先进的医疗模拟器已被引入，以促进手术和内窥镜培训，从而提高病人的安全。在Procedicus微创手术培训器-虚拟现实（MIST-VR）腹腔镜模拟器中接受培训的住院医生比对照组更安全、更快地进行腹腔镜胆囊切除术。关于性别、计算机经验和视觉空间测试等因素是否可以预测医疗模拟器的性能，很少有报道。我们的目的是调查这些因素是否影响模拟胃镜检查的性能。17名医学生被问及电脑游戏体验。在虚拟内窥镜检查之前，他们进行了视觉空间测试PicCOr，该测试区分了受试者从二维呈现中创建三维图像的能力。每名学生在GI Mentor II，Simbionix中进行一次胃镜检查（1级，病例1），并记录了与性能相关的几个变量。在内窥镜中清晰视野所花费的时间百分比与PicSOr测试的性能相关性良好（r = 0.56，P < 0.001）。筛选效率与PicSOr相关（r = 0.23，P < 0.05）。在有电脑游戏经验的学生中，筛查效率增加（33.6% +/- 3.1%对22.6% +/-2.8%，P < 0.05），检查时间减少1.5分钟（P < 0.05）。与妇女相比，男子也有类似的趋势。视觉空间测试PicSOr可预测内窥镜模拟器GI Mentor II的结果。二维图像体验，如在电脑游戏中，似乎也会影响结果。(C)2004年，消化道外科学会。
Advanced medical simulators have been introduced to facilitate surgical and endoscopic training and thereby improve patient safety. Residents trained in the Procedicus Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) laparoscopic simulator perform laparoscopic cholecystectomy safer and faster than a control group. Little has been reported regarding whether factors like gender, computer experience, and visuospatial tests can predict the performance with a medical simulator. Our aim was to investigate whether such factors influence the performance of simulated gastroscopy. Seventeen medical students were asked about computer gaming experiences. Before virtual endoscopy, they performed the visuospatial test PicCOr, which discriminates the ability of the tested person to create a three-dimensional image from a two-dimensional presentation. Each student performed one gastroscopy (level 1, case 1) in the GI Mentor II, Simbionix, and several variables related to performance were registered. Percentage of time spent with a clear view in the endoscope correlated well with the performance on the PicSOr test (r = 0.56, P < 0.001). Efficiency of screening also correlated with PicSOr (r = 0.23, P < 0.05). In students with computer gaming experience, the efficiency of screening increased (33.6% +/- 3.1% versus 22.6% +/- 2.8%, P < 0.05) and the duration of the examination decreased by 1.5 minutes (P < 0.05). A similar trend was seen in men compared with women. The visuospatial test PicSOr predicts the results with the endoscopic simulator GI Mentor II. Two-dimensional image experience, as in computer games, also seems to affect the outcome. (C) 2004 The Society for Surgery of the Alimentary Tract.
