本文对214例(其中仅12例无症状)做食管拉网检查者先行舌象观察,最后确诊为食管癌者151例,其中青紫舌105例,非青紫舌46例,差异显著(p<0.01)。非食管癌者63例,其中青紫舌31例,非青紫舌32例,差异不显著。作者认为用舌诊做食管癌普查粗筛不适宜,因将有1/3患者漏诊。作者对青紫舌的机理简要叙述。 In this study, 214 patients (only 12 of them were asymptomatic) who underwent esophageal pull-net examination were observed first. The final diagnosis was 151 cases of esophageal cancer, including 105 cases of cyanotic tongue and 46 cases of non-cyanotic tongue, with significant differences (p<0.01). ). There were 63 cases of non-esophageal cancer, including 31 cases of cyanotic tongue and 32 cases of non-cyanotic tongue. The difference was not significant. The author believes that the use of tongue diagnosis for esophageal cancer screening is inappropriate, as 1/3 of patients will miss the diagnosis. The author briefly describes the mechanism of cyanosis.
