Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with a previously detected polyp in the rectum who are referred for resection.
✕Probably not a fit
Patients at high risk for complications or those requiring urgent colonoscopy may not benefit from this study.

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.
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 gone: While this approach has been tested in preclinical studies, its application in this specific context is novel.
Who can join: the full rules
Show full inclusion / exclusion criteria
Inclusion Criteria: \- Patients older than 18-year-old referred for a screening or surveillance colonoscopy because of a high-risk condition of developing colorectal cancer or having colorectal polyps as fecal occult blood test (FOBT) positive, previously resected polyps under surveillance, hereditary polyposis syndromes, Lynch Syndrome or familial cancer. These criteria will ensure the probability of finding polyps during the explorations. All the patients will give written informed consent. Exclusion Criteria: * Patients at a high risk of having major complications as perforation or hemorrhage, suspected or proven lower gastrointestinal bleeding, non-correctable coagulopathy or anticoagulant/clopidogrel therapy during procedure, inadequate bowel cleansing. * ASA-IV patients. * Urgent colonoscopy.
