Endoscopist and Endoscope Motions During Colonoscopy

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to record and analyze endoscopist and endoscope motions to identify key movements during colonoscopy.

Detailed Description
-----------------
The increasing development of interventional digestive endoscopy raises the challenge to teach and learn complex endoscopic procedures. Nowadays experts are facing the challenge of explaining precisely an elaborate choreography of movements performed during the procedure, while novices are confronted with a broad range of hand, wrist and shoulder movements each resulting in different endoscope responses. The teaching strategy of endoscopy could benefit from a dedicated motion library that would associate the endoscopist's motion and the consequent endoscope response. A simplified endoscopic language made of individual motions could greatly shorten the learning curve. The aim of the study is to record and analyze endoscopist and endoscope motions to identify key movements during colonoscopy.

| --- | --- |
| Experimental: Motions during colonoscopy<br>Recording of endoscopist and endoscope motions right after the endoscopic exam the patient came for | Procedure: Recording of endoscopist and endoscope motions right after the endoscopic exam the patient came for<br>* Carrying out the endoscopic procedure planned for the patient with the dedicated colonoscope which has magnetic coils over the entire length of the insertion tube. These magnetic coils generate a pulsed magnetic field at low frequency. These pulses are transmitted to an external receiver, refreshed at 15 images per second, then relayed to the processor to generate a 3D representation of the colonoscope next to it of the endoscopic image. There is no additional risk to the patient compared to current practice. Recording of endoscopist and endoscope motions right after the endoscopic exam the patient came for.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Body motions recording | Body motions recording using the Xsens tracking device. The Xsens motion tracking system consists of 17 wireless motion sensors that are applied with straps to the endoscopist without hindering natural movements. | At time of colonoscopy | 
| Endoscope motions recording | Endoscope motions recording using the ScopeGuide tracking system. Real-time visualization of the ScopeGuide system is possible thanks to integrated electromagnetic coils and an external sensor that generate a 3D representation of the colonoscope next to the endoscopic image. | At time of colonoscopy | 
| Endoscope wheels rotation recording | External video recording of the endoscope wheels rotation | At time of colonoscopy | 
| Endoluminal images recording | Endoluminal images recording using the endoscopic camera. | At time of colonoscopy |
