Area of Science:

  • Surgical Oncology
  • Vascular Surgery
  • Gastroenterology

Background:

  • Portal occlusion previously limited surgical interventions for portal vein or hepatic artery procedures.
  • Complex peripancreatic arterial anatomy posed challenges for isolated pancreatoduodenectomy.
  • The non-touch isolation technique requires precise dissection and margin assessment.

Purpose of the Study:

  • To introduce an established isolated pancreatoduodenectomy technique for pancreatic head cancer.
  • To detail the development and application of an antithrombogenic bypass catheter.
  • To describe the mesenteric approach for improved surgical and oncological outcomes.

Main Methods:

  • Development of an antithrombogenic bypass catheter for portal system procedures (1981).
  • Implementation of non-touch isolation techniques for pancreatoduodenectomy.
  • Establishment of a mesenteric approach for pancreatoduodenectomy (1992), including systematic lymphadenectomy and mesopancreas excision.

Main Results:

  • The antithrombogenic catheter-bypass procedure overcame time limitations from portal occlusion.
  • The mesenteric approach facilitated dissection, ensured cancer-free margins, and enabled complete mesopancreas excision.
  • Isolated pancreatoduodenectomy, combining these advancements, was finalized in 1992.

Conclusions:

  • The developed antithrombogenic catheter-bypass and mesenteric approach established an ideal surgical and oncological procedure for pancreatic head cancer.
  • This technique offers safe and effective resection and reconstruction of the portal vein and hepatic artery.
  • The precise surgical techniques are presented for broader clinical application.
