近年来,由于胃肠纤维内窥镜的应用,使胃肠疾患的诊断水平有了较大的提高。但是,对一些微小的恶性病变的病例,单靠内窥镜直视下活检,即使有经验的医生漏诊也在所难免。文献报告在内窥镜下配合染料着色法可使胃癌诊断正确率由83％上升至98.1％。最近,我们开展了这一工作,先后染色了40例,现报告如下: 资料与方法本组40例中,男性31例,女性9例,年龄从35至71岁。一、染色方法: 1,撤布法:于检查前一天晚上口服缓冲液(每1000毫升蒸馏水内含
In recent years, due to the application of gastrointestinal fiber endoscopes, the diagnostic level of gastrointestinal disorders has been greatly improved. However, in the case of some minor malignant lesions, biopsy under the direct view of the endoscope alone is inevitable even if an experienced doctor missed the diagnosis. The literature reports that the diagnostic accuracy of gastric cancer can be increased from 83% to 98.1% with endoscopic dye staining. Recently, we have carried out this work and have stained 40 cases. The report is as follows: Materials and Methods In this group of 40 cases, 31 were males and 9 were females, aged from 35 to 71 years. First, the dyeing method: 1, withdrawal method: on the night before the oral administration of oral buffer (per 1000 milliliters of distilled water containing
