14% Increased ADR
How Can Olympus Technology Help?
The Olympus digital platforms EVIS X1, EVIS EXERA III and EVIS LUCERA ELITE provide superior illumination for NBI and thus enable better observation of the colon.
A meta-analysis involving 11 studies with 4,491 patients demonstrates that NBI in digital platforms outperforms white light imaging in ADR. 49
Efficient reporting of polyp histology is critical to monitor ADR. NBI enables high-confidence optical diagnosis and fulfills the ASGE PIVI criteria for implementing a RESECT & LEAVE and RESECT & DISCARD strategy for diminutive colorectal polyps (<5 mm). 22,23,24 As a result, European and American gastroenterology societies have endorsed the use of NBI for optical diagnosis of colorectal polyps (ESGE, ASGE, and NICE). 25,26,48
ADR is a cumulative indicator which is influenced by a number of demographic, procedural, and equipment-related factors. ADR is influenced by gender
and differs between facilities depending on their patient demography. Various procedural factors such as withdrawal time
, preparation quality
, and use of water-exchange colonoscopy
, as well as the use of HDTV equipment
were identified to significantly increase ADR.
To properly report and monitor ADR, feedback from histology is required. Accordingly, additional time and effort is needed to adjust patient records once the histology results are known.
