Thermal ablation for hepatic tumors in high-risk locations - 07/03/24
Highlights |
• | Artificial ascites, non-touch multibipolar ablation, and laparoscopy-assisted thermal ablation can be used to improve ablation outcomes for subcapsular tumors. |
• | For perivascular tumors, no-touch multi-applicator and microwave ablation techniques are less prone to the heat-sink effect. The heat-sink effect can be decreased further by performing the Pringle maneuver during laparoscopy-assisted thermal ablation. |
• | For peribiliary tumors, intraductal chilled fluid perfusion through a nasobiliary duct can be performed to improve the outcomes of thermal ablation. |
• | Cryoablation and Irreversible electroporation are relatively new ablation techniques that can be used as alternatives to overcome the limitations of RF and MW ablation for perivascular and peribiliary tumors. |
Abstract |
Thermal ablative techniques such as radiofrequency and microwave ablation are minimally invasive and cost-effective approaches that are currently being adopted as alternatives to surgical resection for primary and metastatic liver malignancies. However, they are considered to be relatively contraindicated for tumors in high-risk locations due to technical difficulties and a perceived increased risk of perioperative complications. Several techniques, including artificial ascites, non-touch multibipolar ablation, and laparoscopically assisted ablation, can be used to improve the outcomes of ablation for high-risk tumors. This review aims to provide a comprehensive summary of the techniques currently used to improve thermal ablation outcomes for high-risk liver tumors.
