Despite being linked to improving patient outcomes and limiting costs, the use of vaginal hysterectomy is on the wane. Although a combination of reasons might explain this trend, one cause is a lack of practical training. An appropriate teaching model must therefore be devised. Currently, only low-fidelity simulators exist. Ewes provide an appropriate model for pelvic anatomy and are well-suited for testing vaginal mesh properties. This article sets out a vaginal hysterectomy procedure for use as an education and training model.
A multiparous ewe was the model. Surgery was performed under general anesthesia. The ewe was in a lithotomy position resembling that assumed by women on the operating table.
Two vaginal hysterectomies were performed on two ewes, following every step precisely as if the model were human. Each surgical step of vaginal hysterectomy performed on the ewe and on a woman were compared side by side. We identified that all surgical steps were particularly similar. The main limitations of this model are costs ($500/procedure), logistic problems (housing large animals), and public opposition to animal training models.
The ewe appears to be an appropriate model for teaching and training of vaginal hysterectomy.
尽管阴道子宫切除术与改善患者预后和控制成本有关，但它的应用正在减少。尽管有多种原因可以解释这种趋势，但其中一个原因是缺乏实践培训。因此，必须设计出一种合适的教学模式。目前，仅存在低保真度模拟器。母羊为骨盆解剖结构提供了合适的模型，非常适合测试阴道网片的性能。本文提出了一种阴道子宫切除术，可作为一种教育和培训模型。
多胎母羊为模型。手术在全身麻醉下进行。母羊呈截石位，类似于手术台上的女性。
对两只母羊进行了两次阴道子宫切除术，每一步都严格按照如果模型是人类的情况进行操作。将在母羊和妇女身上进行的每一个阴道子宫切除术的手术步骤并排进行比较。我们发现所有的手术步骤都非常相似。这种模型的主要局限性是成本（每次手术 500 美元）、物流问题（饲养大型动物）和公众反对动物培训模型。
母羊似乎是阴道子宫切除术教学和培训的合适模型。
