本文报告３６例胃癌患者普通胃镜和煌蓝色素内镜检查以及活检的结果。其中７例为早期胃癌，早期胃癌的检出率为１９．４％。普通胃镜仅发现１例早期癌，煌蓝色素内镜发现７例，差异有显著意义（Ｐ＜０．０５）。此外煌蓝色素内镜提高胃癌活检阳性率达９７．４％。也明显高于普通胃镜的活检阳性率（Ｐ＜０．０１）。作者认为在胃癌前病变的随访中应提倡使用煌蓝色素内镜。
This article reports the results of common gastroscopy and bluing blue endoscopy and biopsy in 36 patients with gastric cancer. Among them, 7 cases were early gastric cancer, and the detection rate of early gastric cancer was 19.4%. Only one case of early cancer was detected by ordinary gastroscopy, and 7 cases were found by endoscopic blue staining. The difference was significant (P<0.05). In addition, the blue pigment endoscopy increased the positive rate of gastric cancer biopsy by 97.4%. It was also significantly higher than the normal biopsy positive rate (P<0.01). The authors believe that the use of bluish-blue endoscopy should be advocated in the follow-up of precancerous lesions.
