Detection Rate of Serrated Adenomas in Screening Colonoscopy

Colonoscopy screening is a preventative measure for colorectal carcinoma (CRC), a highly malignant and dangerous cancer. Extensive research on the adenoma detection rate has provided national standards and quality metrics to help assess competence of endoscopists. Currently, there are no standards established for serrated adenomas. The proposed study would be conducted at Good Samaritan Hospital (GSH) and TriHealth Surgery Center West. This is an observational study and does not involve any patient interventions. However, because patient healthcare data will be collected for research, informed consent will be obtained shortly before the procedure. The main study objective is to determine the detection rate of serrated adenoma during screening colonoscopy at our institution. Additionally, the variability of serrated adenoma detection among endoscopists will be evaluated and the characteristics of serrated adenomas will be described.
