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)

Interventions

MiWEndo System (Device)
All colonoscopies will be performed with high-definition technology. The MiWEndo System will be fitted to the tip of the endoscope before colonoscopy is started and connected to the microwave processor unit. Endoscopies will be performed by experienced endoscopists who will be previously trained on the use of the MiWEndo System. The MiWEndo Analyzer will be managed by the assistant. At the beginning of the extubation, the MiWEndo System will be turned on and the endoscopist will put music headphones on (blind to the results of MiWEndo). In case one of them identifies a polyp, the exploration will be stopped and check if it has been detected by the alternative method as well. All the polyps will be resected and sent to the Pathological Department for histological analysis following the usual clinical practice. A stopwatch will be used to measure both total procedure time and withdrawal time.

Eligibility 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.
