@entity788 @entity5 @entity660 @entity513 @entity850
BACKGROUND: The aim of this study was to evaluate the usefulness of peroral pancreatoscopy in the diagnosis of @entity660 . METHODS: Both 3.7-mm (thin) and 0.8-mm (ultra-thin) diameter fiberoptic pancreatoscopes were used in 115 cases ( @entity788 , 35; @entity513 , 20; @entity5 , 60). RESULTS: Observation rates for @entity788 , @entity513 , and @entity5 were, respectively, 63%, 80%, and 95%. Tumor vessels and @entity5 were observed when @entity788 was smaller than 2 cm but not when the @entity5 was larger than 2 cm. @entity850 without significant mucosal changes was observed in 62% of cases of @entity513 . Coarse mucosa and friability were observed more frequently in association with @entity788 than @entity513 . Granular mucosa or @entity5 could be observed in 74% of cases of @entity5 . @entity5 was observed with increasing frequency in cases of @entity5 as the degree of @entity5 increased. CONCLUSIONS: Peroral pancreatoscopy with an ultra-thin fiberscope is useful in the diagnosis of minute @entity660 . Peroral pancreatoscopy with a thin fiberscope can provide a definitive diagnosis of @entity5 including the degree of @entity5 .
