When a patient is compliant with bowel preparation instructions, but the preparation is inadequate, there are little data from controlled trials to guide the bowel preparation prescription for a repeat colonoscopy. Most practitioners switch to a different regimen or repeat the original preparation but add more laxatives. <\/p>\n\n\n\n
In a 4-center, Canadian randomized trial, patients who previously followed instructions but failed bowel preparation were randomized to receive 15 mg of bisacodyl followed by 4 L of polyethylene glycol (PEG) the day before colonoscopy plus 2 L of PEG the morning of colonoscopy versus 15 mg of bisacodyl followed by 2 L of PEG the day before and 2 L of PEG the morning of colonoscopy.<\/p>\n\n\n\n
The additional 2 L of PEG did not improve the rate of adequate preparation, which was 91.2% with 4 L total and 87.6% with 6 L total (P<\/em>=.44). The ability to consume 100% of PEG was 88.2% with 4 L versus 74.7% with 6 L (P<\/em>=.02). Willingness to repeat the preparation was higher among patients who consumed 4 L (91.2%) versus 6 L (66.2%) (P<\/em><.001).<\/p>\n","protected":false},"excerpt":{"rendered":" When a patient is compliant with bowel preparation instructions, but the preparation is inadequate, there are little data from controlled trials to guide the bowel preparation prescription for a repeat colonoscopy.
