The morphologic features of 307 @entity2513 among 159 @entity1 are reviewed. Most @entity652 (66.4%) were located in the sigmoid colon and the rectum, and the percentage decreased proximally to the right colon. The 307 @entity652 comprised 244 (79.5%) tubular, 41 (13.3%) tubulovillous, and 22 (7.2%) @entity5493 . The @entity5115 was graded as mild in 260 (84.7%) @entity652 , moderate in 33 (10.7%), and severe in 14 (4.6%). The percentage of severe @entity1141 was greater in @entity5493 than in tubular @entity652 (p less than 0.05) and correlated with the increasing size (greater than 5 mm) of the @entity652 (p less than 0.01). The risk of @entity652 could be evaluated among 56 @entity1 , 34 @entity1 and 22 @entity1 with a history of removed @entity652 (s). Fourteen of 56 @entity1 (25%) with 6:1 male to female ratio developed 18 new @entity652 , after an average of 34.3 months (range, from 12 to 88 months). Eleven of the 14 @entity1 had multiple @entity652 at the initial examination. In addition, a @entity188 was found in one male @entity1 . Of the 48 @entity1 , 17 @entity1 and 31 @entity1 , operated on for @entity14 16 @entity1 (34%) with 1.3:1 male to female ratio had 40 new @entity652 after an average of 51.8 months (range, 12 to 252 months) after the surgical excision of their @entity189 . One @entity1 had a recurrent @entity189 at the site of the @entity254 22 months after anterior resection of his @entity189 . Our data suggest that a history of @entity14 , multiple @entity652 , and male sex predict a higher risk of having future @entity14 .
