为了再度评价卢戈氏液内镜下食管粘膜染色对食管早期癌和表浅癌的诊断价值，对１４４例食管早期癌可疑患者进行食管粘膜染色，并对不染区多点活检送病理检查，其中１３１例为肉眼无可疑病灶者，９４例没有任何食管症状。诊断结果：食管癌７例（手术证实粘膜癌２例，粘膜下癌２例）；不典型增生１０例（轻度５例，中度３例，重度２例）；单纯上皮增生伴或不伴慢性炎症２５例；结核１例。并发现有食管症状者碘不染区出现率明显高于无食管症状者（Ｐ＜０．０５）。结论：内镜下卢戈氏液染色有助于食管早期癌、表浅癌及癌前病变的诊断，并帮助鉴别诊断
In order to reassess the diagnostic value of Lugol’s endoscopic esophageal mucosal staining for early esophageal cancer and superficial cancer, 144 esophageal early-stage cancer patients were stained for esophageal mucosa and pathological examinations were performed on multi-point biopsy in the non-stained area. Of these, 131 cases were undetectable lesions with naked eyes, and 94 cases had no esophageal symptoms. Diagnosis: 7 cases of esophageal carcinoma (2 cases of mucous carcinoma confirmed by surgery, 2 cases of submucosal carcinoma); 10 cases of dysplasia (5 mild cases, 3 moderate cases, 2 severe cases); simple epithelial hyperplasia with or without There were 25 cases of chronic inflammation and 1 case of tuberculosis. The incidence of iodine-free areas with esophageal symptoms was significantly higher than those without esophageal symptoms (P<0.05). Conclusion: Endoscopic Lugol’s staining is helpful for the diagnosis of early esophageal carcinoma, superficial carcinoma and precancerous lesions, and helps differential diagnosis
