Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Phase I 1) Maximum diameter of the resection specimens retrieved with the Captivator EMR - and Duette devices. Phase II 1) Percentage of successful endoscopic resection (i.e. resection of all lesion delineation markings) | — |
Secondary
| Measure | Time frame |
|---|---|
| Phase I 1) Difference in the number of device or procedure related complications, such as bleeding or perforation, experienced with the CaptivatorTM device compared to the DuetteTM device. 2) Visibility of the CaptivatorTM device and the DuetteTM device (pre- and post-procedure). 3) Ease of endoscopic resection 4) Procedure time Phase II 1) Number and severity of any acute (during procedure) or early (0-48 hours) device or procedure related complications such as bleeding or perforation during endoscopic resection with the CaptivatorTM device. Complications are registered only if they are clinically significant. 2) Presence of any late complications (> 48 hours) such as bleeding or perforation during endoscopic resection with the CaptivatorTM device. Complications are registered only if they are clinically significant. 3) Procedure time | — |
