结直肠癌作为发病率位居第三的癌症,已成为一个严重威胁人类健康的全球性问题。随机临床试验结果显示,高效的筛查方法能同时降低结直肠癌的发病率和死亡率,并为直肠癌的鉴别诊断提供强有力的参考依据。许多研究者认为,结肠镜是筛查结直肠癌的较优的检查方法。不过,目前结直肠癌的筛检率仍相对较低,亟待提高。结肠镜检查也可广泛应用于结直肠
As the third highest incidence of cancer, colorectal cancer has become a global problem that poses a serious threat to human health. Randomized clinical trial results show that an efficient screening method can reduce the morbidity and mortality of colorectal cancer at the same time and provide a powerful reference for the differential diagnosis of rectal cancer. Many researchers believe that colonoscopy is a better screening method for screening colorectal cancer. However, the screening rate of colorectal cancer is still relatively low and needs to be improved urgently. Colonoscopy can also be widely used in colorectal
