ABSTRACT
Background: Computer simulators are being developed as a training tool in colonoscopy. We aimed to establish whether a computer simulator could differentiate between novices and experienced colonoscopists. Methods: Eight novice and 4 experienced endoscopists took part in the study. Novices (5 nurses, 3 junior doctors) had no previous practical endoscopy experience. Experienced endoscopists were senior doctors (2 consultants, 1 SpR) or nurse consultant (n = 1) (no previous significant simulator experience). All novices were given group teaching in principles of colonoscopy, functions of a colonoscope, and an introduction to the simulator (Immersion Medical). Both groups were given a standard practise case (SPC) with tutoring, then performed the standard test case (STC) without help. Insertion was terminated at 15 minutes if the caecum had not been intubated. Results: 7 novices (88%) and all experienced endoscopists achieved caecal intubation. Terminal ileal intubation (TII) was achieved in 3 novices (38%). At 5 min the novices were in sigmoid (n = 4) descending (n = 1) splenic flexure (n = 2), and transverse colon (n = 1); all the experienced had intubated the TI and were extubating. There was no difference in percentage time in "no discomfort" or in "moderate/severe discomfort" between the two groups. See Table. Conclusions: This simulator can differentiate between novices and experienced endoscopists, novices take longer to achieve caeca1 intubation and are less likely to achieve TII. However, not all parameters automatically measured by this colonoscopy simulator differentiate between them. Basic principles of colonoscopic insertion can be taught to novices using this simulator.
