Abstract
[Objective] To explore the diagnostic value and the safety of capsule endoscopy (CE) in patients with obscure gastrointestinal bleeding (OGIB). [Methods] A total of 960 patients with OG1B who were checked with CE between 2002 and 2009,including 906 cases reported in the domestic literature and 54 checked in our hospital, were reviewed retrospectively. Another 685 OGIB patients who checked with double balloon endoscopy (DBE) were used as control. [Results] The overall diagnostic yield for CE and DBE group were significant differences (respectively 72.1%, 83.1%, P <0.05), and DBE was superior to CE in the diagnostic yield of intestinal diverticulum and tumor, and there were no significant difference in diagnostic yield of vascular lesions, inflammatory lesions, polyps, Crohn's disease between CE and DBE group (P >0.05). CE and DBE group were both well tolerated, there were no significant difference in constituent ratio of adverse events between CE group and DBE group (4.3% vs 4.1%, x2= 0.855, P>0.05). [Conclusions] Despite DBE is superior to CE in the diagnostic yield of OGIB, but CE is still higher diagnostic value, and simple, no pain, better patient compliance and safety.关键词
