对位于食管癌高发区的河南省新乡地区中心医院和位于低发区的湖北汉口协和医院3年间胃镜检出的食管炎及食管癌进行对比观察。发现高发区鳞癌的检出率明显高于低发区(P<0.001),而腺癌的检出率却无明显差异(P>0.05)。高发区上、中段食管炎检出率明显高于低发区,而下段食管炎的检出率两地区无明显差异(P>0.05)。
The esophagitis and esophageal cancer detected by gastroscope were compared between the Central Hospital of Xinxiang District in Henan Province, which is a high incidence area of esophageal cancer, and the Hubei Hankou Xiehe Hospital in the low incidence area. It was found that the detection rate of squamous cell carcinoma in high-risk areas was significantly higher than that in low-risk areas (P<0.001), but there was no significant difference in the detection rate of adenocarcinoma (P>0.05). The detection rate of esophagitis in the upper and middle areas of the high-incidence area was significantly higher than that in the low-risk area, but the detection rate of the lower esophagitis was not significantly different between the two areas (P>0.05).
