Vascular surgical techniques improve the removal of liver, biliary, and pancreatic cancers by reconstructing veins and preserving organ circulation. Further research is needed to confirm long-term survival benefits.

Area of Science:

  • Surgical Oncology
  • Vascular Surgery
  • Hepatobiliary and Pancreatic Surgery

Background:

  • Malignancies of the liver, biliary tract, and pancreas often involve major vasculature, complicating surgical resection.
  • Radical resection is crucial for potentially curative treatment of these cancers.
  • Preservation of organ circulation during tumor resection is vital for patient outcomes.

Purpose of the Study:

  • To evaluate the application and outcomes of vascular surgical techniques in radical resection of abdominal malignancies.
  • To assess the feasibility of portal vein and hepatic vein reconstruction in liver, biliary, and pancreatic cancer surgery.
  • To determine the role of vascular reconstruction in improving resectability and preserving organ function.

Main Methods:

  • Application of vascular surgical techniques including portal vein reconstruction (distal and proximal) in 32 patients.

  • Resection and reconstruction of tumor-involved hepatic vein trunks in six patients.
  • Prosthetic graft replacement of the suprarenal inferior vena cava in three patients with retroperitoneal malignancy.

    • Main Results:

    • Vascular reconstruction techniques were successfully applied in patients with advanced liver, biliary, and pancreatic cancers.
    • Portal vein reconstruction was performed in 16 patients with pancreatic cancer and 16 with liver/biliary tract cancer.
    • Hepatic vein and inferior vena cava reconstruction demonstrated the feasibility of managing complex vascular involvement.

    Conclusions:

    • Vascular surgical techniques enhance the resectability of malignant tumors in the liver, biliary tract, and pancreas.
    • These techniques help preserve circulation in the remaining organ, potentially improving post-operative function.
    • Wider application of vascular surgery in general abdominal surgery is recommended for complex oncological resections.
