The Effectiveness and Tolerability of a Very Low-Volume Bowel Preparation for Colonoscopy Compared to Low and High-Volume Polyethylene Glycol-Solutions in the Real-Life Setting.

ABSTRACT: Adequate bowel cleansing is essential for high-quality colonoscopy. Recently, a new very low-volume 1 litre (1L) polyethylene glycol (PEG) plus ascorbate solution (ASC) has been introduced. Our aims were to assess the effectiveness and tolerability of this product compared to low-volume 2L PEG-ASC and high-volume 4L PEG solutions, in a real-life setting. In six endoscopy units in Sweden, outpatients undergoing colonoscopy were either prescribed solutions according to local routines, or the very low-volume solution in split dose regimen. Bowel cleansing effectiveness and patient experience was assessed using the Boston Bowel preparation scale (BBPS) and a patient questionnaire. A total of 1098 patients (mean age 58 years, 52% women) were included. All subsegment and the total BBPS scores were significantly greater for 1L PEG-ASC in comparison to other solutions (p < 0.05 for 1L PEG-ASC and 4L PEG for transverse and left colon, otherwise p < 0.001). Nausea was more frequent with 1L PEG-ASC compared to 2L PEG-ASC (p < 0.001) and vomiting were more often reported compared to both other solutions (p < 0.01 and p < 0.05 for 2L PEG-ASC and 4L PEG, respectively). Smell, taste, and total experience was better for 1L PEG-ASC compared to 4L PEG (p < 0.001), and similar compared to the 2L PEG-ASC. In conclusion, 1L PEG-ASC leads to better bowel cleansing compared to 2L PEG-ASC or 4L PEG products, with similar or greater patient satisfaction.

Project description:BackgroundAlthough both high- and low-volume polyethylene glycol (PEG) are widely used in intestinal preparation before colonoscopy, there is still controversy over the superiority of their cleaning effects. This meta-analysis sought to explore the safety and effects of high-volume PEG solution and low-volume PEG mixed solution on intestinal cleanliness before colonoscopy.MethodsThe PubMed, EMBASE, and Cochrane Library databases were searched to retrieve relevant articles on the effects of high- and low-volume PEG mixture solutions on intestinal cleanliness from the inception of the databases to October 15, 2022. Two independent researchers screened the literature according to the predetermined inclusion and exclusion criteria, and extracted the required data separately. A bias risk assessment was conducted for each study using the relevant tools in the Cochrane Handbook. The included data were subjected to a meta-analysis using R 4.2.1 software.ResultsThis article includes a total of 15 studies involving a total of 5,847 patients. There was no difference in the cleanliness score, qualified rate of intestinal cleanliness and patient compliance between the high- and low-volume group. The patients in the low-volume PEG mixed solution group had a higher repeat willingness bowel cleansing rate than those in the high-volume PEG group [risk ratio (RR) =0.71, 95% confidence interval (CI): 0.62-0.82, P<0.01]. Compared with the low-volume group, the incidence of adverse reactions such as nausea, vomiting, and abdominal pain increased in the high-volume group (RR =1.38, 95% CI: 1.22-1.56, P<0.01; RR =1.79, 95% CI: 1.41-2.27, P<0.01; RR =1.05, 95% CI: 1.01-1.08, P<0.01).ConclusionsIn the pre-colonoscopy preparation method for patients, although the high-volume PEG and low-volume PEG mixed regimen have similar effects on intestinal cleanliness, the low-volume mixed regimen has a higher willingness to repeat and a lower incidence of adverse reactions. In clinical practice, considering patient compliance and safety, a low-volume mixed regimen may be a more optimal option.
