Investigator's goal is to collect data from the endoscopy reports and clinic station reports to complete a descriptive analysis of the demographics, colonoscopy procedure performance, and assess the type of benign colon polyps detected during screening and surveillance from 02/01/2000 - 12/31/2020.
Specific variable to be reviewed:
- Patient Demographics: Age, Sex, Race, Height, Weight, BMI (patient privacy will be acknowledged).
- Indications for Colonoscopy (screening, surveillance, symptoms or tertiary referral [EMR])
- Comorbid conditions: , cancer and surgical history, medical conditions,
- Colonoscopy procedure; quality of colon preparation (using the Boston Bowel Preparation Scale) 0 - 3 for each section of the colon (Ascending, Transverse, Descending and Total Colon) , cecal intubation rate, cecal intubation and total procedure time, type of colonoscope (if CO2 was used in the procedure and techniques for colonoscope insertion, including position changes.
- Examination findings: number of polyps and nature of polyps removed (site, size, surface, vascular pattern); type of polyp removed (serrated and sessile (flat) ; optical features and histology of polyps.
- Resection techniques: biopsy, snare resection, endoscopic mucosal resection etc.
- Including Pathology report findings so that a comparison can be made of the optical features and actual pathology report.
- Outcomes of colonoscopy: adenoma detections (tubular and villous), cancer and quality metrics.
- Outcome of colonoscopy: Complications (Bleeding and performance).

Data collected from endoscopy reports to complete a descriptive analysis of demographics, colonoscopy procedure performance, and assess type of benign colon polyps detected during screening and surveillance from 02/01/2009 - 12/31/2020.
Other: Chart Review
Retrospective and prospective data review of colonoscopy procedures, examination findings, resection techniques, and pathology reports.
- Polyp Detection in Colon Cancer Screening and Surveillance [ Time Frame: 9 years ]Descriptive tables presented for demographics, polyp counts, colonoscopy experiences, polyp removals and findings. Proportions presented with 95% confidence intervals. Continuous values such as age and times presented with median, minimum and maximum. Comparisons among patient subgroups made with chi-square tests for categorical data and t-tests or the non-parametric alternative, Wilcoxon tests, to compare continuous measures. Graphics such as box plots, trellis plots, bar graphs, or stacked bar graphs used to describe distributions overall and among subgroups.
