- Age
- Older than 18 years
- Sex
- All sexes can join
- Disease stage
- High risk of colorectal cancer or polyps, for example a positive faecal occult blood test, earlier removed polyps under surveillance, hereditary polyposis syndromes, Lynch Syndrome or familial cancer

- High risk of major complications such as perforation or bleeding
- Suspected or proven lower gastrointestinal bleeding
- Clotting problem that cannot be corrected, or anticoagulant/clopidogrel therapy during the procedure

- Original description
The study involves the planned use of a new microwave-based device during colonoscopy procedures in 50 patients to assess the performance and safety of its use for detection of colorectal polyps and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies (including phantom studies, an ex vivo study with human tissues, and an in vivo study with porcine model) and in a pilot study in humans (NCT05477836)Read full original descriptionShow less
Performance and Safety of MiWEndo-assisted Colonoscopy: MiWEndo II (Pivotal Study)
The study involves the planned use of a new microwave-based device during colonoscopy procedures in 50 patients to assess the performance and safety of its use for detection of colorectal polyps and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies (including phantom studies, an ex vivo study with human tissues, and an in vivo study with porcine model) and in a pilot study in humans (NCT05477836)
Inclusion: 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: 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.
