Advances in multibending endoscope: A paradigm shift in minimally invasive diagnostics and therapeutics.

Abstract

Digestive endoscopy has been widely used in the diagnosis and treatment of digestive diseases. However, the anatomical complexity of specific lesions increases the difficulty of these operations, resulting in complications or treatment failure. Although various strategies, such as floss traction and the application of transparent caps, have been explored, their effectiveness remains limited due to individual differences in patients' anatomical characteristics. The multibending (MB) endoscope represents a significant innovation as it is a conventional endoscope with an additional bending section and dual channels. Currently, this technology has been applied in gastroscopy, duodenoscopy and peroral cholangioscopy. The bending part of the endoscope facilitates its passage into difficult-to-reach anatomical regions and improves operating angles, thereby enhancing surgical precision and efficiency while reducing complication rates. Furthermore, the dual-channel design accelerates procedural workflows and increases operational versatility. This innovation is poised to transform endoscopic diagnosis and treatment of digestive system diseases. Since the MB endoscope is relatively new, further research is needed to comprehensively explore its benefits for and potential in endoscopic diagnosis and treatment. The aim of this review is to summarize the current research, indications, and future directions of MB endoscope.
