Magnetic flexible endoscope for colonoscopy: an initial learning curve analysis.

Area of Science:

• Medical Devices
• Robotics
• Gastroenterology

Background:

• Colonoscopy is a complex procedure demanding extensive training.
• Traditional colonoscopes can cause patient discomfort and trauma.
• A novel magnetic flexible endoscope (MFE) was developed for easier maneuvering.

Purpose of the Study:

• To evaluate the learning curve of the MFE.
• To assess user experience with the MFE.
• To compare MFE performance against a pediatric colonoscope (PCF).

Main Methods:

• Novices, experienced endoscopists, and MFE users performed trials on a model colon.
• Comparison between MFE and PCF using block randomization.
• Cecal intubation success, time to cecum, and NASA task load index were measured.

Main Results:

• All novices and experienced endoscopists achieved MFE minimum proficiency.
• MFE average proficiency was reached by most novices and experienced endoscopists.
• PCF proficiency was achieved by only one novice; MFE use reduced novice workload.

Conclusions:

• The MFE exhibits a short learning curve for inexperienced users.
• Proficiency with the MFE is attainable in a limited number of trials.
• The MFE offers a reduced perceived workload and enhanced user experience.
