The Diagnostic Value of Double-Balloon Enteroscopy in Children with Small Bowel Disease: Report of 31 Cases
BACKGROUND AND OBJECTIVE: Before the introduction of double-balloon enteroscopy (DBE), it was impossible to visualize the entire small bowel. Its diagnostic yield has been assessed in adults, but not yet in children. The present retrospective study evaluated the diagnostic usefulness and safety of DBE in children with suspected small bowel disease.METHODS: Between June 2003 and June 2007, 31 patients (19 boys and 12 girls, age range three to 14 years) with suspected small bowel disease underwent DBE after receiving negative evaluations using other diagnostic modalities.RESULTS: There were no severe complications. In two patients, the entire small bowel was viewed using oral and anal approaches, and for the remaining 29 patients, only one approach was used. The sites of disease in were identified in 25 of 31 cases (80.65%). The bleeding source was found in 21 of 27 patients with obscure gastrointestinal bleeding (diagnostic rate of 77.78%). Different diseases were identified in four children with chronic diarrhea.CONCLUSION: DBE is a safe and effective method to diagnose patients with suspected small bowel disorders.
