目的探讨内镜下Lugol液染色对早期食管癌及非典型增生的诊断价值。方法112例患者经内镜下将Lugol液喷洒在可疑食管黏膜上,在不着色或淡染区进行病理检查。结果112例患者中有102例呈阳性,其中早期食管癌5例,进展期食管癌2例,均呈完全不着色像;不典型增生56例,呈不同程度的淡染或不染色像,其中重度不典型增生8例,均呈不染色像;慢性炎症39例,呈不同程度的浅染色像。结论内镜下Lugol液染色对诊断早期食管癌及非典型增生有重要价值。
Objective To investigate the diagnostic value of endoscopic Lugol staining for early esophageal cancer and atypical hyperplasia. Methods One hundred and twelve patients underwent endoscopy to spray the Lugol solution on suspicious esophageal mucosa and pathological examination in the non-staining or light-stained area. Results Of the 112 patients, 102 were positive, including 5 cases of early esophageal cancer and 2 cases of advanced esophageal cancer, all showed no coloration; atypical hyperplasia 56 cases showed varying degrees of light or non-staining, of which Severe dysplasia in 8 cases, were non-staining; chronic inflammation in 39 cases, showed varying degrees of light staining. Conclusion Lugol staining by endoscopy has important value in the diagnosis of early esophageal cancer and atypical hyperplasia.
