以往我们是按常规方法制作食管癌和贲门癌组织切片,即将受检物纵切成若干条,再横切成若干快、经脱水、石蜡包埋切片。按这种方法,一条食管标本要取20多块组织。这不仅工作量大,制作时间长。而且因组织块小,不能进行全面的形态学观察。尤其是早期癌病变的范围小,或为多中心性生长,小块组织切片往往破坏了病变与周围组织间相互关系,有时甚至漏切了主要病变,从 In the past, we used routine methods to create sections of esophageal and cardiac cancers. The samples were cut into several pieces and cut into several pieces of fast, dehydrated, and paraffin-embedded sections. According to this method, an esophageal specimen should take more than 20 tissues. This is not only a heavy workload, but also a long production time. And because of the small size of the tissue, comprehensive morphological observations are not possible. In particular, the scope of early cancer lesions is small, or multicentric growth, small tissue sections often destroy the relationship between the lesion and the surrounding tissue, and sometimes even miss the main lesion, from
