摘　　要：目的　探讨如何通过放大内镜和实体显微镜观察分析大肠息肉腺管开口类型 ,从而发现早期大肠癌及癌前病变。方法　2 0 0 1年 8月～ 2 0 0 2年 2月结肠镜检查 139例大肠病变。采用内镜下黏膜染色技术 ,结合放大内镜、实体显微镜观察腺管开口分型 (pitpat tern)并与病理诊断对照。结果　139例患者中发现大肠息肉 12 4例 ,进展期癌 9例 ,LST型病变 5例。 5例LST的直径为 10～5 0mm ,其中ⅢL型 1个 ,Ⅳ型 4个。本组采用放大内镜与病理、实体显微镜诊断的符合率高。结论　大肠腺管开口对于判断肿瘤性、非肿瘤性病变以及早期大肠癌具有重要意义 。Objective To investigate the relationship between early colonic cancer and the pit patterns of abnormal colonic mucosa. Methods We examined the pit patterns of 124 polypi in 139 patients by magnifying colonoscopy and stereomicroscopy, and compared the relations between the pit patterns and pathological diagnosis of polypi. Results 5 cases of LST(laterally spreading tumor)and 9 cases of advanced cancer were found out of 124 polypi in 139 patients. 1 among these 5 cases of LST showed Ⅲ L pit pattern, and 4 showed Ⅳ pit pattern with both magnifying colonoscopy and stereomicroscopy. Magnifying colonoscopy showed high coincidence rate with stereomicroscopy. Conclusion Pit patterns are found to be very important in disguishing tumorous lesions from non-tumorous lesions, and to discover early colonic cancer. Ⅴ pit pattern indicates that the polyp is carcinomatous.
