Clinical evaluation of the multi-bending scope in various endoscopic procedures of the upper GI tract

The multi-bending scope is one of the technological innovations that is making possible new techniques in endoscopic diagnosis and treatment. The multi-bending function makes it easier to approach sites that would be hard to reach with conventional scopes. Not only is this useful for observation and biopsies of difficult-to-approach sites, it is also expected to be very useful in various endoscopic treatments such as endoscopic submucosal dissection, endoscopic mucosal resection, and endoscopic hemostasis. Unfortunately, despite these obvious advantages, the incorporation of multifunctionality and high image quality results in a heavier and wider scope with reduced maneuverability. For practical clinical use, a balance between functionality and maneuverability is essential. We believe that making further improvements in this area is crucial to the successful development of this technology.
