Summary

Open radiofrequency (RF) ablation is a safe and effective technique for treating liver tumors, especially in patients at risk of bleeding. This method allows for transfusion-free resection, reducing complications and improving patient outcomes.

Area of Science:

  • Hepatobiliary Surgery
  • Interventional Radiology
  • Oncology

Context:

  • Radiofrequency (RF) ablation is a minimally invasive treatment for hepatic neoplasms.
  • Surgical approaches include percutaneous, laparoscopic, and open methods.
  • Open RF (ORF) offers specific advantages in certain clinical scenarios.

Purpose:

  • To detail the role and outcomes of open radiofrequency ablation (ORF) for hepatic neoplasms.
  • To evaluate the feasibility and safety of ORF in liver tumor treatment.

Summary:

  • A study involving 13 open RF ablations (ORFs) for hepatic neoplasms between November 2002 and November 2003.
  • Intraoperative ultrasonography identified additional lesions in 7.7% of cases.
  • RF energy created zones of necrosis along tumor margins prior to surgical resection, with an average operating time of 74.4 minutes and mean blood loss of 104 mL.

Impact:

  • ORF is suitable for patients at risk of bleeding, enabling transfusion-free resections.
  • The technique is associated with reduced postoperative complications and shorter hospital stays (average 7.9 days).
  • No mortality or liver recurrence was observed during a mean 6-month follow-up, though longer-term evaluation is needed.
