摘要
为着重研究大肠小的扁平腺瘤和非腺瘤性的早癌,本组146例(168枚)大肠小的扁平隆起病变经病理活检进行内镜下形态和组织学对照研究。结果证实粘膜慢性炎19例,炎性息肉63例(72枚)、增生性息肉34例(42枚),小的扁平腺瘤27例(32枚)不含腺瘤成份的早癌3例。研究结果表明对大肠腺瘤的概念必须重新认识。在肠镜检查过程中,仅仅注意息肉样病变是不够的,还要观察小的扁平和凹陷性病变,才能提高我们对腺瘤和早期癌的诊断水平。
Colonoscopy has been applied extensively,it supplies beneficial condition for the research of colorectal small nonpolypoid lesion.From Jan.1987 to Dec.1995,146 cases with colorectal small flat or depressed lesios were found by colonoscopy,which were accomplished with biopsy.The lesions were contrasted in the research of endoscopic morphosis and clinic pathologic morphology.Among 146 lesions,19 cases with mucositis,63 cases with inflammatory polyps,34 cases with the hyperplasia polyps 25 cases with the small flat adenoma,2 cases with the depressed adenoma,and 3 cases with nonadenomatoid earaly cancer (de novo cancer)were confirmed.All lesions of 27 small flat and depressed adenomas,except one case with villous adenoma,were tubular adenomas.Two of 27 lesions were confirmed with the intramucosal adenoma.Three cases with de novo cancer,one type IIa and two type IIc were confirmed.One of three lesions confirmed by biopsy underwent radical operation,but the carcinoma couldn’t be found in the specimen of surgical excision which was quite unusual carcinoma in situ or one point cancer.The results of our research showed that not all adenomas are raised in the large bowel.For this reason,it should be observed not only polypoid lesion,but also small flat and depressed lesion with colonscopy.It is profitable for the diagnosis of small flat adenoma and type Ⅱc early cancer.
