The American Society for Gastrointestinal Endoscopy (ASGE)/American College of Gastroenterology Task Force (ACGTF) on Quality in Endoscopy released updated quality benchmarks for colonoscopy in 2015. Our initial study concluded that surgery residents could perform safe and competent screening colonoscopy within a structured endoscopy curriculum. In this follow-up study, we sought to determine whether surgery residents could achieve the increased adenoma detection rate (ADR) benchmarks endorsed by the ASGE/ACGTF. An Institutional Review Board-approved prospective analysis of colonoscopies performed by five postgraduate year 2 and 3 general surgery residents from 2013 to 2015 was completed. All colonoscopies were performed under the direct supervision of surgical endoscopists after each resident passed a structured endoscopy simulation curriculum. The following ASGE/ACG quality metrics were recorded: bowel preparation quality; cecal intubation rate; polyp and ADRs; and, complications. Power analysis determined that 108 procedures were required for an 80 per cent probability of data analysis accuracy. About 135 screening and diagnostic colonoscopies were performed. Bowel prep was considered “adequate” in 90 per cent of cases. The cecum was reached independently in 95 per cent of cases. Polyp(s) were visualized and removed in 39 per cent of patients. The overall ADR was 31.8 per cent (>25%). Male ADR was 38.7 per cent (>30%). Female ADR was 26.0 per cent (>20%). Average polyp size was 8.7 mm (range: 1‐22 mm). One patient was readmitted for postpolypectomy syndrome, and successfully managed nonoperatively. In conclusion, using our structured endoscopy curriculum, surgery residents achieved ADRs fully consistent with the updated benchmark values endorsed by the ASGE/ACGTF.
