Outcome
Ottawa bowel preparation, adenoma, constipation
SECONDARY, ADENOMA
The primary outcome in this study was to compare the proportion of adequate bowel cleansing by using an Ottawa bowel preparation scale (OBPS) score ≤ 7 between split-dose PEG-ELS plus lubiprostone and split-dose PEG-ELS alone before colonoscopy in constipation patients. The secondary outcomes were the adenoma detection rate, safety profiles, and patient satisfaction with lubiprostone.
