Evaluation of Reduced-volume PEG Bowel Preparation Administered the Same Day of Colonoscopy (LowVolumePEG)
The conventional total dose of 4 L of polyethylene glycol (PEG) given the day before the procedure is safe and effective. It has been the standard cleansing regimen for the last 25 years. To overcome the difficulty in completing the bowel preparation due to large volume and/or taste, reduced-volume (mixed) bowel preparation of bisacodyl and 2 L of PEG have been shown to provide adequate colon cleansing and better tolerability.
LoVol-esse is a reduced-volume PEG-based bowel preparation to be used in combination with bisacodyl and designed to improve patient tolerability and attitude toward bowel cleansing prior to colonoscopy thanks to the reduced volume and improved taste. The present study is intended to compare the new dosing regimen of the bowel lavage solution given the same day compared with standard PEG formulation (SELG 1000) given the day before colonoscopy.

Detailed Description
A polyethylene glycol (PEG) electrolyte lavage solution (PEG-ELS) was originally developed in 1980 by the Fordtran group as isosmotic preparation for minimal water and electrolyte exchange with plasma to ensure safe cleansing of the bowel through a mechanical effect of large-volume lavage. The conventional total dose of 4 L given the day before the procedure is safe and effective and has been the standard cleansing regimen for the last 25 years. To overcome the difficulty in completing the bowel preparation due to large volume and/or taste, reduced-volume (mixed) bowel preparation of bisacodyl and 2 L of PEG-ELS have been shown to provide adequate colon cleansing and better tolerability.
In the last recent years, time of preparation has been demonstrated to be a critical factor for bowel preparation for colonoscopy. Several studies have demonstrated that reducing the time interval between the completion of bowel preparation and the exam improves colon cleansing compared with standard dose regimen of the PEG-electrolyte solution given the day before colonoscopy. At the same time manufacturers have tried to improve the taste and palatability of PEG formulations by adding suitable ingredients such as ascorbic acid or citric acid. LoVol-esse is a reduced-volume PEG-based bowel preparation to be used in combination with bisacodyl and designed to improve patient tolerability and attitude toward bowel cleansing prior to colonoscopy thanks to the reduced volume and improved taste. The present study is intended to compare the new dosing regimen of the bowel lavage solution given the same day compared with standard PEG formulation (SELG 1000) given the day before colonoscopy.
The results of this study will tells us if the last-hour preparation is effective and offers adequate tolerability and compliance to be adopted in clinical practice.
