Detaljert beskrivelse
The Given® Diagnostic System offers an alternative approach for endoscopic visualization of the colon using capsule endoscopy, a swallowable device which contains imagers, light sources, a power source and a RF transmitter. Advantages of the Given® Diagnostic System include the elimination of the need for conscious sedation, the minimally invasive, painless nature of the exam, and the ability to pursue normal daily activities immediately following the procedure . This multi-center prospective, cohort study will evaluate the performance of PCCE in visualizing the colon. Up to 394 subjects will participate in this study. All subjects to be enrolled will be appropriate candidates for standard colonoscopy based on their clinical indication.
Each subject will undergo PCCE. All generated PCCE RAPID videos will be reviewed by blinded PCCE reading physicians. All readers, experienced in PillCam SB, will have undergone standardized training and passed a qualification test specific to reading and interpreting PCCE videos. Training will be done by reading at least 5 cases to demonstrate proficiency in interpretation of PCCE. PCCE results will be compared with that of a colonoscopy procedure.
Following PCCE procedure, standard colonoscopy will be performed by a colonoscopist blinded to the results of the PCCE. The colonoscopist will be "unblinded" during the standard colonoscopy procedure at three locations on withdrawal of the colonoscope.
Primary Endpoint - Accuracy parameters (sensitivity, specificity, NPV, PPV) of PCCE compared to standard colonoscopy.
• Number, type and severity of adverse events with both PCCE and standard colonoscopy
