Abstract
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 shortcomings. Developments 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.
Core tip: Capsule endoscopy is progressing from a mode of passive bowel viewing to active intervention throughout the gastrointestinal tract. This review outlines advances in capsule mobility, in vivo position and orientation tracking, drug delivery, and characterization of capsule-bowel interaction that may aid in device development. Recent advances in capsule actuation schemes suggest that magnetic capsule manipulation is at the forefront of endoscopic research. Integration of proprioceptive capsule sensing may enable reliable capsule control with the potential to facilitate development of interventional devices. We expect to see clinical application of these technologies in coming years.
