Characterize Differences in Force Patterns Used by Different Endoscopists and Trainee Endoscopists

Phase II Study of Evaluation of Handheld Colonoscopy Force Monitor by Expert and Trainee Endoscopists in the Performance of Colonoscopy

The study is to evaluate how doctors in training are different from very experienced doctors when using force to perform colonoscopy with a device that monitors the amount of force applied to the colonoscope during colonoscopy.

The study consists of two sequential observational studies designed to identify which instrument should be used to assess trainee performance and to quantify trainee skill development in performance of colonoscopy over the course of their training program.
