目的： 探究用新鲜冰冻尸体进行腹腔镜减重代谢手术的教学效果。方法： 2018年12月至2019年12月,用新鲜冰冻尸体开展3次腹腔镜减重代谢手术学习班。对学员发放问卷,统计教学前、后知识掌握程度及课程评价。结果： 参加第3次培训13名学员的减重代谢手术相关知识问卷结果显示,培训前平均（6.15±1.51）分,培训后平均（8.08±1.20）分,分数前、后差异有统计学意义（P<0.05）。参加前2次培训22名学员的教学反馈问卷调查中,16名（72.7%）认为新鲜冰冻尸体教学有助于提高对术中解剖结构的认识,19名（86.4%）认为有利于培训后新开展减重代谢手术,13名（59.1%）拟培训后新开展减重代谢手术。结论： 新鲜冰冻尸体行腹腔镜减重代谢手术教学切实可行,有利于减重代谢手术的规范化发展。

Objective To explore the effect of fresh frozen cadavers on training of laparoscopic metabolic and bariatric surgery (LMBS). Methods From December 2018 to December 2019, three training courses of LMBS were conducted using fresh frozen cadavers. Participants were given questionnaires to test the knowledge before and after the trai-ning courses and to evaluate the courses. Results Thirteen participants in the third training course provided feedback of questionnaires and showed the scores (6.15±1.51) points before training course and (8.08±1.20) points after training course with significant difference (P<0.05). The feedback of questionnaire was obtained from 22 participants who attended first or second training course, of whom 16 (72.7%) believed that training courses on fresh frozen cadavers was positive for their understanding of intraoperative anatomy, 19 (86.4%) valued the course in carrying out of LMBS, and 13 (59.1%) proposed to carry out LMBS after training. Conclusions The training courses of LMBS on fresh frozen cadavers are feasible and of value in improvement of participants knowledge and development of LMBS.
