Predictability of capsule endoscopy referred to a tertiary care center for double-balloon enteroscopy

Academic Article

Abstract

  • Objectives Patients with obscure gastrointestinal bleeding with 'positive' findings on video capsule endoscopy (VCE) by gastroenterologists practicing in the community are often referred to tertiary care centers for double-balloon enteroscopy (DBE). Our study explores the degree of concordance between these two procedures performed in two different clinical settings. Methods Concordance between the procedures was estimated using a κ-coefficient. Results A total of 73 patients with obscure gastrointestinal bleeding were referred to our center for DBE after undergoing VCE elsewhere. Ten of these patients (10/73 or 13.7%) had been found to have bleeding in the small bowel on VCE without any concrete diagnosis. DBE revealed the source of bleeding in 17 of the 22 patients (77.3%) with normal VCE. The referral diagnosis was correct in 31 cases (31/73 or 42.5%). The κ-coefficient for VCE and DBE for the 63 patients was 0.28, suggesting poor agreement between the two procedures. However, most patients with a referral diagnosis of vascular pathology were confirmed to have vascular disease on DBE (19/23 or 82.6%). Conclusion Our study shows that there is a poor concordance between capsule endoscopy performed in the community and confirmatory DBE performed at our tertiary care center.
