To prevent unnecessary mistakes and avoidable complications in laparoscopic surgery, there has to be proper training. A safe way to train surgeons for laparoscopy is simulation. This study addresses the face validity of ProMIS, an Augmented Reality laparoscopic simulator, as a tool for training suturing skills in laparoscopic surgery. A two-paged, 12-item structured questionnaire, using a five-point-Likert scale, was presented to 50 surgeons/surgical interns. The participants were allotted to two groups: an "expert" (>50 procedures; N=23) and a referent group (<50 procedures; N=27). Non-parametric statistics were used to determine statistical differences. General consensus existed in both expert and referent groups, delineating ProMIS as a useful tool in teaching suturing skills surgeons/surgical interns (mean + or - st dev, resp, score 4.91 + or - 0.42 and 4.93 + or - 0.38) with regard to realism, tactile feedback, and suturing techniques. Significant differences in opinion regarding the ergonomics and design of ProMIS between the expert and referent groups existed. The ProMIS Augmented Reality laparoscopic simulator is regarded as a useful tool in laparoscopic training in both expert and referent groups. Although significant differences in opinion existed with regards to ergonomics and design of ProMIS, they were present between experts and novices.
为防止腹腔镜手术中出现不必要的错误和可避免的并发症，必须进行适当的培训。一种培训外科医生进行腹腔镜手术的安全方法是模拟。本研究探讨了增强现实腹腔镜模拟器ProMIS作为腹腔镜手术缝合技能培训工具的表面效度。向50名外科医生/外科实习生发放了一份两页、12项的结构化问卷，采用五点李克特量表。参与者被分为两组：“专家”组（>50例手术；N=23）和参照组（<50例手术；N=27）。采用非参数统计来确定统计学差异。专家组和参照组普遍认为，在逼真度、触觉反馈和缝合技术方面，ProMIS是培训外科医生/外科实习生缝合技能的有用工具（平均±标准差，分别为4.91±0.42和4.93±0.38）。专家组和参照组在ProMIS的人体工程学和设计方面的意见存在显著差异。ProMIS增强现实腹腔镜模拟器在专家组和参照组的腹腔镜培训中均被视为有用工具。尽管在ProMIS的人体工程学和设计方面存在显著的意见差异，但这些差异存在于专家和新手之间。
