Purpose <p>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.</p> Methods <p>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.</p> Results <p>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).</p> Conclusions <p>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.</p>
