Comparative Study of Postprocessing Imaging Systems for Diminutive Colonic Polyps

2014-08-27 03:13:20 | BioPortfolio


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).

Several previous studies have indicated that NBI without magnification can be useful for real-time differentiation of diminutive colonic neoplasias.

To date, however, there are no studies comparing NBI with other imaging systems (FICE or i-Scan) for differentiation of diminutive colonic polyps.

The study objectives are to compare the diagnostic efficacy of NBI with that of i-Scan in real-time prediction of diminutive colonic polyps.

In this prospective pilot study, diminutive colonic polyps detected during colonoscopy will be observed with conventional colonoscopy, thereafter will be observed with new imaging systems.

Sensitivity, specificity, and diagnostic accuracy of both NBI and i-Scan will be assessed by reference to histological results obtained by endoscopic biopsy or polypectomy.

Medical and Biotech [MESH] Definitions

The act of regarding attentively and studying facts and occurrences, gathering data through analyzing, measuring, and drawing conclusions, with the purpose of applying the observed information to theoretical assumptions. Observation as a scientific method in the acquisition of knowledge began in classical antiquity; in modern science and medicine its greatest application is facilitated by modern technology. Observation is one of the components of the research process.

Controlled operation of an apparatus, process, or system by mechanical or electronic devices that take the place of human organs of observation, effort, and decision. (From Webster's Collegiate Dictionary, 1993)

Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.

The study of natural phenomena by observation, measurement, and experimentation.

The concept of new knowledge acquisition through observation and interaction with others.
