Abstract
PURPOSE
We developed a 3D-printed phantom model for ultrasound-guided caudal block for educational or training purposes because there have been no reports of the 3D-printed phantom model for ultrasound-guided caudal block. This study aimed to identify the needs for the phantom model in a lecture and demonstration at hands-on training (HoT) to promote the use of caudal block for sufficient pain control during high-dose-rate intracavitary/interstitial brachytherapy for gynecological cancers.
MATERIALS AND METHODS
The sacrum and formwork were designed by computed tomography imaging. A 3D-modeling software program was used to create the sacrum and formwork. The phantom was solidified by injecting a gelatin-based gel. Ultrasonography was performed to visualize the sacral hiatus and puncture needle in the phantom. In October 2023, 10 radiation oncologists who did not perform caudal block in daily clinical practice from ten Japanese facilities participated in HoT on ultrasound-guided caudal block. After the HoT, questionnaires were distributed to each participant, and feedback was obtained through online channels.
RESULTS
After receiving a lecture and demonstration on ultrasound-guided caudal block, 90% of the respondents would like to practice the procedure in their daily clinical practice. Moreover, 100% of the respondents would like to use the 3D-printed phantom model for ultrasound-guided caudal block for educational or training purposes.
CONCLUSION
The 3D-printed phantom model for ultrasound-guided caudal block can be used in training and is in demand for facilities introducing caudal block.
期刊介绍：
Brachytherapy is an international and multidisciplinary journal that publishes original peer-reviewed articles and selected reviews on the techniques and clinical applications of interstitial and intracavitary radiation in the management of cancers. Laboratory and experimental research relevant to clinical practice is also included. Related disciplines include medical physics, medical oncology, and radiation oncology and radiology. Brachytherapy publishes technical advances, original articles, reviews, and point/counterpoint on controversial issues. Original articles that address any aspect of brachytherapy are invited. Letters to the Editor-in-Chief are encouraged.
