Summary
The use of an endotracheal cuff on the esophagoscope improves the visualization and accuracy of diagnosis of esophageal varices. The addition of a modified endotracheal cuff to the flexible gastroscope with a movable tip enhances visualization of the lesser curvature of the antrum and of the pylorus. It is also of assistance in examining the posterior wall and the cardia of the stomach.
