Quality assessment of the colon consists of detailed, systematic and meticulous inspection of the entire colonic mucosa. A thorough and careful mucosal inspection is essential to prevent colorectal cancer (CRC) and cancer-related mortality.1 The detection and resection of precancerous polyps is the primary goal of screening colonoscopy. Recently, there has been a focus on quality and safety of colonoscopy. Worldwide, the demand for colonoscopy is increasing, and with a limited workforce, efficient working is of paramount importance.2
Quest for a colonoscopy efficiency marker
We performed an extensive search in the literature for the definition of colonoscopic efficiency (CE); however, no clear definition was found. We propose the following working definition as ‘the ability to detect clinically significant pathologies within acceptable time limits without compromising the quality or safety of the examination’.
CE is augmented by the following factors: optimal bowel preparation, technical ease of the procedure, technique of the endoscopist, high-definition and high-quality video imaging, and uninterrupted panoramic view of mucosal surface.
Although mucosal views may be improved with dynamic position changes and routine retroflexion in the rectum, these manoeuvres may not be effective in narrower colonic segments and flexures.3
Recent technological developments in the field of colonoscopy such as wide-angle view colonoscopes and disposable distal attachments (Endocuff Vision, transparent cap and Endorings) helped to improve the lateral and backward view of the mucosal folds.4–9
These advancements demonstrated an improvement in the quality and performance of the procedure. However, none of the studies explored the impact on CE of the technologies. We aimed to assess the performance of a new marker of colonoscopic efficiency. We propose SP6 (number of significant polyps detected per 6 min withdrawal time during colonoscopy) as …
