Summary

Water-jet dissection is effective for cutting fatty tissue, preserving vessels at 30-40 Bar. Higher pressures increase damage risk without deeper cuts, requiring in vivo study for human application.

Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Plastic Surgery

Background:

  • Water-jet dissection, first reported in 1982, offers advantages over conventional cutting by preserving vessels and nerves.
  • Newer water-jet devices are used in liver surgery to minimize blood loss.
  • Investigating water-jet dissectors for other surgical fields, particularly for vessel preparation in fatty tissue for plastic surgery, is ongoing.

Purpose of the Study:

  • To optimize the technical parameters of water-jet dissection for preparing vessels in fatty tissue.
  • To determine the optimal pressure and application parameters for effective and safe water-jet dissection in adipose tissue.

Main Methods:

  • Abdominal fat tissue from fresh cadavers was dissected using a water-jet device under standardized conditions.

  • Various cutting pressures and application passes were tested.
  • Cut depth and the morphological integrity of blood vessels were analyzed.

    • Main Results:

    • Cuts of 8 mm depth were achieved with 20-60 Bar pressure in a single pass.
    • Repeated passes increased cutting depth; 5 passes at 40 Bar resulted in 1.7 cm cuts.
    • Vessels remained morphologically undamaged at pressures not exceeding 40 Bar, with minimal water uptake in the tissue.

    Conclusions:

    • Optimal pressure for water-jet dissection in fatty tissue is between 30 and 40 Bar.
    • Pressures above 40 Bar do not increase cutting depth but elevate the risk of vessel damage.
    • Further in vivo studies are necessary to evaluate the mechanical effects on vessels before human application, especially for flap dissection.
