Computer-based colonoscopy simulation (CBCS) is being utilized in endoscopy training with little evidence that it improves patient-based colonoscopy performance.
In this pilot study, researchers from the Mayo Clinic, Rochester, determined whether CBCS training improves the patient-based colonoscopy skills of gastroenterology (GI) fellows.
The research team evaluated competency at colonoscopy by comparing 4 novice GI fellows who had completed a 6-hour CBCS curriculum with 4 novice fellows had not.

The supervising faculty measured a number of parameters for each colonoscopy.
The team found that simulator-trained fellows outperformed traditionally trained fellows during their initial 15 colonoscopies in all performance aspects except "insertion time".
They determined that simulator-trained fellows inserted the endoscope significantly further and reached the cecum independently nearly twice as often during the early training period.
Furthermore, they found that simulator-trained fellows showed a continued advantage in 3 of the measured parameters for up to 30 colonoscopies.
Beyond 30 procedures, there was no difference in the performance of the 2 groups.
Drs Robert Sedlack and Joseph Kolars concluded, "A 6-hour CBCS curriculum provides an early training advantage by enhancing competency at the early stages of patient-based colonoscopy".
"These advantages are negligible after approximately 30 patient-based procedures".
"CBCS-enhanced training may allow faculty to be more efficient with their colonoscopy practice".
