Development of an affordable fascia closure model to train surgical residents

The primary goal of this study was to evaluate the effectiveness of a novel, low-cost simulation model for training surgical residents in midline laparotomy closure, a critical skill that is challenging to master and often insufficiently emphasized in surgical education. The research aimed to determine whether this simulation model can provide a realistic, cost-effective alternative to traditional training methods. A multi-layered abdominal wall closure simulation model was developed using commercially available materials totaling 54 (US $). This model included artificial layers representing skin, subcutaneous fat, and fascia. A survey using a 5-point Likert scale was conducted among surgical faculty and senior residents to assess the model's realism and utility in training scenarios. Fourteen attending surgeons and four residents participated in the evaluation. The model received high marks for its realistic representation of a midline laparotomy, with scores ranging from 3 to 5 and a mean of 4.28 (± 0.57). The texture of the fascia during needle insertion was rated between 2 and 5, averaging 4.17 (± 0.79). Overall, the participants rated the model's effectiveness in training for midline laparotomy closure between 3 and 5, with a mean score of 4.44 (± 0.62). Our study supports the potential of simulation-based training models in surgical education, particularly for complex procedural skills like midline laparotomy closure. The abdominal wall simulation model, with its realistic features and cost-effectiveness, offers a practical and scalable training tool. Endorsed by both faculty and residents, it demonstrates a significant advancement in providing accessible, risk-free surgical training that can be crucial for enhancing the competency of surgical trainees.
