结肠镜检查是当前最好的确诊方法,不仅能发现早期病变,还能取活检做病理检查,漏诊率低,价格便宜。不足之处是肿瘤造成肠管狭窄时不能全面观察,定位有时不准,与操作者水平有密切关系。不少人对此检查顾虑重重,实无必要。 Colonoscopy is currently the best diagnostic method. It can not only detect early lesions, but also take biopsy for pathological examination. The rate of missed diagnosis is low and the price is cheap. The inadequacy of the tumor is that it cannot be fully observed when the tumor causes intestinal stenosis, and the positioning is sometimes inaccurate, which is closely related to the operator’s level. Many people are worried about this inspection and it is really unnecessary.
