Data on performance characteristics of flexible sigmoidoscopy (FS) between age groups are limited. This study evaluates screening FS in subjects 75 years of age (elderly) compared with ages 50-74 years (general screening population). Data were collected on patient characteristics, insertion depth, procedural difficulties, complications, and endoscopic findings. There was an increased rate of endoscopist-reported limitations (50.4%vs. 34.9%; P = 0.0001) and incomplete examinations (15.6%vs. 5.4%; P = 0.0001) in the elderly cohort relative to subjects aged 50-74. The complication rate (1.0%vs. 1.5%; P = 0.53), adenoma detection rate (7.2%vs. 5.6%; P = 0.213), and advanced adenoma detection rate (0.71%vs 0.65%; P = 0.86) were similar. More carcinomas were detected in the elderly (0.53%vs. 0.06%; P = 0.042). Factors associated with incomplete examinations in the elderly included age, female gender, and poor bowel preparation. Despite technical difficulties, FS in the elderly is safe and detects significant pathology.
