Transnasal endoscopy has advantages of no sedation, less patient monitoring, less nursing time and less expense than conventional peroral gastroscopy. Transnasal endoscopy can be completed at the patient's first visit, with no sedation, no IVs and no extra personnel. Fujinon’s new super slim transnasal endoscope provides a high level of transnasal endoscopy. It has a 4.9 mm and a 5.9 mm distal tip diameter for improved insertion capability.
