经纤维结肠镜检查1268例,诊断出大肠癌108例,其中检出早期大肠癌15例,占同期大肠癌13.8％。在15例早期癌中,2例伴同步癌,5例伴同步息肉,10例早期癌镜检前行钡剂灌肠检查仅5例得到诊断(50％)。本文讨论指出:纤维结肠镜加活检对早期大肠癌的诊断率明显高于钡剂灌肠,腺瘤样息肉与早期大肠癌有密切关系;鉴于大肠癌常并发同步癌和同步息肉,强调结肠镜应尽可能做全结肠观察。 After 1268 cases were diagnosed by colonoscopy, 108 cases of colorectal cancer were diagnosed. Among them, 15 cases were detected as early colorectal cancer, accounting for 13.8% of colorectal cancer in the same period. In 15 cases of early cancer, 2 cases had synchronous cancer, 5 cases had synchronous polyps, and 10 cases of barium enema before early cancer examination were diagnosed (50%). This article discusses that: fiber colonoscopy and biopsy for early colorectal cancer diagnosis rate was significantly higher than barium enema, adenomatous polyp and early colorectal cancer are closely related; given that colorectal cancer is often complicated by synchronous cancer and synchronous polyps, emphasizing colonoscopy should be Do a full colon observation as much as possible.
