Contact Admin. Colonoscopy is an important diagnostic and screening tool for colorectal cancer detection and prevention, and adequate bowel preparation is critical for successful colonoscopy.
Complications related to colonoscopy are increased in elderly patients, either directly or indirectly related to the procedure, and the risks and benefits of colonoscopy procedures need to be carefully considered in these patients.

Methods for achieving safe and adequate bowel preparations in the elderly include clear instructions, reminder calls, and case management for potential confounding patient related factors.
