There were no statistically significant differences between the PICO and 2 L PEG-ELS groups in adequate bowel cleansing rate (92.2% vs. 91.3%, P = 0.437) and polyp detection rate (42.2% vs. 45.5%, P = 0.096). However, the PICO group achieved a better performance in the BBPS scores of the total [(6.90 ± 1.19) vs. (6.81 ± 1.14), P = 0.016] and the right colon [(2.15 ± 0.53) vs. (2.11 ± 0.51), P = 0.005] compared to the 2 L PEG-ELS group. In terms of adverse reactions, the 2 L PEG-ELS group reported more nausea (11.7% vs. 5.7%, P < 0.001) and the PICO group reported more sleep disturbances (24.5% vs. 14.6%, P < 0.001), but the willingness to repeat the procedure with the same regimen was similar high in the 2 L PEG-ELS and PICO groups (99% vs. 99.2%, P = 0.588).</p><p><strong>Conclusion: </strong>In this prospective observational study, both PICO and 2 L PEG-ELS are safe and effective options for bowel cleansing in the Chinese population.</p>","PeriodicalId":9129,"journal":{"name":"BMC Gastroenterology","volume":"25 1","pages":"164"},"PeriodicalIF":2.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11899895/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143613334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
