Development and Initial Assessment of a Novel and Customized Bile Duct Simulator for Handsewn Anastomosis Training

The Use of Silicone Simulators for Bile Duct Anastomosis Education in Medical Conferences for the Purpose of Improving the Canadian Medical Education Directives for Specialists (CanMEDS) Competencies

This technical report explores the potential of including silicone bile duct simulators for the purpose of completing a bile duct anastomosis (BDA) in medical conferences. The purpose is to target the need for exposure to more surgical skills and to contribute to the Canadian Medical Education Directives for Specialists (CanMEDS) requirements, as per the Royal College of Physicians and Surgeons of Canada.  Data collection was completed at the 2023 Canadian Conference for the Advancement of Surgical Education (C-CASE) in Montreal, Canada. For several years, the quality improvement feedback received at the end of these conferences suggested a few areas of improvement, one of which was related to the concept of return on investment (ROI). The participants spend a considerable amount of funds to travel to the conferences but feel that the only measurable gains are at a research capacity and thus only relate to two CanMEDS competencies. By leveraging C-CASE, the aim is to enhance students' educational experience during events they already intend to attend. Initially, students participated in a five-part simulation workshop and engaged in a think-aloud protocol (TAO). From there, nine participants were recruited for a focus group to further understand the perceived educational value and feedback on both the simulators and the conference structure.

The Iterative Design and Development of an Affordable Ultrasound Simulator

Simulation-based medical education (SBME) offers a secure and controlled environment for training in ultrasound-related clinical skills such as nerve blocking and intravenous cannulation. Sonographer training for point-of-care ultrasound often adopts the train-the-trainer (TTT) model, wherein a select group of sonographers receive on-site training to subsequently instruct others. This model traditionally relies on expensive commercial ultrasound simulators, which presents a barrier to the scale-up of the TTT model. This study aims to address the need for cost-effective ultrasound simulators suitable for both initial and cascaded TTT. The objective of this report is to present the design and development of an affordable ultrasound simulator, which mimics anatomical features under ultrasound. The simulator was created using additive manufacturing techniques, including 3D printing, ballistic gel, and silicone work. We report on three development-feedback iterations, with feedback provided by an experienced sonographer from FUJIFILM Sonosite Canada Inc. using the think-aloud approach. Overall the results indicate that de-gassed silicone may serve as a good medium; vessels are best produced as hollow canals within the de-gassed silicone; 3D-printed bones cast acoustic shadows, which are reduced by increasing rigidity of the structures, and 3D printing filament and silicone can be used for nerve bundles. Future developments will focus on achieving anatomical accuracy, exploring alternative materials and printing parameters for the bones, and analyzing embedded structures at varying depths within the silicone. The next steps involve integrating the simulator into ultrasound curricula for a formal assessment of its effectiveness as a training tool.
