A Study Between Two Instrument Generations to Improve Adenoma Detection in Screening Colonoscopy

"Introduction and forwarding of the device up to caecum/terminal ileum. Then withdrawal and inspection of colonic wall. Biopsies and polypectomies if necessary. overall and diagnostic (only withdrawal) times being recorded separately.~Polyps are documented with regards to location (caecum, ascending, transverse and descending colon, sigmoid and rectum), size (open forceps or snare for comparison) and morphology using the Paris classification (polypoid pedunculated or sessile, non-polypoid slightly elevated/flat/depressed, ulcerous) Polyps were then resected using biopsy forceps or cold snare (for polyps \< 5 mm), or conventional polypectomy according to local standards."
