T1616: Ultra-Thin High Resolution Endoscopy in the Diagnosis of Early Gastric Cancers

Ultra-thin videoendoscopy (outer diameter less than 6 mm) have been developed, can easily be passed transorally or transnasally without sedation, and have been shown to be well tolerated and accurate. Unsedated esophagogastroduodenoscopy (EGD) can provide an efficient, cost-effective alternative to standard endoscopy, should be useful for endoscopic screening, and can be offered as an option to conventional sedated examination. However, the resolutinon of ultra-thin videoendoscopy was lower than that of conventional endoscopy. Recently, Ultra-thin high resolution endoscopy was developed .
