Breakthrough in Laparoscopic Liver Surgery: Novel Haemostasis Method Developed

Strategic Insights -

Researchers at the Beijing Institute of Technology have made significant progress in laparoscopic liver surgery, developing a novel haemostasis method to control bleeding during liver resection surgeries. The team, led by Prof. Benzhu Guo, has designed an artificial liver blood vessel made of silicone rubber, wrapped by artificial connective tissues made of rubbery sponges. This innovative design allows for accurate and quantitative haemostasis, addressing the limitations of the traditional Pringle manoeuvre. The new method has been successfully tested in live pigs, demonstrating its effectiveness in controlling bleeding from hepatic vessels.

Key Takeaways:

  • Researchers at Beijing Institute of Technology have developed a novel haemostasis method for controlling bleeding during laparoscopic liver surgery.
