Intestinal metaplasia of the urinary bladder can occur within the surface urothelium due to chronic irritation in repaired exstrophic urinary bladder. Colonic villous adenomas and tubulovillous adenom...
Adenoma detection rate (ADR), a validated quality indicator (QI) of colonoscopy, does not take into account risk stratification of adenomas. Low-risk adenomas are not associated with a significantly i...
Conventional adenomas have historically been considered to be the only screening-relevant colorectal cancer (CRC) precursor lesion. The prevailing paradigm was that most CRCs arise along the chromosom...
Diminutive colorectal polyps resected during colonoscopy are sometimes histologically interpreted as normal tissue. The aim of this observational study was to explore whether errors in specimen han...
Serrated polyposis syndrome (SPS), characterized by multiple and/or large proximal serrated lesions, increases risk of colorectal cancer. Serrated lesions are often missed during colonoscopy but panch...
An observational prospective will be conducted to determine the detection rate of serrated adenoma during screening colonoscopy at our institution. Additionally, the variability of serrate...
Sessile serrated adenomas are characterized by their flat shape and the presence of a yellow mucus cap overlying the lesion. These morphological features may account for their diagnostic d...
The aim of the study is to develop a computer program which is able to automatically detect colorectal polyps in endoscopic video sequences. Furthermore, the program shall be able to autom...
This study evaluates whether the use of a disposable colonoscope attachment, Endocuff Vision, can increase the detection of sessile serrated adenomas. Participating patients will be random...
Serrated Polyposis Syndrome (SPS) is a high-risk condition for colorectal cancer (CRC). SPS patients have a cumulative CRC risk of 1.9% in 5 years despite a strict endoscopic surveillance ...
Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.
Inflammation of the COLONIC DIVERTICULA, generally with abscess formation and subsequent perforation.
Chronic or recurrent colonic disorders without an identifiable structural or biochemical explanation. The widely recognized IRRITABLE BOWEL SYNDROME falls into this category.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
A pathological condition characterized by the presence of a number of COLONIC DIVERTICULA in the COLON. Its pathogenesis is multifactorial, including colon aging, motor dysfunction, increases in intraluminal pressure, and lack of dietary fibers.
