Background. There has been a growing use of both capsule endoscopy (CE) and double balloon enteroscopy (DBE) to diagnose and treat patients with obscure gastrointestinal blood loss and suspected small bowel pathology. Aim. To compare and correlate sequential CE and DBE findings in a large series of patients at two tertiary level hospitals in Wisconsin. Methods. An IRB approved retrospective study of patients who underwent sequential CE and DBE, at two separate tertiary care academic centers from May 2007 to December 2011, was performed. Results. 116 patients were included in the study. The mean age ± SD was 66.6 ± 13.2 years. There were 56% males and 43.9% females. Measure of agreement between prior capsule and DBE findings was performed using kappa statistics, which gave kappa value of 0.396 with P < 0.001. Also contingency coefficient was calculated and was found to be 0.732 (P < 0.001). Conclusions. Our study showed good overall agreement between DBE and CE. Findings of angioectasia had maximum agreement of 69%.
背景。胶囊内镜（CE）和双气囊小肠镜（DBE）在诊断和治疗不明原因胃肠道出血及疑似小肠病变患者中的应用日益广泛。目的。比较威斯康星州两家三级医院大量患者中序贯进行的CE和DBE检查结果，并进行相关性分析。方法。对2007年5月至2011年12月在两个独立的三级医疗学术中心接受序贯CE和DBE检查的患者进行了一项经机构审查委员会批准的回顾性研究。结果。116名患者纳入研究。平均年龄±标准差为66.6±13.2岁。男性占56%，女性占43.9%。使用kappa统计量对先前胶囊内镜和DBE检查结果之间的一致性进行测量，kappa值为0.396，P<0.001。还计算了列联系数，结果为0.732（P<0.001）。结论。我们的研究表明DBE和CE之间总体一致性良好。血管扩张的检查结果一致性最高，为69%。
