Abstract

Purpose

To investigate the learning curve in four basic surgical skills in laparoscopic and robotic surgeries, and evaluate the approximate time needed to reach sufficient expertise in performing these tasks with the avatera® system.

Methods

Twenty urology residents with no previous experience in dry-lab and robotic surgery were asked to complete four basic laparoscopic tasks (peg transfer, circle cutting, needle guidance, and suturing) laparoscopically and robotically. All participants were asked to complete the tasks first after watching the Uroweb educational material and, second, after undertaking a 2-hour training in robotic and laparoscopic dry-lab. Thereafter, all trainees continued to undertake 2-hour training programs until being able to complete the tasks with the avatera® robot at the desired time. Paired t test and one-way ANOVA test were used to analyze time differences between the groups.

Results

Time needed to complete all tasks either robotically or laparoscopically was significantly less in the second compared to the first attempt for all Groups in each Task. In the robotic dry-lab, time needed to complete the tasks was significantly less than in the laparoscopic dry-lab. A significant effect of previous laparoscopic experience of the participants on the training time needed to achieve most of the goal times was detected.

Conclusion

The results of the study highlight the role of previous laparoscopic experience in the training time needed to achieve the performance time goals and demonstrate that the learning curve of basic surgical skills using the avatera® system is steeper than the laparoscopic one.

我们需要多长时间才能获得足够的 Avatera® 机器人系统专业知识？

摘要

目的

研究腹腔镜和机器人手术中四种基本手术技能的学习曲线，并评估使用 avatera® 系统执行这些任务时达到足够专业知识所需的大致时间。

方法

二十名没有干实验室和机器人手术经验的泌尿科住院医师被要求通过腹腔镜和机器人完成四项基本腹腔镜任务（钉转移、切圈、针引导和缝合）。所有参与者都被要求首先在观看 Uroweb 教育材料后完成任务，其次在机器人和腹腔镜干实验室接受 2 小时的培训。此后，所有学员继续进行2小时的培训计划，直到能够在期望的时间使用avatera®机器人完成任务。采用配对t检验和单因素方差分析来分析组间的时间差异。

结果

与每个任务中所有组的第一次尝试相比，第二次通过机器人或腹腔镜完成所有任务所需的时间明显减少。在机器人干燥实验室中，完成任务所需的时间明显少于腹腔镜干燥实验室。检测到参与者之前的腹腔镜经验对实现大部分目标时间所需的训练时间有显着影响。

结论

研究结果强调了以前的腹腔镜经验在实现执行时间目标所需的培训时间中的作用，并证明使用 Avatera® 系统的基本手术技能的学习曲线比腹腔镜的学习曲线更陡。
