Does high resolution colonoscopy in a bowel cancer screening program improve polyp detection? Context: To compare high resolution colonoscopy (Olympus Lucera) with a megapixel high resolution system (Pentax HiLine) as an in-service evaluation. Polyp detection rates and measures of performance were collected for 269 colonoscopy procedures. Five colonoscopists conducted the study over a three month period, as part of the United Kingdom bowel cancer screening program. There were no differences in procedure duration (χ² P = 0.98), caecal intubation rates (χ² P = 0.67), or depth of sedation (χ² P = 0.64). Mild discomfort was more common in the Pentax group (χ² P = 0.036). Adenoma detection rate was significantly higher in the Pentax group (χ² test for trend P = 0.01). Most of the extra polyps detected were flat or sessile adenomas.

Megapixel definition colonoscopes improve adenoma detection without compromising other measures of endoscope performance. Increased polyp detection rates may improve future outcomes in bowel cancer screening programs. Final Decision: yes
