Abstract：
UNASSIGNED: Microanastomosis is a challenging technique requiring continuous training to be mastered. Several models have been proposed, but few effectively reflect a real bypass surgery; even fewer are reusable, most are not easily accessible, and the setting is often quite long. We aim to validate a simplified, ready-to-use, reusable, ergonomic bypass simulator.
UNASSIGNED: Twelve novice and two expert neurosurgeons completed eight End-to-End (EE), eight End-to-Side (ES), and eight Side-to-Side (SS) microanastomoses using 2-mm synthetic vessels. Data on time to perform bypass (TPB), number of sutures and time required to stop potential leaks were collected. After the last training, participants completed a Likert Like Survey for bypass simulator evaluation. Each participant was assessed using the Northwestern Objective Microanastomosis Assessment Tool (NOMAT).
UNASSIGNED: When comparing the first and last attempts, an improvement of the mean TPB was registered in both groups for the three types of microanastomosis. The improvement was always statistically significant in the novice group, while in the expert group, it was only significant for ES bypass. The NOMAT score improved in both groups, displaying statistical significance in the novices for EE bypass. The mean number of leakages, and the relative time for their resolution, also tended to progressively reduce in both groups by increasing the attempts. The Likert score expressed by the experts was slightly higher (25 vs. 24.58 by the novices).
UNASSIGNED: Our proposed bypass training model may represent a simplified, ready-to-use, reusable, ergonomic, and efficient system to improve eye-hand coordination and dexterity in performing microanastomoses.

摘要：
UNASSIGNED：微吻合是一项具有挑战性的技术，需要不断的训练才能掌握。已经提出了几种模型，但很少能有效反映真正的搭桥手术；可重复使用的更少，大多数都不容易接近，设置通常很长。我们的目标是验证一个简化的，随时可用，可重复使用，符合人体工程学的旁路模拟器。
未经评估：12名新手和2名神经外科专家完成了8个“端到端”（EE），八个端到端(ES)，和8个使用2毫米合成血管的侧对侧（SS）微吻合。执行旁路的时间数据（TPB），收集缝线的数量和阻止潜在泄漏所需的时间。在最后一次训练之后,参与者完成了LikertLike调查，以评估旁路模拟器。使用西北客观微吻合评估工具（NOMAT）评估每位参与者。
UNASSIGNED：比较第一次和最后一次尝试时，3种微吻合术组的平均TPB均有改善.新手组的改善始终具有统计学意义，在专家组中，这仅对ES旁路有意义。两组的NOMAT评分均有改善，显示EE旁路新手的统计意义。平均泄漏次数,以及它们解决的相对时间，通过增加尝试，两组也趋于逐渐减少。专家表达的李克特得分略高（25对新手24.58）。
