  1. Continuous variables are presented as mean ± standard deviation. The t-test was used to compare continuous variables. Bolded values indicate statistical significance (p < 0.05).
  2. The “Easy handling (Motor only)” item was assessed only in the motorized endoscopy group. Lower scores indicate better outcomes in the operability score.
  3. ME motorized endoscope, CE conventional endoscope.
