The LRP has a steep learning curve to obtain proficiency during which patient safety may be compromised. We present an adapted modular training system which purpose to optimize the learning curve and perform a safe surgery.
A retrospective analysis of the LRP safe learning protocol applied during a fellowship program over eight years (2008-2015). The surgery was divided in 12 steps and 5 levels of difficulty. A maximum time interval was stipulated in 240 minutes. After an adaptation, the fellows had 120 minutes to perform all the corresponding modules to its accumulated skill. The participants gradually and safely pass through the steps and difficulty levels. Surgeries performed by fellows were analyzed as a single group and compared to a prior series performed by tutor.
In eight years, 250 LRP were performed (25 per apprentice) during fellowship program and 150 procedures after completion. The baseline characteristics were comparable. Most cases operated were of intermediate risk. Mean operative time was longer in the fellow group when compared to the tutor (150 min). Mean estimated blood loss were similar among the groups. Functional and oncological outcomes were better in the Tutor´s group. No conversion to open surgery was performed.
The LRP safe learning protocol proved to be an effective method to optimize the learning curve and perform safe surgery. However, the tutor's functional and oncological results were better, showing that this is a procedure with a steep learning curve and proficiency demands more than 25 cases.
LRP 具有陡峭的学习曲线,在此期间可能会危及患者安全。我们提出了一种改良的模块化培训系统,旨在优化学习曲线并进行安全手术。
回顾性分析了在 8 年(2008-2015 年) fellowship 计划中应用的 LRP 安全学习方案。手术分为 12 个步骤和 5 个难度级别。规定了最大时间间隔为 240 分钟。经过适应,学员有 120 分钟的时间来完成所有与其累计技能相对应的模块。参与者逐渐安全地通过各个步骤和难度级别。将学员完成的手术作为一个单独的组进行分析,并与导师之前的系列手术进行比较。
在 8 年的时间里,在 fellowship 计划中进行了 250 例 LRP(每位学员 25 例),并在完成后进行了 150 例手术。基线特征具有可比性。大多数手术为中危手术。与导师相比,学员组的手术时间较长(150 分钟)。各组间估计失血量相似。导师组的功能和肿瘤学结果更好。未行中转开放手术。
LRP 安全学习方案被证明是优化学习曲线和进行安全手术的有效方法。然而,导师的功能和肿瘤学结果更好,表明这是一个学习曲线陡峭的手术,需要超过 25 例才能熟练掌握。
