Abstract: The choice of prosthetic materials for recurrent hernia repair directly impacts surgical outcomes and prognosis. For recurrent inguinal hernias, the original surgical approach should be avoided, with polypropylene mesh being the preferred choice, while biological mesh should only be considered cautiously in cases of potential infection; for recurrent incisional hernias, mechanical reinforcement is essential, and medium/heavyweight synthetic meshes are recommended, whereas biological meshes are not advised due to their high recurrence rate and complication risks; for recurrent parastomal hernias, the Sugarbaker technique combined with large-pore synthetic mesh (e.g., polypropylene) is suggested, as biological meshes demonstrate suboptimal efficacy; for recurrent hiatal hernias, mesh reinforcement is required, with synthetic meshes preferred for larger defects. The selection of patch materials should be individualized in combination with the type of hernia, the characteristics of the defect and the patient's condition. Moreover, the current clinical evidence related to patch selection is insufficient and the sample size is limited.Future directions focus on the development of smart meshes, leveraging bionic design, dynamic mechanical responsiveness, and real-time monitoring technologies to advance hernia repair toward precision and functional optimization.
