The validity of the CALMA Veterinary Lap-trainer simulator (CVLTS) for training basic veterinary laparoscopic skills was assessed and compared to a simple collapsible mobile box trainer. Ten veterinarian surgeons with no experience in laparoscopic surgery and four experts with at least two years of experience in minimally invasive surgery (MIS) were included. The training curriculum included object transfer, non-woven gauze cutting with curved scissors, and interrupted and continuous intracorporeal sutures, which were practiced on the CVLTS. The initial and final assessments were carried out in both the CVLTS and in a collapsible mobile simulator. These were video-recorded and evaluated by external experts using the Objective Structured Assessment of Technical Skills (OSATS) and a specific scale evaluation in a double-blinded schedule. The time, angular displacement, number, and movement smoothness were recorded using a hands movement assessment system (HMAS). Through a survey, the face validity and content were evaluated. The data were analyzed by a Pearson's proportions comparison or Mann Whitney U test and a bilateral Student's -test. The experimental group OSATS, specific scores, and HMAS values, with the exception of the smoothness of movements, significantly improved after training, with no statistically significant differences compared to the expert group. No differences were found between the two simulators. The experts' and experimental participants' CVLTS mean score was 4.8. Our data support the CVLTS validations for laparoscopic surgery basic skills training.
评估了CALMA兽医腹腔镜训练模拟器（CVLTS）在训练基本兽医腹腔镜技能方面的有效性，并与一个简单的可折叠移动箱式训练器进行了比较。纳入了10名没有腹腔镜手术经验的兽医外科医生和4名至少有两年微创手术（MIS）经验的专家。训练课程包括物体转移、用弯剪刀切割无纺布纱布以及间断和连续体内缝合，这些操作在CVLTS上进行练习。在CVLTS和可折叠移动模拟器上都进行了初始和最终评估。这些评估进行了视频记录，并由外部专家使用客观结构化技能评估（OSATS）和特定的量表评估，采用双盲方案。使用手部动作评估系统（HMAS）记录时间、角位移、数量和动作流畅度。通过一项调查，对面部效度和内容进行了评估。数据通过Pearson比例比较或Mann Whitney U检验以及双侧Student检验进行分析。实验组的OSATS、特定分数和HMAS值，除动作流畅度外，训练后有显著改善，与专家组相比无统计学显著差异。两个模拟器之间未发现差异。专家和实验参与者的CVLTS平均得分是4.8。我们的数据支持CVLTS在腹腔镜手术基本技能训练方面的有效性验证。
