Surveillance for @entity694 in XXXX .

@entity1 @entity227 @entity5 @entity31 @entity189 @entity1893 @entity694 @entity1141
To evaluate the efficacy of surveillance colonoscopy with biopsy for the detection of @entity1893 ( @entity1893 ) or @entity694 in @entity1 with chronic @entity31 , we undertook a retrospective review of 248 @entity1 who underwent 370 examinations (mean duration of disease 12 yr). High-grade @entity1141 or @entity189 was found in 24 examinations in 16 @entity1 , with a mean duration of disease of 16 yr. There were 15 @entity1 with @entity1893 . Nine @entity1 had @entity1893 alone, 6 had @entity1893 and @entity189 , and 1 had @entity189 without @entity1893 . The overall incidence of @entity1893 was 6%. @entity1141 -associated lesions or mass were the most consistent indicators of @entity189 , the combination being present in four instances. Of the 7 @entity1 with @entity5 , 6 were recognized by colonoscopy, and 1 @entity1 with negative @entity227 was discovered using surveillance biopsies. The conclusions of this study are that @entity1141 is a reliable histopathologic marker and correlates with the presence of @entity5 in chronic @entity31 ; the absence of @entity1141 correlates with the absence of @entity5 . The presence of @entity1141 -associated lesions or mass with @entity1893 is the strongest indication for operation. This study supports the use of surveillance colonoscopy in managing high-risk @entity31 @entity1 .
