- In the tailored group, high-risk patients are instructed to drink the first 2 L of Polyethylene Glycol (PEG) at 19:00-21:00 hours on the day before colonoscopy at a rate of 250 ml every 15 min. On the day of the procedure, they take another 2 L PEG 4-6 h before colonoscopy. The low-risk patients were given a standard dose of 2 L PEG 4-6 h before colonoscopy.
