Simple feedback of colonoscopy performance improved the number of adenomas per colonoscopy and serrated polyp detection rate

Determining the adenoma detection rate and adenomas per colonoscopy by photography alone: proof-of-concept study.

BACKGROUND AND STUDY AIMS The adenoma detection rate (ADR) and adenomas detected per colonoscopy (APC) are measures of the quality of mucosal inspection during colonoscopy. In a resect and discard policy, pathologic assessment for calculation of ADR and APC would not be available. The aim of this study was to determine whether ADR and APC calculation based on photography alone is adequate compa...

Inverted sessile serrated polyp diagnosed by magnifying image-enhanced colonoscopy.

Assessing bowel preparation quality using the mean number of adenomas per colonoscopy.

INTRODUCTION The quality of the bowel preparation directly influences colonoscopy effectiveness. Quality indicators are widely employed to monitor operator performance and to gauge colonoscopy effectiveness. Some have suggested that the enumeration of the mean number of adenomas per colonoscopy (MNA) may be a more useful measure of bowel preparation quality, but evidence of the utility of this ...

Texture-Based Polyp Detection in Colonoscopy

Colonoscopy is one of the best methods for screening colon cancer. A variety of research groups have proposed methods for automatic detection of polyps in colonoscopic images to support the doctors during examination. However, the problem can still not be assumed as solved. The major drawback of many approaches is the amount and quality of images used for classifier training and evaluation. Our...

GPU-accelerated Polyp Detection in Virtual Colonoscopy

Nowadays, Virtual Colonoscopy (VC) is an important non-invasive alternative for the study of the colon. Substantial research efforts have been dedicated to this method, and one of the major challenges has always been producing accurate results in a short period of time. One of the most crucial phases of VC is the detection of polyp candidates, where possible lesions on the colon walls are autom...
