Background To improve detection of mucosal lesions during colonoscopy a number of
imaging modalities have been suggested, including high definition and virtual …

Background and Aims Mucosal exposure devices including distal attachments such as the
cuff and cap have shown variable results in improving adenoma detection rate (ADR) …

Colonoscopy is a dominant modality for colorectal cancer (CRC) prevention in average-risk
patients aged 50 years and older. The principal benefits of screening colonoscopy are that it …

Background: Causes of missing lesions during colonoscopy include lesions hidden behind
folds and subtle lesions in the visual field that cannot be readily seen (eg flat and depressed …

BACKGROUND: Small polyps are routinely missed during colonoscopy even with careful
examination. AIM: To determine and compare endoscopic efficiency and polyp miss rate …

BACKGROUND: Missing adenomas and the inability to accurately differentiate between
polyp histology remain the main limitations of standard-definition white-light (SD-WL) …

Colonoscopy is the gold standard for colorectal cancer prevention; however, it is still an
imperfect modality. Precancerous lesions can be lost during screening examinations, thus …

BACKGROUND Colon cancer is the second leading cause of cancer death in the United
States. 1 Colonoscopy is used to screen for colon cancer and adenomatous polyps. 2, 3 …

Background & Aims: High-resolution colonoscopy with chromoscopy (HRC) is a technique
designed to improve the detection of colonic neoplasias. We prospectively compared …

OBJECTIVES: The benefits of narrow band imaging (NBI) on enhancing colorectal adenoma
detection remain questionable. We tested whether the new generation of NBI (190-NBI) …
