Abstract:
Objective:To describe a low-cost, reproducible phantom model for training medical practitioners in ultrasound-guided ethanol ablation (EA) of a cystic thyroid nodule.
Methods:The model of cyst contents was created using a mixture of coffee powder, cornstarch and water to mimic colloidal contents. This was injected into the finger of a cut surgical glove secured with transparent tape to serve as an inflatable capsule and placed inside a chicken breast. This setup allows practitioners to perform key ultrasound-guided ethanol ablation techniques including spinal needle insertion, cyst aspiration, saline flushing, re-aspiration and ethanol injection.
Results:The phantom model was assembled for PhP 150.30 per unit and took approximately 5 minutes to construct. This model was demonstrated to be a cost-effective and simple method for enabling specialists to practice and enhance their skills in ultrasound-guided ethanol ablation of a cystic thyroid nodule.
Conclusion:The described phantom model provides an accessible and practical training tool for healthcare providers to gain proficiency in ultrasound-guided ethanol ablation of a cystic thyroid nodule in a safe and controlled setting prior to actual patient handling.
