Advances in colonic imaging: technical improvements in colonoscopy

摘要

Colonoscopy has been available since the early 1970s and has become critical to the diagnosis and management of colorectal disorders. Features of the modern colonoscope and its variants are discussed, including the role of paediatric and variable stiffness colonoscopes for difficult insertion. The place of magnetic endoscope imaging systems and simulators in routine colonoscopy and training are examined. Finally, several recent innovations are used to illustrate how colonoscopy may evolve in the future, including new takes on the current instrument as well as potentially revolutionary pain-free, technically-easy, robotic devices for examination of the bowel.
