Clinical Evaluation of the Multi‐bending Scope in Various Endoscopic Procedures of the Upper Gi Tract

Abstract

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.

Endoscopic submucosal dissection for gastric neoplasms by using a novel attachment device—a one-sided, expandable balloon

“…The M-scope can be effective for observation and EMR in these situations. 8,9 Although the M-scope is useful for observation and endoscopic treatment, it has the disadvantage of being heavier and rather larger in diameter, with reduced maneuverability, than conventional endoscopes.…”

A novel handmade “multi-bending endoscope system” for endoscopic submucosal dissection of difficult-to-approach superficial gastric neoplasms

“…Early gastric cancers are frequently detected at the lesser curvature of the gastric body, but ESD of lesions in this area may be challenging because of the difficult approach. A multi-bending endoscope is a good option for such a situation [1], but it is not widely used owing to its limited purpose and relatively high cost. We therefore developed a handmade multibending system and used it to perform ESD for 12 difficult-to-approach lesions located at the lesser curvature of the gastric body.…”
