Area of Science:

  • Hepatobiliary surgery
  • Surgical oncology
  • Medical imaging

Background:

  • Surgical treatment of liver malignancies is vital for curative intent and survival.
  • Achieving accurate resection margins is critical for long-term patient outcomes.
  • Conventional liver surgery can be challenging, especially for complex or centrally located tumors.

Purpose of the Study:

  • To evaluate the effectiveness of 3D ultrasound-based navigational systems in liver malignancy resection.
  • To compare the outcomes of navigational resection with conventional liver surgery.
  • To assess the impact of 3D modeling and navigational systems on achieving tumor-free margins and preserving liver tissue.

Main Methods:

  • Application of navigational systems with repetitive data registration.
  • Generation of preoperative three-dimensional (3D) models for surgical planning.
  • Utilizing a 3D ultrasound-based technique for intraoperative visualization and orientation.

Main Results:

  • Navigational systems increased the rate of resections with tumor-free margins.
  • 3D ultrasound-based technique provided optimal visualization and orientation during surgery.
  • The navigational approach led to more accurate resections compared to conventional methods.

Conclusions:

  • 3D ultrasound-based navigational resection is effective for liver malignancies.
  • This technique improves surgical precision, leading to better resection margins and tissue preservation.
  • Navigational surgery enhances outcomes for liver cancer treatment in daily routine.
