Irreversible electroporation with endoluminal balloon catheterin perihilar region: preliminary results

Popis výsledku v původním jazyce

Purpose: To evaluate the safety and efficacy of endoluminal irreversible electroporation (IRE) in biliary tract performed with a balloon catheter in the perihilar region. Material and methods: Endoluminal IRE of the common bile duct was performed in 5 domestic swine using a balloon catheter inserted during laparotomy. IRE catheter consists of 3 electrodes with the length of 1 cm, attached around an inflatable balloon at 120 degrees. IRE was performed with parameters of 50-90 pulses of 1500-2000V delivered between each couple of electrodes. All swine models were slaughtered 3 days after the procedure. Imaging study using MRI and histopathologic follow-up was performed. Results: The balloon insertion and IRE procedure was successful in all porcine models. All animals survived for the designated period of 3 days. Periablation edema in hepatoduodenal ligament and adjacent liver tissue measured on postprocedural MRI ranged from 13 to 40 mm in maximum diameter, 2, 5-18, 7 ml in volumetric assessment.
