Summary
Brief summary (as posted)
The investigators are retrospectively comparing detection rates of adenomatous polyps, advanced adenomas, and size assessment of the polyps among Rush University Medical Center endoscopists. The investigators plan to review whether the size assessment of adenomatous polyps affected the surveillance protocols and if the location of polyps detected affected the detection rates.

Arms (0)
[]Primary outcomes (2)
- measure
- Adenomatous Polyp Detection Rate
- timeFrame
- one year
- description
- Assessing for advanced adenomas (including location).
- measure
- Endoscopic Size Assessment Versus Pathological Size Assessment
- timeFrame
- one year
- description
- Size of polyps at time of endoscopic procedure will be compared to the size of the same polyp by pathological assessment.
Secondary outcomes (1)
- measure
- Retroflexion as an indication of adenoma detection rate in colorectal cancer screening
- timeFrame
- one year
- description
- Retroflexion is a common but not mandatory practice in colonoscopy which as not been systematically studied in terms of polyp detection. Charts will be reviewed to determine whether retroflexion was performed.
