Degree of concordance between single balloon enteroscopy and capsule endoscopy for obscure gastrointestinal bleeding after an initial positive capsule endoscopy finding

Introduction:In patients with obscure gastrointestinal bleeding (OBGIB) capsule endoscopy (CE) is the initial diagnostic procedure of choice. Often patients undergo single balloon enteroscopy (SBE) with both diagnostic and therapeutic intention after CE. Although SBE offers a therapeutic benefit, long procedure times, complexity, and invasiveness are drawbacks. We aimed to evaluate the diagnostic correlation between these two modalities after an initial positive CE finding.Methods:We performed a retrospective review of 418 patients who underwent CE at our institution from January 2010 to May 2014. A total of 95 patients were analyzed after selecting patients that underwent SBE originally after a positive CE result for the evaluation for OGIB. Agreement beyond chance was evaluated using the κ coefficient. A p value less than 5% was considered statistically significant.Results:The mean age of our population was 65.8 ± 12.2 and it was female predominant: 57/95 (60%). The most frequent positive findings were ...
