Constipation is a common high risk factor for inadequate bowel preparation. The bowel cleansing efficacy of the standard split-does of 4L seems to be suboptimal in constipated patients. The investigator hypothesized that compared with the standard preparation regime, the split-dose with three times of 4L PEG may be superior in BP quality.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Split-dose of 4l PEG was used before and on the day of colonoscopy
Drug: Split dose of 4L PEG
Three times-dose of 4l PEG was used before and on the day of colonoscop of 4l PEG was used before and on the day of colonoscopy
Drug: Three times dose of 4L PEG
All patients were given oral instruction for bowel preparation on the day of appointment and re-instruction through phone call on two days before scheduled colonoscopy. They were instructed to have a regular lunch and take only clear liquid or low-residual food for the dinner on the day before colonoscopy. The participants began to drink the first 2 L of PEG at 7:00-9 PM on the day before colonoscopy at a rate of 250 mL every 15 minutes. On the day of the procedure, patients took the remaining 2 L 4-6 hours before colonoscopy.
The same as mentioned above. The participants began to drink the first 1.5 L of PEG at 2:00 PM and the second 1.5L of PEG at 8:00PM on the day before colonoscopy at a rate of 250 mL every 15 minutes. On the day of the procedure, patients take the remaining 1.0 L 4-6 hours before colonoscopy.
Rate of adequate bowel preparation
Adequacy of bowel preparation quality was defined as a total score ≥6 and each segmental score ≥2. The total scores included 3 scores of colonic regions: the right side, the transverse section, and the left side, which ranged from 0 to 9 (0= very poor, 9=excellent). For the unreached colon in incomplete colonoscopy, the segmental BBPS was scored as 0. The total and segmental scores were judged through videos by investigators who were familiar with the criteria and blinded to group allocation.

Started Sep 2017 (actual). Primary completion is estimated for Aug 2018, 11 months after the start.
Of 568 non-industry interventional studies with no phase under Health Behavior, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 33. This study's planned 11 months is below that.
Counting every sponsor, half of 586 studies reached it within 15 months; a quarter within 5 and three quarters within 32.
