Abstract

Medical simulation has proven to enhance surgeons' skills in a safe environment. 3D printing offers a low-cost alternative for technical learning. This study describes the creation of a biliary anastomosis simulator using additive manufacturing and its initial evaluation by surgeons at various training stages. A retrospective, descriptive, observational study with non-probabilistic sampling was conducted. The biliary anastomosis simulator was created using 3D printing and liquid silicone molding. It was evaluated through a Likert-type survey, measuring fidelity, functionality, and educational quality. The total cost of the device was calculated. Descriptive statistics were applied. Twelve participants evaluated the simulator: 3 HPB surgeons, 4 HPB residents, and 5 general surgery residents. The average age was 35.33 ± 11.02 years. Of the sample, 75% had experience with inorganic simulators, and 50% had experience in biliary anastomoses. The average surgical exposure was 9.75 ± 11,01 years. The weakest points were anatomical accuracy (2.58/5) and similarity to the bile duct (2.67/5). Functionality (3.83/5) and durability (4.83/5) were highly rated. Educational quality received a score of 4.67/5. Self-efficacy varied by experience: HPB surgeons (1.11/5), residents (3.42/5), and rotating residents (5/5). The overall evaluation was 4.5/5. Our study confirmed the feasibility of a 3D biliary anastomosis simulator using additive manufacturing and silicone molding. This accessible model facilitates the learning of biliary anastomoses among surgeons in training. Future research should demonstrate its educational efficacy and validity.
