利用２％复方碘溶液（卢戈氏液）对１２０例行胃镜检查的患者进行了食管粘膜碘染色。其中１００例为肉眼观察可疑粘膜病变者，２０例为食管癌术前病例。在１００例可疑粘膜病变中，对碘呈不规则染色者８２例。经病理检查：早癌２例（经手术证实），不同程度的不典型增生２０例，不同程度炎症５３例，７例经病理检查未发现显著病变，病变检出率为９１％（７５／８２）。对２０例食管癌患者术前胃镜下碘染对病变范围进行墨汁标记，术后残端癌发生率为０。 Esophageal mucosal iodine staining was performed in 120 patients undergoing gastroscopy using a 2% compound iodine solution (Lugol’s solution). One hundred cases of macroscopic observation of suspected mucosal lesions, 20 cases of preoperative esophageal cancer cases. In 100 cases of suspected mucosal lesions, irregular staining of iodine in 82 cases. Pathological examination: early cancer in 2 cases (confirmed by surgery), varying degrees of dysplasia in 20 cases, varying degrees of inflammation in 53 cases, 7 cases of pathological examination found no significant lesions, the detection rate was 91% (75/82 ). Twenty patients with esophageal cancer underwent endoscopic gastroscopic iodine stain on the lesion range. The incidence of stump cancer was 0 after operation.
