Phantom and simulation models are valuable training tools for teaching and skill enhancement, yet high costs and limitations of commercial options drive the search for alternatives. This study evaluated the locally sourced phantom models developed for transvaginal and transabdominal gynecologic interventional ultrasound procedures, aiming to cater to the educational needs of OB-GYN ultrasound subspecialists.
Four phantom models simulating biopsy and cyst aspiration/paracentesis through transvaginal and transabdominal approaches, were developed, and assessed by 37 ultrasound subspecialists in obstetrics and gynecology. The respondents, comprising 19 experienced and 18 with limited exposure to guided procedures, utilized an 11-item Likert-scored questionnaire to evaluate the models' acceptability and suitability for training. Responses were analyzed using descriptive statistics.
Both experienced and less-experienced groups consistently assigned high scores, particularly highlighting the realistic ultrasound image and positioning of structures. The models proved effective in enhancing confidence and proficiency during simulation-based training for probe manipulation, aspiration, and biopsy procedures. While respondents identified concerns like durability and needle track marks, no significant differences emerged between the two groups in evaluating the model.
The overall evaluation of the developed phantom model was positive, showcasing its acceptability among end-users and suitability for training ultrasound-guided procedures in obstetrics and gynecology. The identified issues provide valuable insights for potential improvements in future iterations of the model.
体模和模拟模型是用于教学和技能提升的宝贵训练工具，但商业产品的高成本和局限性促使人们寻找替代方案。本研究评估了为经阴道和经腹妇科介入超声检查程序开发的本地采购体模模型，旨在满足妇产科超声亚专科医生的教育需求。
开发了四种模拟经阴道和经腹途径进行活检及囊肿抽吸/穿刺术的体模模型，并由37名妇产科超声亚专科医生进行评估。受访者包括19名经验丰富者和18名对引导程序接触有限者，他们使用一份11项李克特量表问卷来评估模型对训练的可接受性和适用性。使用描述性统计分析回答结果。
经验丰富组和经验不足组均一致给予高分，尤其强调了逼真的超声图像和结构定位。这些模型在基于模拟的探头操作、抽吸和活检程序训练中被证明能有效增强信心和提高熟练程度。虽然受访者指出了诸如耐用性和针道痕迹等问题，但两组在评估模型时未出现显著差异。
对所开发体模模型的总体评价是积极的，表明其在最终用户中具有可接受性，且适用于妇产科超声引导程序的训练。所发现的问题为该模型未来版本的潜在改进提供了有价值的见解。
