THE LONG TERM IMPACT OF ROUX-EN-Y GASTRIC BYPASS SURGERY ON COLORECTAL CANCER: A FOURFOLD INCREASE IN RISK OF SERRATED COLONIC NEOPLASIA

s28), and 5-10 years to 10 years (n=8).Reviewers shortened intervals from 10 years to 1 year (n=1), 10 years to 5 years (n=2), 5 years to 1 year (n=1), 5 years to 3 years (n=9), and 3 years to 1 year (n=3).Inter-rater reliability among reviewers revealed an overall 71% agreement for the revised follow up intervals.CONCLUSIONS: We found moderate differences between initial provider and secondary reviewer recommendations for surveillance interval.Providers tended to recommend shorter intervals which could lead to unnecessary earlier colonoscopies and place a strain on resources in this safety net health system.Interrater reliability was fair.Most differences seemed to hinge on recommending 5 years versus 5-10 year surveillance intervals.Better adherence to evidence-based follow-up interval can improve efficient resource utilization within the safety net care system.
