A variety of diaphragmatic and non-diaphragmatic pathologies may require resection, reconstruction, or repair of the diaphragm. Adequate reconstruction is crucial in cases of diaphragmatic resection to prevent the herniation of abdominal organs into the chest and to maintain optimal respiratory function. This article aims to provide a detailed overview of the techniques used for surgical diaphragm reconstruction, taking into account factors such as the size and location of the defect, available options for reconstructive materials, potential challenges and pitfalls, and considerations related to the recurrence or failure of the repair.
