Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics
  • Gastrointestinal Surgery

Background:

  • Robotically assisted laparoscopy is being evaluated for complex biliary reconstructive procedures.
  • The Roux-en-Y hepaticojejunostomy is a critical surgical technique in managing biliary disorders.
  • Comparing robotic, laparoscopic, and open approaches is essential for surgical innovation.

Purpose of the Study:

  • To assess the feasibility and safety of robotically assisted laparoscopic Roux-en-Y hepaticojejunostomy.
  • To compare the robotic approach with open and standard laparoscopic methods.
  • To evaluate operative times, techniques, and complication rates across different surgical modalities.

Main Methods:

  • A jaundice model was created in 18 pigs via needlescopic common bile duct ligation.

  • Pigs were randomly assigned to open, standard laparoscopy, or robotically assisted laparoscopy (Zeus) groups (n=6 each).
  • Operative metrics including time, technique, and complications were meticulously documented by a single surgeon.

    • Main Results:

    • The open approach was the fastest overall.
    • No significant differences in total stitches were observed for the hepaticojejunostomy.
    • The robotic approach required fewer stitches and less time for the posterior wall of the hepaticojejunostomy (P<0.05).
    • Hepaticojejunostomy operative time was comparable between standard laparoscopy and robotic assistance.

    Conclusions:

    • Robotically assisted laparoscopic Roux-en-Y hepaticojejunostomy is a viable and safe surgical option.
    • The operating time for the robotic approach is similar to standard laparoscopy.
    • This technique offers potential benefits in precision for specific aspects of the reconstruction.
