Objectives: Capsule endoscopy (CE) has revolutionized diagnostic evaluation of patients with obscure gastrointestinal bleeding (OGB). The aim of our study was to evaluate diagnostic performance of CE in patients with OGB at our center. Methods: This retrospective study reviewed the medical records of 60 consecutive patients who had undergone capsule endoscopy because of OGB at the Hospital Pablo Tobon Uribe between September 2009 and September 2011. CE findings were interpreted according to degree of clinical relevance for definitive diagnosis: normal (P0), not very relevant (P1) and highly relevant (P2). Results: The diagnostic performance of CE for patients with OGB was 57%. No significant difference was found among patients with obvious and hidden relevant lesions (P2) OGB (63% vs. 52%, p: 0.49). 26% of relevant lesions (P2) found by EC could have been found with upper endoscopy (17%) or total colonoscopy (9%). Of the P2 lesions found, 47% were vascular, 44% were neoplastic and 9% were inflammatory. Patients with P2 lesions were older than those with P1 and P0 lesions (p: 0.05). Conclusion: The diagnostic performance of CE for OGB in our series is similar to that reported in international publications. The most frequently found P2 lesions were vascular lesions.
