What this trial studies

This study evaluates the performance and safety of a new microwave-based device, MiWEndo, during colonoscopy procedures in 50 patients. The device aims to enhance the detection of colorectal polyps without altering standard clinical practices. The study is structured as a single-center, prospective, non-comparative investigation, where initial data will be collected to optimize the device's software before further assessments. The primary focus is on identifying polyps that may be missed by traditional endoscopic imaging.

Who should consider this trial

Good fit: Ideal candidates are patients with a previously detected polyp in the rectum who are referred for resection.

Not a fit: Patients at high risk for complications or those requiring urgent colonoscopy may not benefit from this study.

Why it matters

Potential benefit: If successful, this device could lead to earlier detection of colorectal polyps, potentially improving patient outcomes in colorectal cancer screening.

How similar studies have performed: While this approach has been tested in preclinical studies, its application in this specific context is novel.
