Sponsor's own description
Colonoscopy is the considered gold standard for diagnosing diseases in the colon. A colonoscopy is normally divided into the insertion from anus to cecum, the technical difficult part, and a retraction or diagnostic part. No objective measure exists to evaluate the performance of a colonoscopy. Based on a movement analysis of the colonoscope we wish to seek evidence for an automated and objective system able to differentiate between endoscopists with various experience in a clinical setting. The movement analysis is based on information's from the colonoscope. Electromagnetic coils are built in along the length of colonoscopes. They generate a pulsed magnetic field that is picked up a receiver coil. The data-points for each coil are inserted into an algorithm for the movement analyzing. This analysis is done as a change between the tip of the scope, and the next tracked magnetic coil. The result is a relative movement of the colonoscope in relation to the previous position. The study is conducted a three different University Hospitals in Denmark. Twenty physicians with experience in colonoscopy are voluntary included. Patients appointed to a screening colonoscopy are included and a minimum of five consecutive colonoscopies are recorded for each physician. We predict the system to be automated and objective tool correlated with the physician's technical level of expertise in clinical colonoscopy.
