Mesh Weight of 45–60 g/m² Minimises Reoperation Risk in Laparoscopic Inguinal Hernia Repair: JAMA
A nationwide cohort study has found that using mesh weighing 45–60 g/m² in laparoscopic inguinal hernia repair minimized the risk of reoperation for recurrence, suggesting this range offers optimal surgical outcomes. The study, published in JAMA Surgery, analyzed long-term outcomes from a large patient population undergoing minimally invasive hernia repair. By comparing different mesh weights, the researchers identified a specific range that balances durability and tissue integration, reducing the likelihood of recurrence without increasing complications such as chronic pain or infection.
The authors noted that lighter meshes (<45 g/m²) were associated with higher recurrence rates, likely due to insufficient mechanical support, whereas heavier meshes (>60 g/m²) increased the risk of tissue reaction and discomfort. Patients receiving mesh in the 45–60 g/m² range experienced lower rates of reoperation, suggesting that this weight provides adequate strength while maintaining flexibility and biocompatibility. The study emphasizes that careful selection of mesh type and weight is critical to optimize long-term outcomes in laparoscopic inguinal hernia repair, a procedure widely performed worldwide.
In conclusion, this research highlights the importance of individualized surgical planning and evidence-based mesh selection. Surgeons are encouraged to consider mesh weight within the 45–60 g/m² range to reduce reoperation risk and enhance patient satisfaction. By identifying the optimal balance between mesh durability and tissue tolerance, this study offers practical guidance for improving laparoscopic hernia repair outcomes and minimizing postoperative complications. Future research may focus on patient-specific factors, such as age, comorbidities, and hernia characteristics, to further refine mesh selection and optimize surgical success.
