| [ Summary ] | Transnasal esophagogastroduodeniscopy (TN-EGD) techniques have rapidly improved. However, there are several problems with endoscopic diagnosis using TN-EGD as compared to transoral EGD. In the pharyngeal region, observation is very easy because of a low incidence of gag reflex difficulties. On the other hand, differential diagnosis is difficult because it is impossible to use iodine staining or NBI-magnification. In the esophagus and the stomach, image enhanced endoscopy with iodine and indigocarmine dye-staining is very useful. Biopsies must be conducted when employing NBI magnification. | |
