Summary
High quality bowel preparation is essential for successful colonoscopy. This study aimed to
assess the impact of the dose of Polyethylene Glycol(PEG) on the quality of bowel
preparation. This prospective, endoscopist-blinded, randomized, controlled study was
conducted. 3L-group received 3 bags of PEG and were instructed to drink 1L at 19:00 in the
evening before the day of colonoscopy at a rate of 250 mL every 15 minutes, and to drink the
remaining 2L 4 to 6 h before colonoscopy at the same rate. 4L-group received 4bags of PEG and
were instructed to drink 2 L at 19:00 in the evening before the day of colonoscopy at a rate
of 250 mL every 15 minutes, and to drink the remaining 2L 4 to 6 h before colonoscopy at the
same rate. The primary outcome was the quality of the bowel preparation according to the
Boston Bowel Preparation Scale (BBPS). The secondary outcomes included polyp detection rate
(PDR), adenoma detection rate (ADR), tolerance, and subjective feelings of patients.
