Utility of Diagnostic Colonoscopy in Pediatric Intestinal Disease.

Abstract

Background: The roles and methods of diagnostic colonoscopy in pediatric patients were previously demonstrated. With advances in medical equipment and the increasing need for pediatric endoscopic diagnosis, we compared recent results with those previously reported. Methods: A retrospective analysis was conducted on pediatric patients aged ≤15 years, comparing those who underwent their first diagnostic colonoscopy between 1 January 2007 and 28 February 2015 with those who did so between 1 March 2015 and 28 February 2022 at Kurume University Hospital. Results: A total of 274 patients were included, including 110 in the previous study and 164 in the present study. The main indications were hematochezia in the previous study (63/110, 57.3%) and abdominal pain in the present study (64/164, 39.0%). Ulcerative colitis (74/274, 27.0%) was the most common diagnosis in both studies. The major difference from the previous study was an increase in the number of Crohn’s disease and eosinophilic gastrointestinal disorder cases. Bowel preparation with magnesium citrate was significantly increased across all ages in the present study (142/164, 86.6%). Midazolam + pentazocine was used for sedation in most cases (137/164, 83.5%). An ultrathin upper endoscope was mainly used in patients aged ≤6 years, while ultrathin colonoscopes were applied in patients aged 7–12 years. Conclusion: In the present study, appropriate changes were found in the roles and methods of diagnostic colonoscopy in pediatric patients compared to the previous study. The increasing trend of patients presenting with inflammatory bowel disease and eosinophilic gastrointestinal disorder worldwide indicates the importance of colonoscopy in infants and children.
