STUDIES ON THE PATTERN OF ENDOSCOPIC VARICEALOGRAPHY DURING INJECTION SCLEROTHERAPY(EVIS)

Abstract

Over the last 10 years, 100 patients with esophagogastric varices have been treated by endoscopic injection sclerotherapy(EIS)in our medical department. We analyzed 87 cases here in which endoscopic varicealography were performed during the first endoscopic intravariceal scleratherapy. We classified the endoscopic varicealographic findings into four groups; I : common type, II:instantly disappering type, III:interrupted type, IV:retrograde disappering type, and analysed the 87 cases according to these four criteria. Seventy four patients (85.1%) were classified as type I, 5patients (5.7%)as type II, 5patients(5.7%)as type III, and 3 patients(3.4%)as type IV. The therapeutic effectiveness of the EIS was studied fer each of these four EVIS groups. The effectiveness for type I was 93.2%and for type IV was 66.6%. However, the effectiveness for the type II and III was low in all cases. This study suggests that varicealography is an important technique for performing endoscopic sclerotherapy. Our classification on image aspects gives us the possibility of knowing the dynamics of local flood circulation of the varices, which is an important factor in predicting the therapeutic effectiveness of sclerotherapy.
