Abstract
BACKGROUND AND AIM: The implementation rates of pediatric gastrointestinal endoscopy are increasing with advancements in the devices used and pediatricians' skills. 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. METHODS: 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. RESULTS: Responses were obtained from 445 facilities. The total number of pediatric gastrointestinal endoscopies was 37 447 and that of endoscopic examinations was 32 219 (86.0%), with esophagogastroduodenoscopy accounting for 18 484 cases; ileal colonoscopy, 11 936; endoscopic retrograde cholangiopancreatography, 389; wireless capsule endoscopy, 897; and balloon-assisted 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. CONCLUSION: 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.
