Safety, efficacy and rapidity in new surgical resection procedures

Multi-electrode radiofrequency ablation surgery is a safe method to treat liver cancer patients, this method can be completed in less time than part removal techniques. Currently, according to a new study by researchers at the University of Wisconsin in Madison.

Dr. Paul Laeseke, the leader of the research team, said: 'One of the biggest limitations of the recent radiofrequency ablation is that there is no effective treatment for large tumors.' The current radiofrequency surgical system can only provide electricity for one electrode and create a small removal area, large tumors are treated by cutting the knee to small areas - a technique that is both complex and time-consuming.

The study involved 38 malignant liver tumors in 23 patients who underwent multi-electrode radiofrequency resection surgery. Local control achieved 37/38 tumors, of which 34 tumors were treated for only 1 session. Total surgery time decreased by about 54% compared to patients treated with monopolar system.

Dr. Laeseke said: 'Cutting the time in the surgical procedure helps the team and the equipment to be ready for other cases. The rate of successful treatment in this study was compared with those in the literature for treating small tumors with monopolar radioactivity, " he continued: " In other words, the multipolar system allowing us to effectively treat large tumors in less time '.

Dr. Laeseke notes: These are short-term results. While these short-term results are promising and demonstrate safe and effective multi-electrode radiofrequency ablation, further long-term follow-up studies are needed to determine the impact of the method. ablation by multi-electrode radiation frequency on patient survival and tumor recurrence rate.

The full results of this study were published in the June issue of the American Journal of Roentgenology , published by the American Roentgen Ray Society (American X-ray Association).
