Study Arms:
- Arm 1: Colonoscopy 6 minute withdrawal time (Type: ACTIVE_COMPARATOR): -Undergo colonoscopy with the standard 6-minute withdrawal time followed by a tandem colonoscopy of at least another 6-minute withdrawal time.
- Arm 2: Colonoscopy 9 minute withdrawal time (Type: EXPERIMENTAL): -Undergo a 9-minute withdrawal time followed by a tandem colonoscopy with at least the standard 6-minute withdrawal time.
- Arm 3: Colonoscopy 12 minute withdrawal time (Type: EXPERIMENTAL): -Undergo colonoscopy with a 12-minute withdrawal time followed by a tandem colonoscopy with at least the standard 6-minute withdrawal time
