【 摘 要 】

PURPOSE: To describe a cadaver model and to compare different techniques to correct midline incisional hernia using the tension at the musculoaponeurotic layer as a parameter. METHODS: Twenty-four male cadavers were used to characterize the model. The tensile force applied to the anterior layers of the rectus abdominis muscle was measured after the linea alba was resected to create an abdominal wall defect. A dynamometer was used to measure the tensile force necessary to cause a 10-mm displacement of the tissues towards the midline. An index that allows comparison of tensile forces from different points was calculated by dividing the tensile force by the distance between the point of force application at the aponeurosis and the midline. RESULTS: Cadaver is a good model for the study of midline incisional hernia. CONCLUSION: Cadaver can be used effectively as a model to evaluate tension of the abdominal wall when tissue advancement and musculoaponeurotic flaps are performed in the repair of midline incisional hernia.
