Screening colonoscopy is considered the gold standard for adenoma detection in the colon. However, it has been shown that a considerable number of polyps can be missed during screening col...
Colonoscopy( examining the colon with a flexible tube and a camera ) is usually done for screening purposes to find any precancerous lesions (polyps) at an early stage. During the colonosc...
Several novel imaging technologies are currently used for detection and differentiation of colonic polyps during colonoscopy, such as NBI (Olympus), FICE (Fujinon), and i-Scan (Pentax). ...
A withdrawal time of at least 6 minutes has been considered to be necessary to guarantee the adenoma detection rate and the critical quality criterion of colonoscopy. However, several larg...
Optical Enhancement Technology might be superior to the conventional HD-WL in detecting colorectal adenomas
Although water exchange may improve adenoma detection when compared to CO, it is unclear whether water is a better medium to fill the lumen during withdrawal and visualize the mucosa. Total underwater...
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...
Adenoma detection is a highly personalized task that differs markedly between endoscopists. Technical advances are therefore desirable for the improvement of the adenoma detection rate (ADR). An autom...
Accurate sizing of polyps and improving adenoma detection rates (ADR) are important goals for high-quality colonoscopy. Surveillance intervals are based on accurate sizing of polyps. There are no clin...
Incomplete resection of polyps could be an important cause of post-colonoscopy colorectal cancer. However, it is difficult to study progression of incompletely removed polyps or their clinical importa...
Physiological and psychological symptoms associated with withdrawal from the use of a drug after prolonged administration or habituation. The concept includes withdrawal from smoking or drinking, as well as withdrawal from an administered drug.
Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (From Last, Dictionary of Epidemiology, 2d ed)
Discrete tissue masses that protrude into the lumen of the COLON. These POLYPS are connected to the wall of the colon either by a stalk, pedunculus, or by a broad base.
Physiologic or biochemical monitoring of the fetus. It is usually done during LABOR, OBSTETRIC and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery.
Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations.
