A vacuum is employed through the EndoVE as required to assist contact with the device. An electrical field depth of 8-10mm and surface area of 2cm3 is treated per pulse application. The electrical pulses are produced by an electroporation generator (ePORE device). Larger polyps will require multiple applications to ensure the full surface area has been treated. An overlap with previously pulsed areas is preferable to ensure all of the polyp tissue is ablated. The patient will then be transferred to the step-down ward to monitor for any adverse events before being discharged on the same day. The patient will be requested to attend the clinic for an endoscopy follow up at 4-6 weeks post EndoVE polyp treatment to investigate the response.",[13],"Device: Irreversible Electroporation using EndoVE(Endoscopic Vacuum Electrode) and electrical pulses generated using ePORE(electroporation device)",[15],{"type":16,"name":17,"description":18,"armGroupLabels":19,"otherNames":10},"DEVICE","Irreversible Electroporation using EndoVE(Endoscopic Vacuum Electrode) and electrical pulses generated using ePORE(electroporation device)","The use of pulsed field ablation via irreversible electroporation delivered during flexible lower gastrointestinal endoscopy",[9],[21,26],{"name":22,"role":23,"phone":24,"phoneExt":10,"email":25},"Ademola A Adeyeye, MBBS,MSc,FRCS,FEBS, FMAS, PGDE","CONTACT","02032993210","ademola.adeyeye1@nhs.net",{"name":27,"role":23,"phone":10,"phoneExt":10,"email":28},"Amyn Haji, MA,MBBChir,MSc,MD,FRCS","amynhaji@nhs.net",[30],{"facility":31,"status":32,"city":33,"state":10,"zip":34,"country":35,"countryCode":36,"cosmosGeoPoint":37,"geoPoint":42,"contacts":10},"King's College Hospital","RECRUITING","London","SE5 9RS","United Kingdom","UK",{"type":38,"coordinates":39},"Point",[40,41],-0.12574,51.50853,{"lat":41,"lon":40},{"type":44,"investigatorFullName":10,"investigatorTitle":10,"investigatorAffiliation":10,"oldNameTitle":10,"oldOrganization":10},"SPONSOR",[46],{"name":47,"class":48},"Mirai Medical","INDUSTRY","100540506","pulsed-field-ablation-of-colorectal-polyps-100540506",false,"NCT06317727","PULSed Field ablAtion of coloRectal Polyps","Pulsed Field Ablation of Colorectal Polyps","PULSAR","Inclusion Criteria:\n\n* \\> 18 years of age.\n* Ability to review the consent form prior to enrolment into the study • Patients must be mentally capable of understanding the information given • Patients must give written informed consent prior to undergoing any study-specific procedures.\n* Patients must have at least one polyp (treatment naive, recurrent or residual) measuring \\>5mm, located distal to the splenic flexure(i.e descending colon, Sigmoid colon, recto sigmoid junction and the rectum above the dentate line)\n* Polyp(s) must be classified as Type 1 or Type 2, based on NICE (Narrow Band Imaging International Colorectal Endoscopic) classification; OR Type 1 or Type 2A \u002F2B based on JNET (Japan Narrow Band Imaging Expert Team) classification\n* Patients must have a World Health Organization (WHO) performance status ≤ 2 .
