内镜下卢戈液染色诊断早期食管癌

目的：研究内镜下卢戈液染色诊断早期食管癌的临床可行性。方法：168例患者经内镜下喷洒卢戈氏液对食管粘膜染色后观察，并取不染区组织进行病理检查。结果：168例患者中有123例食管粘膜呈不规则片状不染或着色不良，经病理检查发现食管鳞癌16例，腺癌4例，各种程度的不典型增生52例，不同程度的炎症51例。正常着色者25例，深染者14例与散在小点状着色不良者6例中病理结果为轻度慢性炎症35例，未见明显异常者10例。结论：内镜下卢戈液染色是提高食管癌及癌前病变检出率的有效方法。

Endoscopic Lugol''''s iodine staining for diagnosis of early esophageal cancer

Aim:To explore the clinical feasibility of Lugol's iodine staining for diagnosis of early esophageal cancer through endoscopy. Methods:Lugol's iodine was sprayed on the esophageal mucosa from 168 cases through endoscopy, and multiple biopsies were taken for pathology detection from unstained areas. Results:In 123 cases of unstained mucosa as irregular area revealed 16 squamous carcinomas, 4 adenocarcinomas, 52 different level dysplasias and 51 inflammations. Among the cases of 25 normal stained, 14 strong stained, 6 scattering points dystained, there were 35 slight chronic inflammations and 10 normals. Conclusion:Lugol's iodine endoscopic staining is useful for raising the diagnostic rate of early esophageal cancer and precancerous lesion.
