This study introduces a novel 3D-printed hybrid simulator for laparoscopic choledochal surgery, offering realistic tactile feedback for complex procedures. The simulation was well-received by trainees, demonstrating its potential for surgical skills acquisition.

Area of Science:

  • Surgical Simulation
  • Medical Device Technology
  • 3D Printing Applications

Background:

  • Realistic nonbiological simulators for complex reconstructive surgery, particularly those offering tactile feedback, are scarce.
  • Technological advancements are needed to address shortages in surgical training models.
  • Laparoscopic simulation has significantly improved skills acquisition for many surgical procedures.

Purpose of the Study:

  • To describe a novel hybrid model for laparoscopic choledochal surgery simulation using 3D technology.
  • To evaluate the feasibility and user feedback of a 3D-printed laparoscopic choledochal surgery simulator.
  • To explore the potential of 3D printing in creating realistic simulators for complex and rare surgical operations.

Main Methods:

  • A laparoscopic choledochal surgery model was created using digital hepatic anatomy images and standard laparoscopic trainer dimensions.

  • A 3D Systems Project 660Pro printer and specialized materials were used to fabricate a liver mold with integrated components for ducts and cysts.
  • Soft silicone replicas were produced from the mold, and the model was assessed by delegates at a national pediatric surgery training day.

    • Main Results:

    • Delegates rated the simulator's tactile likeness positively (5.6/10) and found it to be of appropriate complexity (6.2/10) and very useful (7.36/10).
    • 100% of participants felt the simulation could be reproduced in their own centers.
    • 100% of participants would recommend this simulation to colleagues.

    Conclusions:

    • 3D printing offers a viable method for developing specific and detailed surgical simulations for rare and complex operations.
    • This initial phase of a choledochal cyst excision simulation shows significant potential for further development.
    • The developed hybrid model demonstrates promise in enhancing surgical training for complex laparoscopic procedures.
