The Efficacy and Safety of a Microwave Ablation System with a Dipole Antenna Design Featuring Floating Sleeves and Anti-Phase Technology in Stereotactic Percutaneous Liver Tumor Ablation: Results from a Prospective Study.

Simple Summary: Percutaneous microwave ablation (MWA) is a key treatment for primary and secondary liver malignancies. The aim of this prospective study was to evaluate the efficacy and safety of the Surgnova Dophi™ M150E MWA system and to compare ablation defect characteristics with data from the manufacturer's ablation charts, as well as findings from the literature. In a cohort of 50 patients with 77 liver tumors, stereotactic CT-guided MWA was applied using this novel technology. A primary technique efficacy of 97.4% was achieved, with complete ablation in 75 out of 77 tumors. Complications occurred in 10% of patients, with only 4% classified as major. A comparison with previous in vivo data confirmed the reliability of the system in achieving reproducible and predictable ablation results. In conclusion, the Surgnova Dophi™ M150E system has an excellent efficacy and safety profile for percutaneous stereotactic liver tumor treatment, highlighting its potential in the growing field of interventional oncology. Purpose: To evaluate the efficacy and safety of the Surgnova Dophi™ M150E microwave ablation system in a prospective single-center observational study. Methods: A cohort of 50 patients with 77 primary or secondary liver tumors underwent CT-navigated stereotactic percutaneous microwave ablation with curative intention using the Surgnova Dophi™ M150E system. The endpoints were primary technique efficacy (PTE), number of complications, ablation defect dimensions, and sphericity index compared to previously reported findings. Results: The PTE was 97.4%, with complete ablation in 75 out of 77 tumors. Complications occurred in 10% of patients, with 4% classified as major. A comparison with previous in vivo data confirmed the reliability of the system in achieving reproducible and predictable ablation results. Conclusions: Stereotactic percutaneous microwave ablation with the Surgnova Dophi™ M150E system is safe and effective for liver tumor treatment. [ABSTRACT FROM AUTHOR]
