Objective To construct and assess a simple, economical training model for laparoscopic liver resection(LLR) in a simulated continuous blood supply setting. Methods A fresh porcine liver was placed in a specific laparoscopic training device and the vessels were infused with red-dyed liquid gelatin to simulate the blood supply of the liver and with yellow-dyed liquid gelatin for respresentation of the bile ducts. A total of 3 liver surgical experts tried the initial model, whose impression of the prototype was collected to improve the model for future use. Then a final model were developed and used for practicing laparoscopic liver resection by 6 hepatobiliary surgeons with laparoscopic experience. Data were collected using anonymous questionnaires with a Likert scale (1=strongly disagree; 2=disagree; 3=neither agree nor disagree; 4=agree; 5=strongly agree). Feedbacks on the ex-vivo model were obtained regarding the realism of the anatomical condition of the model, operative tactile properties, and the realism of the simulated blood supply during the resection. Results Compared with the real operative conditions, quality assessment of the model for anatomical condition was 4.6±0.3, for operative tactile was 4.9±0.1, for blood supply was 4.7±0.3，and for bile leak was 4.6±0.2. Conclusion The model is simple and economical. It can offer the trainees the opportunities to learn advanced skills necessary for LLH in simulated blood supply condition.
