Endocuff for Surveillance of Serrated Polyposis Syndrome

Serrated Polyposis Syndrome (SPS) is a high-risk condition for colorectal cancer (CRC). SPS patients have a cumulative CRC risk of 1.9% in 5 years despite a strict endoscopic surveillance in specialized centers. Proximal serrated lesions are endoscopically challenging to detect due to their unremarkable morphology. Endocuff is a novel device comprised of a cap with a row of finger-like projections with a unique dynamic shape that help to flatten mucosal folds during withdrawal of the instrument in order to improve detection of lesions. Recent studies have reported an increase of detection rate and mean per patient of adenomas with Endocuff-assisted Colonoscopy compared with Standard Colonoscopy. The purpose of this study is to assess the usefulness of Endocuff-assisted Colonoscopy to detect serrated lesions in SPS patients undergoing surveillance compared to Standard Colonoscopy in a randomized fashion
