A Prospective Randomized Comparison of the Adenoma Detection Rate With a Disposable Cap (ENDOCUFF VISION®)

The aim of this study is to evaluate the effect of ENDOCUFF VISION® (caps with soft, about 1 cm long lateral feet of rubber (\"Endocuff\") to flatten the colon folds) on ADR in a real-life setting (general practices) and in a homogenous patient collective (screening colonoscopies only). It is a prospective randomized multi centric study, with participation of at least 10 study sites (private practice). The study is an inverstigator-initiated trial (IIT). Depending on the randomization (closed envelope), the patients are examined with the standard instruments without or with ENDOCUFF VISION®. Group 1: screening colonoscopy with standard colonoscopes with ENDOCUFF VISION® Group 2: screening colonoscopy with standard colonoscopes without cap
