The present study was designed to investigate whether there is a correlation between manual skills in laparoscopic procedures and manual skills in flexible endoscopy.
In a prospective study using laparoscopy and endoscopy simulators (MIST-VR, and GI-Mentor II), 24 consecutive subjects (gastrointestinal surgeons, novice and experienced gastroenterologists, and untrained subjects) were asked to perform laparoscopic and endoscopic tasks. Their performance was assessed by the simulators' software and by observers blinded to the levels of subjects' experience. Performance in experienced vs inexperienced subjects was compared. Score pairs of three parameters--time, errors, and economy of movement--were also compared.
Experienced subjects performed significantly better than inexperienced subjects on both tasks in terms of time, errors, and economy of movement (p < 0.05). All three performance parameters in laparoscopy and endoscopy correlated significantly (p < 0.02).
Both simulators can distinguish between experienced and inexperienced subjects. Observed skills in simulated laparoscopy correlate with skills in simulated flexible endoscopy. This finding may have an impact on the design of training programs involving both procedures.
本研究旨在调查腹腔镜手术操作技能与软性内镜操作技能之间是否存在相关性。
在一项使用腹腔镜和内镜模拟器（MIST-VR和GI-Mentor II）的前瞻性研究中，连续24名受试者（胃肠外科医生、新手和经验丰富的胃肠病学家以及未经培训的受试者）被要求进行腹腔镜和内镜任务。他们的表现由模拟器软件和对受试者经验水平不知情的观察者进行评估。比较了有经验和无经验受试者的表现。还比较了时间、错误和动作经济性这三个参数的得分对。
在时间、错误和动作经济性方面，有经验的受试者在两项任务上的表现均显著优于无经验的受试者（p<0.05）。腹腔镜检查和内镜检查的所有三个性能参数均显著相关（p<0.02）。
两种模拟器都能区分有经验和无经验的受试者。观察到的模拟腹腔镜检查技能与模拟软性内镜检查技能相关。这一发现可能会对涉及这两种操作的培训计划设计产生影响。
