OBJECTIVE: @entity8364 ( @entity8364 ) screening for @entity14 ( @entity14 ) is associated with reduced mortality from @entity14 . It is unknown whether @entity8364 is equally effective in @entity1 and @entity1 , but differences in anatomy and perception of @entity158 may increase the difficulty of performing @entity8364 in @entity1 . The aim of this study was to determine factors associated with a shorter or limited screening @entity8364 . METHODS: @entity1 referred by their primary care provider were eligible for screening sigmoidoscopy if they were 50 yr or older with negative fecal occult blood tests and no first-degree relative with @entity14 at age 55 yr or younger. A detailed questionnaire regarding demographic characteristics and risk factors for @entity14 , @entity117 and multivitamin use, and previous abdominal surgery was completed by the @entity1 on a standardized form before their procedure. The histologic type ( @entity5072 , @entity2513 ) of each polyp was recorded. Depth of examination (in cm) was recorded based on the standardized markings on the shaft of the sigmoidoscope when it was thought to be in a straight position. Limitations to the examination (angulation, @entity158 , and poor preparation), other mucosal findings, and complications were also noted. RESULTS: A total of 3980 @entity1 (52% female) were prospectively enrolled in a screening program over a 22-month period. @entity1 were more likely than @entity1 to report previous pelvic or abdominal surgery (OR = 2.64, 95% CI = 2.29-3.05) and were less likely to have had a previous sigmoidoscopy (OR = 0.71, 95% CI = 0.61-0.83). Females were almost twice as likely as males to have a procedure limited in some way (angulation, @entity2473 , or @entity158 ) (OR = 1.86, 95% CI = 1.63-2.13). When defined by depth of examination, females were significantly more likely than males to have a procedure of <50 cm (OR = 1.93, 95% CI = 1.63, 2.29) and were less likely to have an @entity6523 or @entity5 detected (OR = 0.55, 95% CI = 0.42-0.71). The average endoscopy distance for @entity1 was 52.3 cm, compared with 55.2 cm in @entity1 (p < 0.0001), and the average number of @entity1127 detected in @entity1 was 1.4, compared with 1.56 in @entity1 (p = 0.003) among @entity1 with at least one polyp. Using multivariable analysis, females were more likely to have an examination of <50 cm compared with @entity1 , controlling for age, @entity2473 or @entity158 on examination, previous surgery, angulation of the colon, and type of endoscopist- @entity601 or nonphysician endoscopist (OR = 1.67, 95% CI = 1.41-1.99). CONCLUSIONS: @entity1 are more likely than @entity1 to have a shorter and more limited @entity8364 . This is partly owing to @entity694 and @entity158 during the examination. Methods aimed at reducing @entity158 and improving maneuverability in an angulated colon during @entity8364 may improve the effectiveness of @entity14 screening in @entity1 .
