Double-balloon enteroscopy for pediatric patients: Application and feasibility evaluation in a medical center in northern Taiwan

Abstract

Background/Purpose: The diagnostic and therapeutic benefits of double-balloon enteroscopy (DBE) in adults are established, but few data are available on pediatric patients. The aim of this study was to evaluate the clinical efficacy and safety of DBE in pediatric patients in Taiwan. Methods: From April 2005 to September 2015, DBE procedures performed for diagnosis or therapy of small-bowel disease in children less than 18 years of age at Linkou Chang Gung Memorial Hospital, Taiwan were evaluated. The clinical decision to perform DBE via the oral or anal approach was based on the patient's primary clinical presentation. Data on indications, endoscopic findings, treatment outcome, and complications associated with the procedure were collected and reviewed retrospectively. Result: In total, 20 pediatric patients underwent a total of 29 DBEs due to suspicion of small-bowel disease. Among them, nine patients were evaluated for suspected small-bowel bleeding, six for Peutz-Jeghers syndrome, two for chronic abdominal pain, two for chronic diarrhea, and one for suspected protein-losing enteropathy. After excluding the six Peutz-Jeghers syndrome patients, 9 of the 14 patients (64%) got a positive endoscopic finding and diagnosis in 8 of the 14 patients (57%). DBE resulted in a further therapeutic intervention (endoscopic or surgical) in 50% of the patients (10/20) without serious complications. Conclusion: DBE has a high diagnostic yield and leads to therapeutic interventions in pediatric patients and shows promise for assessment and treating small-intestinal diseases in children in Taiwan.
