目的　应用离体猪肝构建简单、经济、能模拟出血和胆漏的腹腔镜肝切除术培训模型，并对培训模型进行评价。  方法　将新鲜的保留肝门和小段肝后下腔静脉的猪肝放置在组装的腹腔镜培训装置中，用红色明胶液体灌注肝静脉、门静脉、肝动脉以模拟肝脏血流，黄色明胶液体灌注胆总管模拟肝脏胆汁。首先由3名腹腔镜专家对此模型进行各种方式的肝切除操作并提出改进意见，结合专家意见，对模型进行改进。其次，由6名具有腹腔镜经验的肝胆外科医生对最终模型进行肝切除操作，用5分量表对最终模型的解剖结构、质地、血流情况等指标进行评分。  结果　与真实手术环境相比，对最终模型解剖结构的评分是4.6±0.3，质地的评分是4.9±0.1，血流情况评分是4.7±0.3, 胆漏情况评分是4.6±0.2。  结论　此培训模型构建简单、经济、能较真实的模拟术中出血、胆漏，可以用于腹腔镜肝切除术的高级培训。

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.
