Endoscopist and Endoscope Motions During Colonoscopy

Not Applicable

Completed

• Conditions: Intestinal Disease; Colonic Diseases
• Interventions: Procedure: Recording of endoscopist and endoscope motions right after the endoscopic exam the patient came for

• Registration Number: NCT04263818
• Lead Sponsor: IHU Strasbourg

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.

Primary Outcome Measures

Name	Time	Method
Body motions recording	At time of colonoscopy	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.
Endoscope motions recording	At time of colonoscopy	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.
Endoscope wheels rotation recording	At time of colonoscopy	External video recording of the endoscope wheels rotation
Endoluminal images recording	At time of colonoscopy	Endoluminal images recording using the endoscopic camera.
