Brief summary

The aim of the study is to record and analyze endoscopist and endoscope motions to identify key movements in flexible endoscopy.

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 in flexible endoscopy.

Interventions

PROCEDUREMotions during gastroscopy

Recording of endoscopist and endoscope motions right after the endoscopic exam the patient came for. The endoscope is removed halfway up the esophagus and inserted into the pylorus to the descending duodenum. The gesture is repeated three times.

Design outcomes

Primary

MeasureTime frameDescription
Body motions recordingAt time of endoscopyBody 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 recordingAt time of endoscopyEndoscope motions recording using the Aurora electromagnetic tracking system (NDI, Waterloo, Canada) inserted in the endoscope operating channel. The Aurora electromagnetic tracking system is designed for tracking tip and orientation of rigid and flexible endoscopes. The system consists of an electromagnetic field generator and a probe carrying the captors.
Endoscope wheels rotation recordingAt time of endoscopyExternal video recording of the endoscope wheels rotation.
Endoluminal images recordingAt time of endoscopyEndoluminal images recording using the endoscopic camera.
