摘　　要：目的:探讨蓝激光成像放大胃镜(Blue laser imaging magnifying gastroscopy,M-BLI)联合靛胭脂染色鉴别早期胃癌的价值。方法:选取2022年1月至2022年12月医院收治的60例疑似早期胃癌患者作为研究对象,均进行普通白光成像(White light imaging,WLI)检查、M-BLI联合靛胭脂染色检查,以病理检查结果为金标准,分析WLI、M-BLI联合靛胭脂染色对早期胃癌的诊断效能。结果:M-BLI联合靛胭脂染色检查图像质量评分均高于WLI检查(P<0.05)。病理学检查显示,60例疑似早期胃癌患者中,胃癌患者20例,癌前病变患者40例;M-BLI联合靛胭脂染色检查显示,胃癌患者21例,癌前病变患者39例,与病理学检查的Kappa值为0.889;WLI检查显示,胃癌患者20例,癌前病变患者40例,与病理学检查的Kappa值为0.550。M-BLI联合靛胭脂染色诊断早期胃癌的准确度、敏感度分别为95.00%(57/60)、95.00%(19/20)均高于WLI的80.00%(48/60)、70.00%(14/20)(P<0.05)。结论:M-BLI联合靛胭脂染色能获得更清晰的图像,对早期胃癌具有较高的鉴别效能。Objective:To explore the value of blue laser imaging magnifying gastroscopy(M-BLI)combined with indigo carmine staining in distinguishing early gastric cancer.Method:Sixty patients with suspected early gastric cancer were selected from the hospital from January 2022 to December 2022,all of whom underwent routine white light imaging(WLI)and M-BLI combined with indigo carmine staining.The pathological examination results were used as the gold standard to analyze the diagnostic efficacy of WLI,M-BLI combined with indigo carmine staining for early gastric cancer.Result:The image quality scores of M-BLI combined with indigo carmine staining were higher than those of WLI(P<0.05).Pathological examination showed that among 60 suspected early gastric cancer patients,20 were gastric cancer patients and 40 were precancerous lesions;M-BLI combined with indigo carmine staining showed that there were 21 patients with gastric cancer and 39 patients with precancerous lesions,with a Kappa value of 0.889 compared to pathological examination;WLI examination showed that there were 20 patients with gastric cancer and 40 patients with precancerous lesions,with a Kappa value of 0.550 compared to pathological examination.The accuracy and sensitivity of M-BLI combined with indigo carmine staining in diagnosing early gastric cancer were 95.00%(57/60)and 95.00%(19/20),respectively,which were higher than the 80.00%(48/60)and 70.00%(14/20)of WLI(P<0.05).Conclusion:The combination of M-BLI and indigo carmine staining can obtain clearer images and has high discriminatory power for early gastric cancer.
