Several factors are considered as the key indicators of quality colonoscopy, including endoscopist experience, withdrawal time, and quality of bowel preparation (BP). A number of laxatives are currently used as BP, and these are mainly based on PEG agents that differ for the volume and the addition of adjuvants. Several trials have demonstrated the efficacy and safety of low volume 2L-PEG based regimens compared with high volume PEG regimens and non-PEG agents. However, for low-volume 1L-PEG plus ascorbate (1L-PEG-Asc) only the data from registration trials are available, and none of these have been performed in an "open access" colonoscopy booking system. The aim of our study was to evaluate the safety and tolerability of 1L-PEG-Asc compared to 2L-PEG plus ascorbate (2L-PEG-Asc) in an "open access" booking system.

Safety of BP was assessed by reviewing the number of admissions to the Emergency Department of our Hospitals and the main presentation symptom/diagnosis in the 7 days following the colonoscopy.
