Area of Science:

  • Hepatobiliary surgery
  • Minimally invasive surgery
  • Surgical oncology

Context:

  • Laparoscopic liver resections are increasingly adopted due to benefits like faster recovery and improved cosmesis.
  • Hepatocellular carcinoma (HCC) presents surgical challenges, especially in cirrhotic patients.
  • Intraoperative bleeding is a significant concern in laparoscopic liver surgery.

Purpose:

  • To report the first successful use of a laparoscopic radiofrequency device in Brazil for hepatocellular carcinoma resection.
  • To evaluate the feasibility and outcomes of this technique in cirrhotic patients.

Summary:

  • The study details the successful application of a laparoscopic radiofrequency device for segment VI hepatocellular carcinoma resection in two cirrhotic patients.
  • Hepatic vascular exclusion was not required, and no blood transfusions were necessary during the procedures.

  • Both patients experienced a short hospital stay, being discharged on the fourth postoperative day.

    • Impact:

    • Demonstrates the potential of laparoscopic radiofrequency devices as a safe and effective tool for HCC resection in cirrhotic liver disease.
    • Highlights the possibility of achieving radical tumor removal with minimal blood loss and reduced patient recovery time.
    • Establishes a precedent for the adoption of advanced laparoscopic techniques in liver surgery within Brazil.
