Treatment and study plan

Position change

Procedure

Patients will be randomly assigned to two groups: Control group (those who will receive standard colonoscopy without position changes) and Position change group (those who will undergo position changes during colonoscope withdrawal during colonoscopy). Subjects in position change group will be asked to shift into three different positions during colonoscope withdrawal.
