Aims Bowel cleansing quality is a key performance indicator for colonoscopy. In our study, we compared polyethylene glycol (PEG)-based bowel preparations (BPs) in terms of bowel cleansing quality, cecal intubation rate and patient compliance.

Methods From January 2019 to September 2020, data from all consecutive adult outpatients who underwent colonoscopy in our Digestive Endoscopy Unit were collected. In our “open-access” booking system, patients could choose one of the available BPs without preliminary counselling by a physician or a nurse. BPs included high-volume (4L) PEG, low-volume PEG [2L-PEG-citrate or 2L-PEG-ascorbate (Asc)] and very low-volume PEG (1L-PEG-Asc). Adequate and excellent BP quality was defined as Boston Bowel Preparation Scale (BBPS) score≥6 and≥8, respectively. Cecal intubation rate and compliance to full BP were also evaluated.

Results During the study, 6681 patients underwent colonoscopy in our Unit. Among them, 430 had taken 4L-PEG, 270 2L-PEG-citrate, 4069 2L-PEG-Asc and 1912 1L-PEG-Asc. Adequate BP was achieved in 89.3%, 93.0%, 93.7%, and 96.3%, while excellent BP was achieved in 49.0%, 51.1%, 57.2%, and 67.3% for 4L-PEG, 2L-PEG-citrate, 2L-PEG-Asc and 1L-PEG-Asc, respectively (1L-PEG-Asc vs other BPs, p<0.001). Cecal intubation was achieved in 91.9%, 91.4%, 94.1% and 95.7%% for 4L-PEG, 2L-PEG-citrate, 2L-PEG-Asc and 1L-PEG-Asc (1L-PEG-Asc vs other BPs, p<0.001). Compliance to full BP was achieved in 93.9%, 94.4%, 97.3%, and 96.4% for 4L-PEG, 2L-PEG-citrate, 2L-PEG-Asc and 1L-PEG-Asc (2L-PEG-Asc vs other BPs, p<0.001).
