Summary
Double-balloon enteroscopy (DBE) offers superior small intestine exploration compared to push enteroscopy (PE). Antegrade DBE provides a higher diagnostic yield for small-bowel pathology, especially in non-bleeding patients without duodenal issues.
Area of Science:
- Gastroenterology
- Endoscopy
- Diagnostic Procedures
Background:
- Double-balloon enteroscopy (DBE) is a novel diagnostic procedure for small-bowel pathology.
- Push enteroscopy (PE) is an alternative method for examining the small intestine.
Purpose of the Study:
- To compare the performance and diagnostic value of antegrade DBE with PE.
- Evaluate the effectiveness of enteroscopic methods in diagnosing small-bowel conditions.
Main Methods:
- Retrospective review of endoscopic and histologic findings in 118 patients (1980-2004).
- Comparison of maximal insertion length and diagnostic yield between PE and antegrade DBE.
- Stratification of diagnostic yield by indication and duodenal pathology.
Main Results:
- Antegrade DBE achieved significantly greater insertion length (median 92 cm) than PE (median 22 cm).
- Diagnostic yield was similar in bleeding patients (40% DBE vs. 36% PE).
- Antegrade DBE showed a higher diagnostic yield in non-bleeding patients without duodenal pathology (79% vs. 31%).
Conclusions:
- Antegrade DBE is superior to PE for small intestine exploration.
- Antegrade DBE offers a better diagnostic yield for small-intestinal pathology.
