Abdominal Binder in Colonoscopies Performed by Trainees

This randomized trial will be conducted to evaluate the effectiveness and safety of an abdominal binder use during colonoscopy performed by gastrointestinal endoscopy fellow trainees. The investigators hypothesized that the abdominal binder use would facilitate and increase the effectiveness of the colonoscopy for inexperienced operators.
