Robotic colonoscopes could potentially provide a comfortable, less painful andsafer alternative to standard colonoscopy. Recent exciting developments in thisfield are pushing the boundaries to what is possible in the future. This articleprovides a comprehensive review of the current work in robotic colonoscopesincluding self-propelled, steerable and disposable endoscopes that could bealternatives to standard colonoscopy. We discuss the advantages and disadvantagesof these systems currently in development and highlight the technicalreadiness of each system to help the reader understand where and when suchsystems may be available for routine clinical use and get an idea of where and inwhich situation they can best be deployed.

Colorectal cancer is the third most common cancer in men and the second most common cancer in women worldwide. Diagnosing colorectal has been increasingly successful due to advances in technology. Flexible endoscopy is considered to be an effective method for early diagnosis and treatment of gastrointestinal cancer, making it a popular choice for screening programs. However, millions of people who may benefit from endoscopic colorectal cancer screening fail to have the procedure performed. Main reasons include psychological barriers due to the indignity of the procedure, fear of procedure related pain, bowel preparation discomfort, and potential need for sedation. Therefore, an urgent need for new technologies addressing these issues clearly exists. In this review, we discuss a set of advanced endoscopic technologies for colorectal cancer screening that are either already available or close to clinical trial. In particular, we focus on visual-inspectiononly advanced flexible colonoscopes, interventional colonoscopes with alternative propulsion mechanisms, wireless capsule colonoscopy, and technologies for intraprocedural bowel cleansing. Many of these devices have the potential to reduce exam related patient discomfort, obviate the need for sedation, increase diagnostic yield, reduce learning curves, improve access to screening, and possibly avert the need for a bowel preparation.

Capsule endoscopy of the future: What's on the horizon?

引用

World Journal of Gastroenterology 2015年第37期21卷 10528-10541页

Capsule endoscopes have evolved from passively moving diagnostic devices to actively moving systems with potential therapeutic capability. In this review,we will discuss the state of the art, define the current shortcomings of capsule endoscopy, and address research areas that aim to overcome said *** in capsule mobility schemes are emphasized in this text, with magnetic actuation being the most promising endeavor. Research groups are working to integrate sensor data and fuse it with robotic control to outperform today's standard invasive procedures, but in a less intrusive manner. With recent advances in areas such as mobility, drug delivery, and therapeutics, we foresee a translation of interventional capsule technology from the bench-top to the clinical setting within the next 10 years.
