However, evidence for the efficacy of a CLD in bowel preparation is lacking, which led us to question whether it is reasonable to recommend a CLD for 24 hours prior to colonoscopy as part of a PEG-based bowel preparation in healthy outpatients. 20 - 22 Currently, a dietary regimen incorporating a CLD for at least 24 hours is recommended for improving the quality of preparation. 9 - 19 Only a few studies have evaluated the effects of different diet types on bowel preparation under controlled circumstances.
CLEAR LIQUIDS BEFORE COLONOSCOPY FULL
Moreover, patients usually complain of having to adhere to a clear liquid diet (CLD) for a full day before the colonoscopy in addition to the large volume (4 L) of the preparation.Īlthough diet restriction is an important factor influencing patient compliance, the majority of previous studies regarding bowel preparation have focused on comparing the effects of different purgative regimens, including the types, timing, and quantities of cathartics. 8 However, the need to ingest a large volume of fluid reduces patient compliance. Polyethylene glycol (PEG) has become the most commonly used agent for colon cleansing because it does not cause fluid exchange across the mucosal membrane and thereby limits fluid and electrolyte disturbances.

5, 6 In response, professional societies have proposed measuring the quality of bowel preparation as an important quality indicator for colonoscopy. 4 Several studies have reported that poor bowel preparation reduces detection of polyps that may have the potential to be cancerous. 2, 3 One of the main reasons for missed CRCs is incomplete bowel cleaning. 1 However, early studies have shown that 4% to 5% of cancers may be missed on a single colonoscopic examination.
