We recently read with interest the article, “Novel frontiers of agents for bowel cleansing for colonoscopy”. This is a practical narrative review, which could be of particular importance to clinicians in order to improve their current practice. Although we appreciate the venture of our colleagues, based on our in-depth analysis, we came across several minor issues in the article; hence, we present our comments in this letter. If the authors consider these comments further in their relevant research, we believe that their contribution would be of considerable importance for future studies.

Core Tip: Colonoscopy is the gold standard investigation for the detection and treatment of colorectal neoplasia. The effectiveness and safety of the procedure mainly depends on the quality of bowel preparation (BP). Although international guidelines underline methods to ensure adequate BP, inadequate BP occurs in approximately one-third of the colonoscopies. The search for an ideal regimen to improve BP remains. The article by the authors addressed this issue successfully, but we detected several minor issues. Therefore, we would like to share our views and opinions on this interesting review.
