Robot-assisted laparoscopic surgery for biliary obstruction proved safe and effective in pigs. This advanced technique offers a viable alternative for complex reconstructions, demonstrating feasibility within acceptable timeframes.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Robotics
  • Gastroenterology

Background:

  • Laparoscopic choledochojejunostomy and Roux-en-Y reconstruction present technical challenges for biliodigestive anastomosis.
  • Robotic systems offer enhanced dexterity and vision for complex laparoscopic procedures.
  • Endoscopic stenting is standard palliative care for biliary obstruction from periampullary tumors.

Purpose of the Study:

  • To evaluate the efficacy and safety of robot-assisted laparoscopic choledochojejunostomy and Roux-en-Y reconstruction.
  • To compare robotic-assisted laparoscopic approach with traditional laparotomy.

Main Methods:

  • Ten pigs underwent robot-assisted laparoscopic procedures using the da Vinci system.
  • Ten pigs underwent traditional laparotomy procedures as controls.

  • Key metrics included operating room time, anastomosis time, blood loss, and complications. Anastomosis patency was assessed post-procedure.

    • Main Results:

    • Robot-assisted procedures had significantly longer operating room times (140 vs. 82 min).
    • Blood loss was minimal (<10 cc) in the robot-assisted group versus controls (30 cc).
    • All anastomoses were patent and functional in both groups; complication rates were comparable.

    Conclusions:

    • Robot-assisted laparoscopic choledochojejunostomy is a safe and effective procedure.
    • The technique is feasible for complex biliodigestive reconstruction.
    • The procedure can be completed within an acceptable time frame.
