RESUMO
AIM: Although flexible sigmoidoscopy (FS) is utilized in children for the diagnosis of pediatric gastrointestinal conditions, such as inflammatory bowel disease and juvenile polyp disorders, the diagnostic yield of FS in pediatric patients is unknown. MATERIALS AND METHODS: We retrospectively reviewed FS cases in children under 18 years of age over a five-year period at our institution. Indications for the procedure, endoscopic visual findings, histologic findings, final diagnosis, and any management changes based on FS findings were included. RESULTS: A total of 354 cases were included in the analysis for which 40 cases (11.3%) had abnormal visual findings, 48 cases (13.6%) had abnormal histologic findings, and 13 cases (3.7%) had both abnormal endoscopic visual and histologic findings. Of the 88 cases with abnormal visual and/or histologic abnormalities, only the results of 34 of these FS cases led to a change in management based on endoscopic findings (9.6%). Most patients with a non-diagnostic FS had a final diagnosis of functional abdominal pain; most patients with a diagnostic FS had a final diagnosis of colitis, not otherwise specified. CONCLUSION: Our findings suggest that FS is not a helpful diagnostic endoscopic intervention in pediatric patients, especially in children with reassuring history and physical exam findings.
