Abstract
Objective To investigate the application value of narrow band imaging combined with magnifying endoscopy (NBI-ME) in the diagnosis of early carcinoma and precancerous lesions of gastrointestinal tract in elderly patients.Methods Eight hundred and twenty four elderly patients examed by NBI-ME were selected as the observation group and 815 patients examed by routine gastrointestinal endoscopy were selected as the control group.The detection rates of advanced carcinoma,early carcinoma,precancerous lesions of gastrointestinal tract in the two groups were observed and compared.Results The detection rates of early carcinoma,precancerous lesions of gastrointestinal tract in patients of observation group were significantly higher than those in control group (χ2=4.715,6.500.P<0.05).The sensitivities of NBI-ME examination in the diagnosis of early carcinoma,precancerous lesions of gastrointestinal tract were significantly higher than those of routine gastrointestinal endoscopy examination (χ2=5.916,10.471.P<0.05).The Youden index and the consistency coefficient (kappa) compared with pathological biopsy results were significantly higher than those of routine gastrointestinal endoscopy examination,but there were no statistically significant differences (χ2=0.985,1.031.P>0.05).Conclusion The sensitivity and detection rate of NBI-ME in the diagnosis of early carcinoma,precancerous lesions of gastrointestinal tract are higher and can be used as a effective clinical diagnostic measures.关键词
