Patient age 45 year old and above who presented with rectal bleeding at three tertiary hospitals in South West Nigeria were invited for colonoscopy. The clinical information of the patients and the colonoscopy data were analyzed
Patient age 45 year old and above who presented with rectal bleeding at Obafemi Awolowo University Teaching Hospitals Complex, Ile Ife, Nigeria, University College Hospital, Ibadan, Nigeria, and University of Ilorin Teaching Hospital, Ilorin Nigeria were invited for colonoscopy. Categorical variables were compared using χ2-test or Fisher's exact test while the Kruskal-Wallis test was used for quantitative variables. Multivariate analysis was performed using logistic regression model. All statistical tests were two-sided and p-values below 0.05 were considered statistically significant. Statistical analysis was carried out using SAS 9.4 and R 3.3.1.

To determine colonoscopy polyp and cancer detection rate
The hypothesis for this study was that colonoscopy surveillance of a high-risk cohort of patients with rectal bleeding would demonstrate that 10-20% of these patients have pre-malignant colorectal polyps(adenomas) or cancers.
Time frame: 2 years
To detect colorectal cancer early using symptoms based assessment
The long-term impact of identifying at risk patients and patients with early stage cancers may be a reduction in mortality from colorectal cancer in low- and middle- income countries
Time frame: 2 years
