects of EE were evaluated with endoscopic findings according to the general rules for recording endoscopic findings on esophageal varices as specified by the Japanese Research Society for Portal Hypertension.
1) When the result was regarded as effective if a patient had C_w., F₁, R-C sign (-), Li and Lm or disappearance of varices, the improvement was found in 66.7% for Color, 79.2% for R-C sign, 54.2% for Form and 45.8% for Location after EE.
2) Recurrence of varices was found in 50% of the patients (12/24) and 4 of 12 cases (33.3%) had rebleeding.
3) When the endoscopic findings before and after EE were compared between relapsed and unrelapsed cases, relapsed patients had more unfavorable endoscopic findings, furthermore, the extent of improvements was also worse than that of unrelapsed cases.
4) As complications, slight fever, dysphagia and epigastric pain were found in most cases, however, all were cured conservatively.
In conclusion, EE is useful and safety tool for the improvement of endoscopic findings of the patients with esophageal varices.
