Abstract
We retrospectively studied far the relationship between the diameter of solitarygastric varices (Lg)and the amount of injected alpha-cyanoacrylate monomer(CA)in 18 patients with solitary Lg who were examined by endoscopic uitrasonography (EUS) beforeand after EIS. Endescopie findings of Lg in 18 patients were F2 in g and F3 in 9. Lg was displayed as an aechoic area in the third layer of the stomach wall by EUS.The maximum short axis of the aechoic area was measured as Lg diameter. The mean Lgdiameter of solitary gastric varices with F3 was 5mm or more and significantly larger thanthat of F2 (P< 0.05). A positive correlation was observed between the diameter of Lg andthat of vein penetrating through the stomach wall (r=0.49), However, no correlation wasobserved between F factor and the diameter of penetrating veins. Asignificant correlation was observed between the volume of CA injected into Lg anddiameter of Lg measured by EUS(r=0.65)in 14 of 18 patients. Six cases were less than5mm in Lg diameter rneasured by EUS. Three of 6(50%)cases with Lg diameter less than5mm were treated with CA and the others were treated with 5%ethanolamine oleate. Onthe other hand, 11 of 12(91.6%)cases with Lg diameter more than 5mm were treated with CA alone. Therefore, Lg of 5mm or more in diameter should be jnjected with CA. Measuring Lg diameter on EUS before EIS is useful for selection of sclerosants, especially CA and for determining the volume of CA to be injected.
