目前许多资料表明结肠腺瘤可恶变导致结肠癌,而结肠癌在内镜下都可看到不同程度的出血,所以我们现将腺瘤分为出血型腺瘤(即表面有出血而导致便血),不出血型腺瘤(即表面无出血,无临床症状)。但是目前这两种类型腺瘤之间的差异还未阐明清楚,这方面资料也很少,故我们仅就腺瘤在内镜下的形态、表面积、颜色、部位及显微镜下的表面结构进行初步研究分析如下。 At present, many data show that colon adenoma can cause malignant transformation of colon cancer, and colon cancer can be seen in different degrees of bleeding under the endoscope, so we now divide adenomas into hemorrhagic adenomas (that is, the surface has bleeding caused by blood in the stool) No hemorrhagic adenoma (ie no bleeding on the surface, no clinical symptoms). However, the difference between these two types of adenomas has not yet been elucidated, and there are few data in this regard. Therefore, we will only conduct preliminary studies on the morphology, surface area, color, location, and surface structure of the adenomas under the microscope. Research and analysis are as follows.
