Aim:
Laparoscopic pancreaticojejunostomy is among the most difficult and high-risk operations. Surgeons with low or moderate seniority rarely are allowed to perform this surgery in clinics. Therefore, there is an urgent need to develop a reliable simulation training model focused on laparoscopic pancreaticojejunostomy and an effective stepwise training program.
Methods:
Surgeons with different working experiences or exposure to different training programs at Sir Run Run Shaw Hospital were divided into four groups. Each was required to perform laparoscopic pancreaticojejunostomy using a designed three-dimensional dry lab model. All surgeons' baseline characteristics and surgical performance, including operation time and score, were recorded and analysed. The authenticity of the model was evaluated by four senior surgeons.
Results:
The surgeon group with higher seniority had an older average age, longer working time, and had completed more laparoscopic cholecystectomy and laparoscopic common bile duct exploration procedures. Meanwhile, the surgeon group with higher seniority presented better operation performance, including shorter operation time and higher operation score in their initial simulation training. Resident surgeons who underwent stepwise training with the laparoscopic biliary-enteric anastomosis training program showed better initial performance than resident surgeons who underwent stepwise training with the laparoscopic basic suture training program. After repeated training, the surgeons showed improved surgical performance.
Conclusion:
Our pancreaticojejunostomy model showed a good degree of discernibility, as surgeons with more experience performed better with the model for their initial simulation training in laparoscopic pancreaticojejunostomy. Stepwise training of the laparoscopic biliary-enteric anastomosis training program helped surgeons obtain a better initial performance, and repeated simulation training on this model improved the surgeon's operative performance.
