Gross versus microscopic pancolitis and the occurrence of XXXX in @entity31 .

OBJECTIVE: The gross extent of @entity31 ( @entity31 ) is a recognized risk factor for the development of @entity1960 and @entity14 ( @entity14 ). The risk of @entity5 associated with the microscopic extent of @entity1960 is unknown. The aim of this study was to describe the gross and microscopic extent of @entity1960 in @entity1 with @entity31 -related @entity1141 / @entity14 . METHODS: All @entity1 who underwent colectomy at our institution between 1992-2001 with @entity1960 / @entity14 were identified. Histological sections from each colectomy specimen were reviewed for the microscopic extent of @entity1960 and the location of all lesions with @entity1141 / @entity14 . RESULTS: Thirty-six @entity1 with @entity1960 / @entity14 were identified of whom 30 had slides available for review. Gross pancolitis was identified in 19 @entity1 , though microscopic pancolitis was evident in all 30 @entity1 . Among the 11 @entity1 with only distal gross @entity1960 , 4/15 @entity1313 were proximal to the area of gross involvement. CONCLUSIONS: @entity31 -related @entity5 can occur in areas of the colon not grossly involved with @entity1960 , though it did not occur in any @entity1 without microscopic pancolitis. To devise rational @entity5 surveillance guidelines, further studies are needed to determine the risk of @entity1960 in @entity1 with microscopic pancolitis but limited gross disease.
