多発小隆起型食道炎の2例

Two Cases of Small Protruded Type of Refiux Esophagitis

　食道炎の成因として種々のものがあげられているが，そのなかでも逆流性食道炎が，日常もっとも普遍的のものとして考えられている．逆流性食道炎の診断基準について，われわれは主に内視鏡所見から検討しているが，今回そのなかの隆起・肥厚型に入る，多発小隆起型食道炎ともいう2例を経験したので，X線・内視鏡所見を中心に報告する．

　A report has been made of two cases of reflux esophagitis in which multiple small protrusions were seen almost over the entire length of the esophagus. From our past experience we have classified endoscopic findings of this disease into three varieties: the Reddened Type (type A); the Erosive Type (type B); and Hypertrophic, Multiple Small Protrusion Type (type C). In type A, only reddening of the esophageal mucosa is seen. Type B shows erosive changes of the mucosa, and in type C the esophageal mucosa is dotted widely with small protrusions or leukoplakia-like elevations, and is unassociated with erosions. Hypertrophy and coarseness of the mucosa are seen extensively. As compared with type B or A, type C is of rare occurrence, accounting for only one per cent of all our experienced cases.

　Comparison of biopsy findings of each type with one another shows that both type A and B represent acute or subacute changes of the esophageal mucosa, while type C as seen in the present two cases exhibits subacute and chronic changes.
