Abstract

OBJECTIVE

The authors evaluated the accuracies and ease of use of several commonly used microanastomosis training models (synthetic tube, chicken wing, and living rat model).

METHODS

A survey was conducted among neurosurgeons and neurosurgery residents at a workshop held in 2009 at the authors' institute. Questions addressed model accuracy (similarity to real vessels and actual procedures) and practicality (availability of materials and ease of application in daily practice). Answers to each question were rated using a 5-point scale. Participants were also asked what types of training methods they would chose to improve their skills and to introduce the topic to other neurosurgeons or neurosurgery residents.

RESULTS

Of the 24 participants, 20 (83.3%) responded to the survey. The living rat model was favored for model accuracy (p < 0.001; synthetic tube -0.95 +/- 0.686, chicken wing, 0.15 +/- 0.587, and rat, 1.75 +/- 0.444) and the chicken wing model for practicality (p < 0.001; synthetic tube -1.55 +/- 0.605, chicken wing, 1.80 +/- 0.523, and rat, 1.30 +/- 0.923). All (100%) chose the living rat model for improving their skills, and for introducing the subject to other neurosurgeons or neurosurgery residents, the chicken wing and living rat models were selected by 18 (90%) and 20 (100%), respectively.

CONCLUSION

Of 3 methods examined, the chicken wing model was found to be the most practical, but the living rat model was found to represent reality the best. We recommend the chicken wing model to train surgeons who have mastered basic techniques, and the living rat model for experienced surgeons to maintain skill levels.

摘要

目的

作者评估了几种常用的显微吻合训练模型(合成管、鸡翅和活体大鼠模型)的准确性和易用性。

方法

2009年在作者所在机构举办的一次研讨会上,对神经外科医生和神经外科住院医师进行了一项调查。问题涉及模型准确性(与真实血管和实际操作的相似性)和实用性(材料可用性及在日常实践中的易用性)。每个问题的答案采用5分制评分。参与者还被问及他们会选择何种训练方法来提高技能,以及将该主题介绍给其他神经外科医生或神经外科住院医师。

结果

24名参与者中有20名(83.3%)回复了调查。活体大鼠模型在模型准确性方面更受青睐(p<0.001;合成管为-0.95±0.686,鸡翅为0.15±0.587,大鼠为1.75±0.444),而鸡翅模型在实用性方面更具优势(p<0.001;合成管为-1.55±0.605,鸡翅为1.80±0.523,大鼠为1.30±0.923)。所有参与者(100%)都选择活体大鼠模型来提高技能,在将该主题介绍给其他神经外科医生或神经外科住院医师方面,分别有18名(90%)和20名(100%)选择了鸡翅模型和活体大鼠模型。

结论

在所研究的3种方法中,鸡翅模型被发现是最实用的,但活体大鼠模型被认为最能代表实际情况。我们建议用鸡翅模型训练已掌握基本技术的外科医生,用活体大鼠模型供经验丰富的外科医生维持技能水平。
