Trial Identification

Brief Title: Trial on Innovative Technologies in Colonoscopy

Official Title: Prospective Randomised Trial Comparing New Technologies of Endoscopic Bowel Visualisation With Conventional Colonoscopy.

Study ID: NCT01688557

Conditions

Polyps

Neoplasms

Inflammatory Bowel Disease

Interventions

Innovative colonoscopy (Olympus CF-HQ190F, NBI + Dual Focus)

Conventional colonoscopy (Olympus CF-H180DL)

Study Description

Brief Summary: The trial will compare results of screening colonoscopy performed by means of conventional colonoscopy and using new visualisation techniques during endoscopic examination. * Electronic colonoscopes Olympus CF-HQ190F with following options: magnetic positioning (Scope Guide), responsive insertion technology (RIT), dual focus function, narrow band imaging (NBI) will be used for innovative colonoscopies * Electronic colonoscopes Olympus CF-H180DL with Scope Guide and NBI options will be used for conventional colonoscopies Endoscopists will archive all images and establish presumptive diagnosis based on the results of different visualisation techniques. All endoscopes will be attached to Olympus Evis Exera III system. Biopsy of all pathological lesions will be performed to establish final diagnosis. The main outcome measure is diagnostic accuracy of innovative colonoscopy in comparison with conventional technique.

Detailed Description: A total of 600 consecutive patients undergoing screening unsedated colonoscopy will be randomly assigned to innovative or conventional examination. Randomization will be based on computer-generated randomization lists. All patients will be blinded so they will not know which techniques will be used to assess lesions found in colon. In innovative colonoscopy group narrow band imaging (NBI) and Dual Focus (DF) function will be used to identify and classify all lesions acc. to Sano and Kudo classification. Endoscopic biopsy will be taken from all lesion and endoscopic diagnosis will be compared with final histological diagnosis. Thus sensitivity, specificity, diagnostic accuracy, predictive values, likelihood ratio and Youden index will be calculated. As secondary endpoints total examination time, coecal intubation rate and pain intensity (VAS scale) will be established. This study will help to establish whether new technologies used during colonoscopy may improve diagnostic possibilities and whether they prolong examination time or lead to increase of pain intensity afterwards.
