Abstract

Current efforts are directed toward improving quality metrics such as adenoma/polyp detection rates during colonoscopy to decrease the incidence of colorectal cancer.¹ Previous studies have reported variable detection rates for adenomas/polyps during colonoscopy for active participation/observation by nurses, trainees, and/or technician (dual observer [DO] group) with an endoscopist.²^,³ We performed a systematic review and meta-analysis to evaluate the detection rate of adenomas/polyps during colonoscopy via DO versus single observers (ie, endoscopist alone).
