This study presents a novel teaching model for laparoscopic choledochojejunostomy. The model effectively trains surgeons in advanced laparoscopic suturing techniques and demonstrates the procedure

Area of Science:

  • Surgical Education
  • Minimally Invasive Surgery
  • Gastrointestinal Surgery

Background:

  • Advanced laparoscopic procedures require specialized skills, including suturing.
  • Effective teaching models are crucial for surgeons to gain proficiency in new laparoscopic techniques.
  • Laparoscopic choledochojejunostomy is an advanced procedure demanding rigorous training.

Purpose of the Study:

  • To outline the technical difficulties and operative steps of a laparoscopic choledochojejunostomy and drainage via Roux-en-Y-loop.
  • To present a novel animal model for teaching advanced laparoscopic suture techniques.
  • To assess the feasibility and functionality of the described laparoscopic procedure.

Main Methods:

  • Eight pigs (approx. 35 kg) underwent laparoscopic choledochojejunostomy.

  • Procedure steps and technical challenges were documented.
  • Bypass functionality was assessed via bilirubin monitoring and contrast injection post-4-month follow-up.

    • Main Results:

    • The model provided excellent conditions for teaching laparoscopic suture techniques.
    • Laparoscopic choledochojejunostomy was demonstrated as feasible within a mean operative time of 122 minutes.
    • Post-necropsy measurements confirmed the patency and functionality of the created bypass.

    Conclusions:

    • This animal model is highly suitable for training surgeons in advanced laparoscopic suturing for choledochojejunostomy.
    • The presented technique for laparoscopic choledochojejunostomy is feasible and can be performed within a reasonable timeframe.
    • The model facilitates the acquisition of confidence and skills necessary for complex laparoscopic gastrointestinal surgery.
