ARTICLE HIGHLIGHTS
Research background
Inherent limitations exist with conventional colonoscopy which may be overcome by a variety of next-generation robotically-augmented technologies.
Research motivation
Robotic technologies have the potential to transform lower gastrointestinal (LGI) tract endoscopy with long term, benefits for patients, endoscopists and the wider healthcare industry. High quality evidence is currently lacking in this field.
Research objectives
This review provides a comprehensive summary of recent developments in the application of robotics in LGI tract endoscopy.
Research methods
A systematic review of the literature was performed. Studies reporting on the use of robotic endoscopic technology in ex vivo colon models or in vivo animal and human experiments were included.
Research results
Of 37 studies were included of varying actuation modality. Five devices have been approved by the Food and Drug Administration, however the majority remain in the early phases of testing and development. Level 1 evidence is lacking at present, but early reports suggest that these technologies may be associated with improved pain and safety.
Research conclusions
Significant progress in robotic colonoscopy has been made over the last couple of decades. The reviewed devices appear to be ergonomically capable and efficient though to date no reports have convincingly shown diagnostic or therapeutic superiority over conventional colonoscopy.
Research perspectives
Future improvements in design together with the integration of semi-autonomous and autonomous systems over the next decade will potentially result in robotic colonoscopy becoming more commonplace.
