The Influence of Endoscopic Injection Sclerotherapy on Organs Surrounding the Esophagus

Abstract: Endoscopic injection sclerotherapy (EIS) is widely accepted as a means of treating esophageal varices. However, various complications of EIS have been reported. To investigate the cause of chest complications after EIS, chest CT and bronchofiberscopy (BF) were carried out in patients undergoing EIS. A contrast medium was added to the sclerosant in a 1: 4 ratio, and a chest CT examination was performed 30 minutes after the EIS procedure. BF was performed before and after EIS.
