“…Colpan et al 20 developed a realistic model for practicing vascular anastomoses using carotids from turkey necks, which were perfused during the procedure. Maluf et al 5 used the vascular pedicle of spleens from post morten pigs that had undergone splenectomy as an alternative model for training vascular anastomosis with mononylon suture.…”

“…There are descriptions in the literature of using synthetic materials, such as silicone and rubber gloves, animal tissues, and vegetable tissues, and of gaining practical experience using small animals (pigs, rats, and rabbits), as part of teaching of vascular anastomosis and development of the skills needed. [1][2][3][4][5] However, use of animal models is the most common objection raised by the public and by the students themselves, who question the practice of sacrificing animals for educational purposes. 6 The strict rules mandated by the Institutional Committees on Care and Utilization of Animals also make using such animal models in medical training difficult, contributing to the need to develop alternatives.…”

Balões de látex: um modelo alternativo e de baixo custo para treinamento de anastomoses vasculares no ensino médico

et al. 2018

Resumo O uso de simuladores na educação médica tem sido cada vez mais frequente, porém pouco acessíveis devido ao custo elevado. Foi desenvolvido para tal um modelo acessível e de baixo custo para o aprendizado e o treinamento de suturas e anastomoses vasculares em Laboratório de Bases das Técnicas Cirúrgicas. Foram utilizados balões de látex de cores variadas, fio de polipropileno 6.0 e outros materiais específicos para sutura vascular (porta-agulhas e pinças). Para facilitar o reparo dos balões, eles foram fixados em parafusos sobre placas de madeira. Foram feitas anastomoses terminoterminal, terminolateral e laterolateral e construção de patch. A perviedade da anastomose foi testada a partir da injeção de água em uma extremidade do balão e a observação da saída do conteúdo líquido na extremidade oposta. As vantagens observadas nesse modelo de treinamento para anastomoses foram a maleabilidade, a resistência à passagem do fio e o fato de ser inorgânico. Os balões de látex são uma alternativa barata, viável, não perecível e de uso prolongado no ensino e treinamento das suturas e anastomoses arteriais.

“…Porcine thigh models are useful in the microsurgery training of novice microsurgeons as they offer vessels of larger diameters (upto 6 mm) and are longer, therefore allowing for multiple anastomosis attempts (Steffens et al, ; Hong et al, ; Nam et al, ). Porcine spleen (Maluf Junior et al, ) and coronary vessels (Schoffl et al, ) have a diameter ranging from 0.5 to 2.5 mm, which means they can be used for mastering anastomosis techniques of smaller diameter vessels. All these cadaveric porcine models were descriptive research studies and none of them have yet been validated using randomized controlled trials.…”

Current status of simulation and training models in microsurgery: A systematic review

et al. 2019

With the prolific uptake of simulation-based training courses, this systematic review aims to identify the available microsurgical simulation and training models, their status of validation, associated studies, and levels of evidence (LoE) for each training model, thereby establishing a level of recommendation (LoR). MEDLINE, Embase, and the Cochrane Library databases were searched for English language articles, describing microsurgery simulators and/or validation studies. All studies were assessed for LoE, and each model was subsequently awarded a LoR using a modified Oxford Centre for Evidence-Based Medicine classification, adapted for education, with 1 being the highest and 4 the lowest score. A total of 86 studies were identified describing 64 models and simulators ranging from bench models, cadaveric animal tissue, cadaveric human tissue, live animal models, virtual reality simulators, and training curricula. Of these, 49 simulators had at least one validation study. Models were assessed for face (n = 42), content (n = 31), construct (n = 25), transfer (n = 10), and concurrent validity (n = 1) by these studies. The most commonly identified modality was bench models (n = 28) followed by cadaveric animal tissue (n = 24). The cryopreserved rat aorta model received the highest LoR followed by chicken wing, chicken thigh and practice cardboard models. Microsurgery simulation is a growing field and increasing numbers of models are being produced. However, there are still only a few validation studies with a high LoE. It is therefore imperative that training models and/or programs are evaluated for validity and efficacy in order to allow utilization in microsurgical skills acquisition.

“…3 This deficiency is caused by the high cost of equipment necessary for microsurgical practices. 3-5 Several alternatives are currently under development to avoid this situation and are showing promising results, such as endoscopes 6,7 and laparoscopes. 8,9 These devices have started a new era of video microsurgery; however, despite the high quality of their images, these devices have major limitations related to their short focal distance and high cost.…”

An alternative experimental model for training in microsurgery

Abstract: the use of pig spleen, which would be discarded after splenectomy, is an excellent model for microsurgical training, since besides having the consistency and sensitivity of a real model, it saves the sacrifice of a new animal model in the initial learning phase of this technique.
