Computation description:Help on this term

The quality of the bowel preparation is based on the colonoscopist's ability to visualise the mucosa after retained stool and fluid have been suctioned away. Bowel preparation should be assessed using a validated assessment tool (see 'Comments' section for examples) or other standardised process. Colonoscopists should document the quality of the bowel preparation for each colonoscopy.

Presented as a percentage.
