Relationship between age and site of XXXX based on colonoscopy findings.

@entity1 @entity652 @entity29 @entity14 @entity2513 @entity694 @entity420
BACKGROUND: @entity14 occurs more frequently in older @entity1 . Because the population of aged @entity1 is increasing, a better understanding of the characteristics of @entity14 with respect to age would be useful. The purpose of this study was to determine whether there is any relationship between the site of @entity2513 and @entity420 in the colon and age. METHODS: Colonoscopy was performed (September 1995 to December 1998) on 2942 consecutive @entity1 (1907 @entity1 , 1035 @entity1 ; mean age 61 years, range 11 to 95 years) with no history of @entity2513 , @entity420 , or @entity29 . The occurrence of @entity14 , histologically proven as @entity652 or @entity420 , was analyzed for a possible association between site in the colon and @entity1 age. RESULTS: @entity420 was found in 191 @entity1 (196 lesions). The proportion of @entity1 with right-sided @entity694 increased with @entity1 age: < 50 years, 15% (2/13); 50 to 59 years, 21% (8/39); 60 to 69 years, 32% (18/57); 70 to 79 years, 42% (25/49); > or =80 years, 57% (16/28). The proportion of @entity1 with right-sided @entity652 did not significantly differ among age groups: < 50 years, 40% (98/246); 50 to 59 years, 41% (280/678); 60 to 69 years, 46% (459/1001); 70 to 79 years, 53% (270/508); and > or =80 years, 57% (87/152). CONCLUSION: The frequency of right-sided @entity694 increases with @entity1 age. Hence, colonoscopy may be indicated in the elderly for @entity14 screening. Over half of @entity694 may be missed if sigmoidoscopy alone is used for screening.
