Summary
To determine safety, ablative zone, technical success rate and early safety data of recently introduced cool-wet electrode in eligible patients who are indicative for radiofrequency ablation (RFA) for liver tumors.
Detailed description
To determine safety, ablative zone, technical success rate and early safety data (12 months local tumor progression rate) of recently introduced cooled-wet electrode in eligible patients who are indicative for radiofrequency ablation (RFA) for liver tumors in comparison with currently used separable clustered electrode in our institution. Owing to tissue cooling effect of internally cooled-wet electrode can be used in switching bipolar mode. Patients would be randomized into two groups (cool-wet electrode group and separable clustered electrode in switching monopolar mode). The results from this preliminary study would be used for main study to compare the efficacy and safety data between two electrodes in the future.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| DEVICE | cooled-wet electrode | RFA is performed using three cooled-wet electrodes in switching bipolar mode. The electrode is anticipated to reduce tissue resistance by releasing small amount of saline during the procedure, which may lead larger ablative volume by delivering more RF energy. |
| DEVICE | separable clustered electrode | RFA is performed using separable clustered electrode in switching monopolar mode. |
