ENDOSCOPIC ULTRASOUND-GUIDED RADIOFREQUENCY ABLATION AND COIL PLACEMENT PLUS CYANOACRYLATE INJECTION IN THE FEEDER VESSEL OF HEPATOCELLULAR CARCINOMA – A NEW TECHNIQUE IN ENDOHEPATHO

Video Summary

A new endoscopic ultrasound-guided technique combining radiofungal ablation, coil placement, and cyanoacrylate injection shows promise in treating hepatocellular carcinoma, especially in patients contraindicated for liver transplantation. This approach targets tumors larger than 3 cm, particularly those difficult to treat percutaneously, by using local regional therapies to manage tumor burden. The procedure successfully involved arterial embolization and radiofrequency ablation guided by ultrasound. In two patient cases, the technique demonstrated technical success, though certain device limitations and an instance of thermal injury occurred. Follow-up imaging confirmed effective treatment, underscoring the potential of this approach, pending further validation studies.
