Abstract

Background/aims: Colorectal cancer prevention relies on surveillance colonoscopy, with the adenoma detection rate as a key factor in examination quality. Linked color imaging (LCI) enhances lesion contrast and improves the examination performance. This systematic review and meta-analysis aimed to evaluate the effect of LCI on adenoma detection rate in adults who underwent colonoscopy.

Methods: We searched the Medline, PubMed, BIREME, LILACS, and Scientific Electronic Library Online databases for randomized controlled trials comparing the use of LCI versus white light (WL), published up to March 2023. The outcomes included lesion characteristics, number of adenomas per patient, and the additional polyp detection rate.

Results: Sixteen studies were included in the analysis, which showed that LCI was more accurate than WL in detecting adenomas, with an increased number of adenomas detected per patient. Although LCI performed well in terms of lesion size, morphology, and location, the subgroup analyses did not reveal any statistically significant differences between LCI and WL. The addition of LCI did not result in significant improvements in the detection of serrated lesions, and there were no differences in the withdrawal time between groups.

Conclusions: LCI has been shown to be effective in detecting colonic lesions, improving the number of adenomas detected per patient and improving polyp detection rate without negatively affecting other quality criteria in colonoscopy.

联动彩色成像对结肠镜检查腺瘤检出率的影响:系统回顾和荟萃分析。
背景/目的:大肠癌的预防主要依靠结肠镜检查,而腺瘤的检出率是影响检查质量的关键因素。联动彩色成像(LCI)可增强病灶对比度,提高检查效果。本系统综述和荟萃分析旨在评估 LCI 对成人结肠镜腺瘤检出率的影响:我们在 Medline、PubMed、BIREME、LILACS 和科学电子图书馆在线数据库中检索了截至 2023 年 3 月发表的比较 LCI 与白光 (WL) 使用情况的随机对照试验。结果包括病变特征、每位患者的腺瘤数量以及额外的息肉检出率:结果:16 项研究被纳入分析,结果显示,LCI 在检测腺瘤方面比 WL 更准确,每位患者检测到的腺瘤数量也有所增加。虽然LCI在病变大小、形态和位置方面表现良好,但亚组分析并未发现LCI与WL之间存在任何统计学意义上的显著差异。加入 LCI 后,锯齿状病变的检出率并没有明显提高,而且各组间的停药时间也没有差异:LCI在检测结肠病变、提高每位患者检出腺瘤的数量和提高息肉检出率方面效果显著,且不会对结肠镜检查的其他质量标准产生负面影响。
