The VIO soft-coagulation system (SCS) effectively reduces surgical time and blood loss during liver resections compared to conventional methods. This innovative device offers a safe alternative without increasing postoperative complications.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Technology
  • Minimally Invasive Procedures

Background:

  • The VIO soft-coagulation system (SCS) is a novel device for tissue coagulation.
  • Its efficacy in liver resection procedures requires evaluation.

Purpose of the Study:

  • To assess the effectiveness of the SCS in liver resection.
  • To compare SCS with conventional methods for hemostasis and transection.

Main Methods:

  • A comparative study involving 252 patients undergoing liver resection.
  • Patients were divided into two groups: conventional (ultrasonic dissector and bipolar electrocautery) and SCS group (SCS used for hemostasis).

Main Results:

  • The SCS group demonstrated significantly reduced median blood loss (350 vs 640 mL) and surgical time (280 vs 398 min).

  • No significant differences in postoperative complications were observed between groups.
  • SCS use was associated with decreased bleeding and surgical time in specific subgroups, including major hepatectomy.

    • Conclusions:

    • The SCS is a safe and effective tool for liver resection.
    • It significantly decreases surgical time and bleeding without increasing complications like bile leakage.
