虽然一般公认结肠直肠癌起源于腺瘤性息肉,但对腺瘤性息肉发生之前是否就有粘膜组织学变化则存在不同看法。作者回顾分析了用内窥镜切除的984例结肠息肉,其中708例是腺瘤性息肉,其余为非腺瘤性息肉。就粘膜而言,除腺瘤性粘膜外,还有3型粘 Although it is generally recognized that colorectal cancer originates from adenomatous polyps, there are different opinions on whether there is mucosal histological change before adenomatous polyps occur.

In the case of mucous membranes, there are 3 types of adhesions, in addition to adenomas.
