USEFULNESS OF MAGNETIC ENDOSCOPE IMAGING (MEI) FOR COLONOSCOPIC TRAINING ; SINGLE CENTER RANDOMISED CONTROLLED TRIAL

Aims Loop formation is a common event that occurs frequently during colonoscopy. The development of looping can cause pain and discomfort to the patient and make advancement of the colonoscope difficult. The magnetic endoscope imaging (MEI) is built in to show that with its use outcomes are improved during colonoscopy. Aim of this study is to evaluate the usefullness of the ScopeGuide Assist for trainee endoscopists with respect to the number of loop formation.

Methods This study included a randomized controlled trial of 70 patients who were undergoing a colonoscopy at the endoscopic units of the Korea university anam hospital from May 2021 to September 2021. Patients were randomized to either group ; SPG group vs. non-SPG group. 5 trainee endoscopists are included and used the Scopeguid. In non-SPG group, SPG monitor was hidden from view to the operator. The primary end point was the proportion of loop formation.

Results The study consisted of a total 70 patients, and the rate of loop formation was significantly less in the group using the Scopeguide. (SPG 62.9% vs non-SPG 88.6% ; p=0.012) The mean insertion time was 8.3+- 4.73 in the SPG group and 6.98+- 3.29 in the non-SPG group, and was not significant with a p value of 0.190. (SPG 22/35, 62.9% vs non-SPG 14/35 11.44% ; p=0.056) but position change showed significant difference between SPG group and non-SPG group. (SPG 0.0% vs non-SPG 11.4%, p=0.039)

Conclusions For the trainee endoscopists, use of MEI reduced the rate of loop formation in routine colonoscopy.
