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.

This randomized phase II/III trial studies how well lenalidomide works and compares it to observation in treating patients with asymptomatic high-risk asymptomatic (smoldering) multiple my...
The main objective of this project is to evaluate the effectiveness of Observation of Action (Action Observation, AO) both in increasing the speed of movement of the upper limbs, agility a...
RATIONALE: Observation is closely monitoring a patient's condition and not giving treatment until symptoms appear or change. Observation may help doctors see how effective surgery is in tr...
Action observation involves the observation of an action followed by an attempt to replicate it. Recent studies show that increased sensorimotor cortical connectivity improves motor performance via ob...
Observation stays are increasingly common, yet no standard method to identify observation stays in Medicare claims is available, including events with status change. To determine the claims patterns o...
This Letter reports on the experimental observation of a topologically protected edge state and exceptional point in an open and non-Hermitian (lossy) acoustic system. Although the theoretical underpi...
Action observation activates brain regions involved in sensory-motor control. Recent research has shown that action observation can also facilitate motor learning; observing a tutor undergoing motor l...
Mu desynchronization is the attenuation of EEG power in the alpha frequency range recorded over central scalp locations thought to reflect motor cortex activation. Mu desynchronization during observat...
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.
