Adequate bowel preparation is essential to ensure the quality and safety of colonoscopic examinations; however, data on the current practices in Japan remain limited. This study aimed to clarify the current status of bowel preparation, use of bowel\u2010cleansing agents, and associated challenges among physicians performing colonoscopies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In March 2026, we conducted a nationwide web\u2010based cross\u2010sectional survey of physicians performing colonoscopies in Japan. The survey assessed bowel preparation practices, use of bowel\u2010cleansing agents, constipation, and renal function before colonoscopy. Responses were obtained from 300 physicians who performed at least 10 colonoscopies per month.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Low\u2010volume polyethylene glycol (PEG) plus ascorbate preparations were the most commonly used bowel\u2010cleansing agents, followed by high\u2010volume PEG preparations and magnesium\u2010based agents. Cleansing efficacy and safety were the most highly valued characteristics of bowel\u2010cleansing agents. 64.7% of physicians reported that the perceived frequency of inadequate bowel preparation was &gt;10% among their patients. Although 64.3% of the physicians reported always assessing constipation, only 32.7% reported always evaluating renal function before colonoscopy. Compared with hospital\u2010based physicians, those working in clinics reported a significantly lower proportion of inadequate bowel preparation, but a significantly lower rate of renal function assessment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although cleansing efficacy and safety are prioritized in bowel preparation for colonoscopy in Japan, physicians perceived inadequate bowel preparation to occur in a substantial proportion of patients. Thus, further optimization of bowel preparation strategies and more consistent assessment of renal function before colonoscopy are needed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>University Hospital Medical Information Network (UMIN000060808).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/deo2.70398","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T07:21:21Z","timestamp":1786432881000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Current Status of Bowel Preparation for Colonoscopy in Japan: A Web\u2010Based Survey of Endoscopists (PRESS Survey)"],"prefix":"10.1002","volume":"7","author":[{"given":"Takayuki","family":"Matsumoto","sequence":"first","affiliation":[{"name":"Department of Internal Medicine Division of Gastroenterology, School of Medicine Iwate Medical University  Yahaba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motohiro","family":"Esaki","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Division of Gastroenterology, Faculty of Medicine Saga University  Saga Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumihito","family":"Hirai","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Faculty of Medicine Fukuoka University  Fukuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minami","family":"Umeyama","sequence":"additional","affiliation":[{"name":"Medical Department EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Medical Department EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiki","family":"Takatsuki","sequence":"additional","affiliation":[{"name":"Medical Department EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Shimada","sequence":"additional","affiliation":[{"name":"Pharmaceutical Development Department Data Science Group, EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Oota","sequence":"additional","affiliation":[{"name":"Pharmaceutical Development Department Data Science Group, EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masato","family":"Ueno","sequence":"additional","affiliation":[{"name":"Medical Department EA Pharma  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1159\/000543921"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21763"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21660"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.13972"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2021.6238"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.15002"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2020.12.031"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2019.12.031"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2022.11.031"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2025.02.010"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.14914"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.3389\/fgstr.2022.946459"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12876\u2010026\u201004674\u2010z"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.14309\/ajg.0000000000003073"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/jebm.12607"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10620\u2010023\u201008089\u20108"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncpneph0939"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1055\/a\u20100959\u20100505"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(11)61176\u20108"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1055\/s\u20100043\u2010120569"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572\u20100241.2005.40885.x"},{"key":"e_1_2_12_23_1","unstructured":"GBD Chronic Kidney Disease Collaboration.Global Regional and National Burden of Chronic Kidney Disease 1990\u20132017: A Systematic Analysis for the Global Burden of Disease Study 2017.
