Occult Dysplasia in a Localized Giant Pseudopolyp in Crohn’s Colitis: A Case Report

Canadian Journal of Gastroenterology, 2009
Localized giant pseudopolyposis of the colon (pseudopolyp larger than 1.5 cm in size) is a rare complication of inflammatory bowel disease. There is one report of an occult carcinoma within such a lesion, and no reports of sole dysplasia.

Development of a risk scoring system for predicting advanced colorectal neoplasia within subcentimetric polyps: A population‐based study

Journal of Digestive Diseases, Volume 25, Issue 7, Page 436-443, July 2024.
The present study devised a risk score for prediction of advanced colorectal neoplasia (ACN) based on seven elementary variables, namely, age, gender, inpatient colonoscopy, chronic disease count, anemia, and other nonsteroidal anti‐inflammatory drugs (NSAIDs).

Study protocol: Population screening for colorectal cancer by colonoscopy or CT colonography: A randomized controlled trial [PDF]

, 2010
Background: Colorectal cancer (CRC) is the second most prevalent type of cancer in Europe. Early detection and removal of CRC or its precursor lesions by population screening can reduce mortality.

Colorectal cancer screening for average-risk North Americans: an economic evaluation. [PDF]

PLoS Medicine, 2010
BACKGROUND: Colorectal cancer (CRC) fulfills the World Health Organization criteria for mass screening, but screening uptake is low in most countries. CRC screening is resource intensive, and it is unclear if an optimal strategy exists.

Registration of the endoluminal surfaces of the colon derived from prone and supine CT colonography [PDF]

, 2011
Purpose: Computed tomographic (CT) colonography is a relatively new technique for detecting bowel cancer or potentially precancerous polyps. CT scanning is combined with three-dimensional (3D) image reconstruction to produce a virtual endoluminal ...

A Clinical Decision Support Framework for Incremental Polyps Classification in Virtual Colonoscopy

Algorithms, 2010
We present in this paper a novel dynamic learning method for classifying polyp candidate detections in Computed Tomographic Colonography (CTC) using an adaptation of the Least Square Support Vector Machine (LS-SVM).

Risk of cancer in small and diminutive colorectal polyps [PDF]

, 2017
The prevalence of cancer in small and diminutive polyps is relevant to “resect and discard” and CT colonography reporting recommendations. We evaluated a prospectively collected colonoscopy polyp database to identify polyps
