Bowel Preparation, Colonoscopy
Conditions
Brief summary
Bowel preparation is closely lined to the quality of colonoscopy, inadequate bowel preparation (IBP) could lead to higher miss rate of adenomas, patients' discomfort and higher health expense. For the patients with possible IBP before the examination, it may be better to cancel the colonoscopy and repeat bowel preparation through modified or enhanced strategies. This study aimed to externally validate the efficiency of a procedure-based model in predicting inadequate bowel preparation
Interventions
