Filho ECC, et al. - Experts attempted to estimate the accuracy, interobserver agreement and safety of the transnasal ultrathin compared to conventional endoscopy in patients with cirrhosis. The enrollment comprised of consecutive patients referred for screening or surveillance of oesophageal varices. The prevalence of oesophageal varices and high-risk oesophageal varices were discovered to be 59% and 29% respectively. It was deduced that the unsedated transnasal endoscopy was safe. This procedure displayed an excellent accuracy and high interobserver agreement for the identification of oesophageal varices and for determining the high-risk varices in cirrhotic patients.
