| 9 | Application of robotic technologies in lower gastrointestinal tract endoscopy:A systematic review显示文摘BACKGROUND Conventional optical colonoscopy is considered the gold standard investigation for colorectal tract pathology including colorectal malignancy,polyps and inflammatory bowel disease.Inherent limitations exist with current generation endoscopic technologies,including,but not limited to,patient discomfort,endoscopist fatigue,narrow field of view and missed pathology behind colonic folds.Rapid developments in medical robotics have led to the emergence of a variety of next-generation robotically-augmented technologies that could overcome these limitations.AIM To provide a comprehensive summary of recent developments in the application of robotics in lower gastrointestinal tract endoscopy.METHODS A systematic review of the literature was performed from January 1,2000 to the January 7,2021 using EMBASE,MEDLINE and Cochrane databases.Studies reporting data on the use of robotic technology in ex vivo or in vivo animal and human experiments were included.In vitro studies(studies using synthetic colon models),studies evaluating non-robotic technology,robotic technology aimed at the upper gastrointestinal tract or paediatric endoscopy were excluded.System ergonomics,safety,visualisation,and diagnostic/therapeutic capabilities were assessed.RESULTS Initial literature searching identified 814 potentially eligible studies,from which 37 were deemed suitable for inclusion.Included studies were classified according to the actuation modality of the robotic device(s)as electromechanical(EM)(n=13),pneumatic(n=11),hydraulic(n=1),magnetic(n=10)and hybrid(n=2)mechanisms.Five devices have been approved by the Food and Drug Administration,however most of the technologies reviewed 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.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.CONCLUSION Significant progress in robotic colonoscopy has been made over the last couple of decades.Improvements in design together with the integration of semiautonomous and autonomous systems over the next decade will potentially result in robotic colonoscopy becoming more commonplace. | Harpreet Kaur Sekhon Inderjit Singh Emily Rose Armstrong Sujay Shah Reza MirnezamiColorectal Surgery The Royal Free Hospital London NWQG Hampstead United Kingdom | 2021 | World Journal of Gastrointestinal Endoscopy2021，13，12： | 0 |
