Summary: | AIM: To compare high resolution colonoscopy (Olympus Lucera) with a megapixel high resolution system (Pentax HiLine) as an in-service evaluation. METHODS: 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. RESULTS:There were no differences in procedure duration (x^2 p = 0.98), caecal intubation rates (x^2 P = 0.67), or depth of sedation (x^2 P = 0.64). Mild discomfort was more common in the Pentax group (x^2 p = 0.036). Adenoma detection rate was significantly higher in the Pentax group (x^2 test for trend P = 0.01). Most of the extra polyps detected were flat or sessile adenomas. CONCLUSION: 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. |
