CURRENT STATE OF THE ART OF NEW IMAGE-ENHANCED ENDOSCOPY

Abstract

A new image processor called EVIS X1 was introduced in 2020. It integrates novel image-enhanced endoscopic images, texture- and color-enhanced imaging (TXI), and red dichromatic imaging (RDI). TXI has been shown to improve the visibility of neoplastic lesions in the gastrointestinal tract and is expected to improve the lesion detection rate in clinical practice. Owing to its unique principle allowing easier visualization of bleeding points, RDI has been found to reduce the psychological stress of endoscopists compared with white-light imaging, especially for intraoperative bleeding during ESD. The usefulness of RDI for hemostasis in gastrointestinal bleeding other than ESD should be investigated in the future.

The development of new endoscopic processors and image-enhanced endoscopy is expected to provide evidence for daily practice and to advance gastrointestinal endoscopic diagnosis and treatment.
