ALT The surgical human resource is a limiting factor in meeting the demands for surgical services in low-income settings. Groin hernia represents a common surgical condition and its repair is among the most commonly performed surgical procedures worldwide. Still, the number of procedures performed needs to increase drastically in order to meet the need for this procedure. In this study, trainees enrolled in the CapaCare surgical training program in Sierra Leone will participate in a simulation-based course in inguinal hernia repair. The aim of the study is to investigate if the learning curve to learn how to perform inguinal hernia repair on patients is affected as a result of first learning how to perform this procedure on 3D models.
