早期诊断大肠癌在我国是一个重要课题,应用放大大肠镜试图早期发现大肠癌及其他病变已有一些报道,但从病理学角度较系统的研究并不多见。我们在研究胃粘膜炎症性及细小癌性病变的基础上,应用立体显微镜并用色素法,观察大肠癌,腺瘤及慢性炎症粘膜面的亚肉眼形态特征,并与组织学进行对比研究,以探索上述各种病变的鉴别点,为放大大肠镜的临床实践提供病理形态学基础。 Early diagnosis of colorectal cancer is an important issue in our country. There have been some reports on the use of magnifying colonoscopy in early detection of colorectal cancer and other lesions. However, systematic studies have been rare in terms of pathology. Based on the study of inflammatory and small cancerous lesions of the gastric mucosa, we used stereomicroscope and pigmentation methods to observe the submacromorphic features of colorectal cancer, adenoma, and chronic inflammatory mucosal surface, and compared it with histology to explore The discrimination points of the above-mentioned various lesions provide a pathological morphological basis for enlarging the clinical practice of colonoscopy.
