Abstract
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.
