Computational intelligent systems could reduce polyp miss rate in colonoscopy for colon cancer diagnosis and, thus, increase the efficiency of the procedure. One of the main problems of existing polyp localization methods is a lack of spatio-temporal stability in their response. We propose to explore the response of a given polyp localization across temporal windows in order to select those ima...
background: the incidence of colorectal cancer is rising in several developing countries. in the absence of integrated endoscopy and pathology databases, adenoma detection rate (adr), as a validated quality indicator of screening colonoscopy, is generally difficult to obtain in practice. we aimed to measure the correlation of polyp-related indicators with adr in order to identify the most accur...
BACKGROUND Although colonoscopy is the criterion standard for detecting colorectal adenomas and cancers, a significant percentage of adenomas are missed. OBJECTIVE To compare forward-viewing with ultrawide-viewing colonoscopy in the detection of simulated colon polyps in an in vitro colon model. DESIGN Prospective, multicenter. SETTING Six endoscopy units (3 in the United States and 3 in ...
Background and study aims Up to 25 % colorectal adenomas are missed during colonoscopy. The aim of this study was to investigate whether the endocuff could improve polyp detection in an organized bowel cancer screening program (BCSP). Patients and methods This parallel group, single-blinded, randomized controlled trial included patients with positive fecal occult blood test (FOBT) who were atte...
Gender, age, and concomitant diseases of melanosis coli in China: a multicenter study of 6,090 cases
Backgrounds and Aims Melanosis coli (MC) is a noninflammatory, benign, and reversible colonic disorder, but its detection rates in China are unclear. We therefore aimed to analyze the epidemiological characteristics of MC in China. Methods We assessed the detection rates, associated factors and concomitant diseases of MC in the patients who underwent colonoscopy at eight medical centers acros...
