Usefulness of magnifying endoscopy in the diagnosis of early XXXX .

@entity1 @entity189 @entity5 @entity356
BACKGROUND AND STUDY AIMS: We investigated the characteristic findings of early @entity356 revealed by magnifying endoscopy, and clarified their relationship with histopathological features. @entity1 AND METHODS: A total of 74 @entity1 with early @entity356 underwent magnifying endoscopy ( x 80) between March 2000 and December 2001. The endoscopic findings demonstrated 11 @entity189 and 63 depressed-type, and histological examination showed 56 differentiated @entity189 . The histopathological results were compared with findings from magnifying endoscopy regarding minute surface structure and microvessels. RESULTS: We were able to roughly classify the minute surface structure of early @entity356 as shown by magnifying endoscopy into three patterns, as follows: (i). a small regular pattern of sulci and ridges; (ii). an irregular pattern of sulci and ridges; and (iii). a lack of visible structure. Abnormal microvessels observed in @entity5 were classified according to two patterns: irregular minute vessels and variation of vessel caliber. The small regular pattern of sulci and ridges was significantly more frequently observed in differentiated @entity189 (30/56, 53.6 %) than in undifferentiated @entity189 (2/18, 11.1 %). Lack of visible structure and irregular minute vessels were significantly more frequently observed in undifferentiated @entity189 (44.4 % and 77.7 %) than in differentiated @entity189 (5.4 % and 51.8 %). CONCLUSION: The minute surface structure and microvessels observed by magnifying endoscopy were related to histopathological findings. Magnifying endoscopy is valuable for predicting the histological nature in the diagnosis of early @entity356 .
