背景前哨淋巴结活检正成为早期乳腺癌分期研究的首选。前哨淋巴结的最佳识别需要利用放射性核素结合蓝色染料。伽马探针引导手术是目前许多外科医生不熟悉的技能。在外科技能实验室内进行适当的培训可以在广泛实施这项技术中发挥重要作用，但目前还没有合适的模型用于此目的。为了开发一种逼真的体模，用于教授和实践外科医生在乳腺癌中进行伽玛探头引导前哨淋巴结活检所需的核心新技能。我们描述了我们的前哨，淋巴结活检模拟器，其中包括一个躯干与其手臂延伸在一个操作位置的发展。可更换的乳房和腋窝由热塑性弹性体制成，具有类似的物理特性。和辐射衰减特性。放射性核素注入部位和放射性前哨淋巴结由填充有锝-99m的中空蓝色彩色PVC珠模拟。该模型允许演示和实践的注射技术，成像技术和伽玛探头引导下前哨淋巴结切除。我们认为前哨淋巴结活检的培训应该开始在外科技能实验室。我们已经开发的模型是能够提供一个准确的模拟所需的所有新的实用技能，准确的前哨淋巴结识别。这是一个重要的援助，培训在前哨淋巴结活检程序的乳腺癌。(C)2004 Etsevier Ltd.保留所有权利。
Background. Sentinel, node biopsy is becoming the staging investigation of choice for early breast cancer. Optimal identification of the sentinel node requires the utilization of a radionuclide in combination with blue dye. Gamma probe guided surgery is a skill that is currently unfamiliar to many surgeons. Appropriate training within the surgical skills laboratory could play a major role in the widespread implementation of this technique, but no suitable model currently exists for this purpose.Aim. To develop a realistic phantom for the teaching and practice of the core new skills required of a surgeon to perform gamma probe guided sentinel node biopsy in breast cancer.Methods. We describe the development of our sentinel, node biopsy simulator which consists of a torso with its arm extended in an operating position. The replaceable breast and axilla are constructed from a thermoplastic elastomer get, which has similar physical. and radiation attenuation properties to that of human tissue. Radionuclide injection sites and radioactive sentinel nodes are simulated by hollow blue Coloured PVC beads filled with Technetium-99m. The model allows demonstration and practice of injection techniques, imaging techniques and gamma probe guided removal of sentinel nodes.Conclusion. We believe that training for sentinel node biopsy should begin in the surgical skills laboratory. The model we have developed is able to provide an accurate simulation of all new practical skills required for accurate sentinel node identification. It is an important aid to training in the sentinel lymph node biopsy procedure for breast carcinoma. (C) 2004 Etsevier Ltd. All rights reserved.
