The video shows a screening colonoscopy of a 71 year old female. Two polyps were found during the screening:
- one tubular adenoma in the cecum
- one sessile serrated Adenoma (SSA) in the ascending colon. The pit pattern of polyp number two is almost not visible under white light endoscopy but comes out with i-scan (Type II open). Since SSA show accelerated progression towards CRC, i-scan really helps to differentiate them from hyperplastic lesions.
