A paper reports the results of a retrospective study that was designed to evaluate the potential role of video capsule endoscopy (VCE) in elucidating the cause of bleeding in patients with obscure gastrointestinal bleeding (OGIB) for whom CT enterography was negative. The authors highlight the limitations of dual-phase CT enterography for the detection of flat lesions of the small bowel such as ulcers, angiodysplasias or arteriovenous malformations, and confirm the superiority of VCE for the detection of this category of lesions. This commentary discusses some of the issues raised.
• Video capsule endoscopy surpasses CT enterography in detecting flat small bowel lesions. • Retrospective VCE and CT enterography findings in obscure bleeding need further evaluation. • A fair and unbiased comparison of the two investigations is still needed.
一篇论文报告了一项回顾性研究的结果，该研究旨在评估视频胶囊内镜（VCE）在阐明 CT 肠造影术阴性的不明原因胃肠道出血（OGIB）患者出血原因方面的潜在作用。作者强调了双相 CT 肠造影术检测小肠平坦病变（如溃疡、血管扩张或动静脉畸形）的局限性，并证实 VCE 在检测此类病变方面具有优越性。本评论讨论了其中的一些问题。
视频胶囊内镜在检测小肠平坦病变方面优于 CT 肠造影术。
对隐匿性出血的 VCE 和 CT 肠造影术的回顾性研究结果需要进一步评估。
仍需要对这两种检查进行公正、无偏见的比较。
