Reduction or elimination of catharsis with fecal tagging enhances the tolerability of CT colonography (CTC) and may increase compliance with colorectal cancer (CRC) screening recommendations. We systematically reviewed studies that prospectively evaluated performance and patient satisfaction with decreased-purgation CTC and with optical colonoscopy.
The nine studies reviewed showed moderate-to-good performance for decreased-purgation CTC; however, data are limited, and study design and data presentation are inconsistent. Further study of decreased-purgation CTC and standardization of terminology are needed.
减少或消除粪便标记的催泻作用可提高 CT 结肠成像（CTC）的耐受性，并可能提高结直肠癌（CRC）筛查建议的依从性。我们系统地回顾了前瞻性评估低清肠 CTC 和光学结肠镜检查的性能和患者满意度的研究。
所审查的九项研究表明，低清肠 CTC 的性能为中等至良好；然而，数据有限，且研究设计和数据呈现不一致。需要进一步研究低清肠 CTC 并使术语标准化。
