Brief Summary:
The aim of the study is to study the risk of colorectal cancer and polyps in people older than 80 years compared to the younger age group. The researchers hypothesized that colonoscopy in older people is likely to have more complications without detection of a significant number of large polyps and cancer.

Patients older than 80 years presenting for average risk screening or surveillance colonoscopy
Patients younger than 80 years presenting for average risk screening or surveillance colonoscopy

Primary Outcome Measures :
  1. Proportion of elderly patients (>80 yrs) with colorectal neoplasia [ Time Frame: 2 years ]
  2. proportion of patients with complications including perforation, bleeding, MI or CVA within 24 hours of colonoscopy in >80 vs. <80 agr group [ Time Frame: 2 years ]

Secondary Outcome Measures :
  1. Five year disease free survival and five year mortality rates after the diagnosis of colon cancer in older (>80 yrs) vs. younger group (<80 yrs) [ Time Frame: 2 years ]
