Pulmonary function changes after ethanolamine oleate injection VS band ligation in the treatment of esophageal varices

ABSTRACT

Introduction: The complications of injection sclerotherapy can be divided broadly into two categories, those occurring at the site of injection and those resulting from systemic dissemination of the sclerosant through the paraesophageal and azygos veins; this has been shown radiologically. Endoscopic variceal ligation [EVL] was developed as an alternative endoscopic method of treating esophageal varices with the anticipation that EVL would be as effective as EIS, but with fewer complications. We aimed in this study to assess the safety of both procedures for the lung
