As part of the Japan Pediatric Endoscopy Study Group, we aimed to investigate the rates of pediatric gastrointestinal endoscopy use and the associated adverse events through a nationwide survey.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A questionnaire was sent to 630 institutions in Japan. The numbers of pediatric gastrointestinal endoscopy cases and adverse events occurring during endoscopy, from April 2011 to March 2016, were investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Responses were obtained from 445 facilities. The total number of pediatric gastrointestinal endoscopies was 37\u00a0447 and that of endoscopic examinations was 32\u00a0219 (86.0%), with esophagogastroduodenoscopy accounting for 18\u00a0484 cases; ileal colonoscopy, 11\u00a0936; endoscopic retrograde cholangiopancreatography, 389; wireless capsule endoscopy, 897; and balloon\u2010assisted enteroscopy, 513. The number of endoscopic treatments was 5228, followed by balloon dilatation (1703), foreign body removal (989), and polypectomy (822); 201 adverse events (0.54%) occurred, 79 of which presented during endoscopic examination (0.25%). Eight serious perforations were noted in 0.0054% and 0.025% of those undergoing esophagogastroduodenoscopy and colonoscopy, respectively. Overall, 122 adverse events (2.33%) occurred in association with endoscopic treatment. One case of cardiopulmonary arrest occurred because of accidental extubation. However, no deaths occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Endoscopic examinations had a slightly higher adverse event rate, because of an increase in endoscopic retrograde cholangiopancreatography and small intestine enteroscopy, than that reported in previous studies, but the adverse event rate of endoscopic treatment did not increase.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jgh.15297","type":"journal-article","created":{"date-parts":[[2020,10,31]],"date-time":"2020-10-31T08:25:06Z","timestamp":1604132706000},"page":"1545-1549","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Nationwide survey of pediatric gastrointestinal endoscopy in Japan"],"prefix":"10.1111","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4708-8049","authenticated-orcid":false,"given":"Takahiro","family":"Kudo","sequence":"first","affiliation":[{"name":"Department of Pediatrics Juntendo University Faculty of Medicine  Tokyo Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daiki","family":"Abukawa","sequence":"additional","affiliation":[{"name":"Department of General Pediatrics and Gastroenterology Miyagi Children's Hospital  Sendai Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1992-6834","authenticated-orcid":false,"given":"Yoshiko","family":"Nakayama","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Shinshu University School of Medicine  Matsumoto Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Segawa","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery Tokyo Women's Medical University Hospital  Tokyo Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2272-3755","authenticated-orcid":false,"given":"Keiichi","family":"Uchida","sequence":"additional","affiliation":[{"name":"Department of Gastrointestinal and Pediatric Surgery Mie University Graduate School of Medicine  Tsu Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6317-4305","authenticated-orcid":false,"given":"Keisuke","family":"Jimbo","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Juntendo University Faculty of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0364-0022","authenticated-orcid":false,"given":"Toshiaki","family":"Shimizu","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Juntendo University Faculty of Medicine  Tokyo Japan"},{"name":"The Pediatric Gastrointestinal Endoscopy National Survey Working Group in Japanese Pediatric Endoscopy Research Group  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,31]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2015.06.028"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/17474124.2017.1321986"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2013.08.014"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0000000000001408"},{"key":"e_1_2_8_6_1","first-page":"83","article-title":"Pediatric gastrointestinal endoscopy: European Society of Gastrointestinal Endoscopy (ESGE) and European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) guideline executive summary","volume":"49","author":"Tringali A","year":"2017","journal-title":"Endoscopy"},{"key":"e_1_2_8_7_1","first-page":"267","article-title":"Complications of gastrointestinal endoscopy","volume":"29","author":"Nagashima K","year":"1993","journal-title":"J.
