ルゴール染色の診断的価値―食道非癌病変を対象にして

Lugol Staining in Diagnosing Benign Esophageal Lesions

要旨　ルゴール染色は食道内視鏡検査で欠くことのできないものとなっており，癌のみならず良性病変の診断にも有用である．良悪性の鑑別や良性びらん潰瘍の病期の診断も可能であり，積極的に適応していくべきと考えている．異型上皮，食道潰瘍，逆流性食道炎，白斑，hyperkeratosis，乳頭腫，ポリープ，平滑筋腫，異所性胃粘膜，Barrett上皮などについてルゴール染色の実際を呈示し，解説した．

　Lugol staining in the esophagoscopic examination is extremely useful for diagnosing not only esophageal carcinoma but also benign lesions.

　This method is indicated to differentiate malignant lesions from benign ones, and particularly to determine the healing stage of benign erosion or ulcer. The lugol staining should be used more frequently in the routine esophagoscopy.

　Application of this method is described in such lesions as dysplasia, ulcer, reflux esophagitis, leucoplakia, hyperkeratosis, papilloma, polyp, leiomyoma, ectopic gastric mucosa, and Barrett esophagus.
