Preliminary study of the operational training model with portable gastrointestinal endoscope
Objective To investigate the optimal training model for upper gastrointestinal endoscopy(UGIE)suit-able for medical workers in grassroots units.Methods The portable endoscope developed by our team and the simula-ted upper gastrointestinal model were used for UGIE training,compared with the traditional direct clinical endoscopy teaching mode.After 10 and 20 training hours of training,both groups,under the guidance of supervisory instructors,performed 3 human gastroscopy procedures separately.The operation time,number of standardized gastroscopy images were recorded,and the Global Assessment of Gastrointestinal Endoscopic Skills for Upper Endoscopy(GAGES-UE)were scored.The differences between the two groups were assessed.Results In each group,4 trainees completed the training and assessments.The trainees after 20 training hours in both groups performed better in all aspects than those trained for 10 training hours.After 10 training hours,the portable endoscope teaching group demonstrated shorter total UGIE times[(877.00±104.16)s vs(995.04±105.84)s,P<0.001]and higher GAGES-UE pharynx passage scores[(3.75±1.15)scores vs(3.13±1.08)scores,P<0.05]compared to the traditional teaching group.No significant statistical differences were found between these two groups in terms of standardized image collection counts,GAGES-UE total score and other sub-scores after 10 training hours.After 20 training hours,the portable endoscope teaching group had higher scores in GAGES-UE pharynx passage scores[(4.63±0.65)scores vs(3.13±1.08)scores,P<0.05]and clarity maintenance[(3.50±0.59)scores vs(2.75±0.61)scores,P<0.05].There were no significant differences in the total gastroscopy time,standardized image counts,GAGUES-UE total scores,and three sub-items between these two groups(P>0.05).Conclusion The novel teaching model for UGIE examination is superior to the traditional model in terms of passing through critical parts like pharynx.Meanwhile,the preliminary training for novel teaching model can be conducted outside the hospital,reducing patient cases needed for training.
