Surgical Approaches to Complex Hernia Repair: A Meta-Analysis

Complex hernias, including recurrent, large, and those involving multiple abdominal wall layers, pose significant challenges for surgical repair. The decision-making process for the appropriate surgical approach is crucial to optimize outcomes and minimize the risk of recurrence. This meta-analysis aims to compare the effectiveness and safety of various surgical approaches for complex hernia repair, including open, laparoscopic, and robotic-assisted techniques. We systematically reviewed and synthesized data from multiple randomized controlled trials, cohort studies, and case series to evaluate key outcomes, such as complication rates, recurrence rates, operative time, hospital stay, and long-term quality of life. The analysis also considers the impact of different mesh types, such as synthetic versus biologic mesh, and the role of abdominal wall reconstruction techniques, such as component separation or the use of laparoscopic assistance, in improving repair outcomes. Our results show that laparoscopic and robotic-assisted hernia repairs are associated with reduced hospital stays and faster recovery times compared to open surgery, although the operative time may be longer. Mesh-related complications, such as infection or seroma formation, remain a concern across all approaches, but robotic-assisted surgery appears to offer advantages in terms of reduced recurrence rates and better cosmetic outcomes. We also explore the role of patient-related factors, such as obesity, comorbidities, and the presence of prior abdominal surgery, in determining the optimal surgical approach. In conclusion, laparoscopic and robotic-assisted approaches offer significant advantages for complex hernia repair in terms of recovery and complication management, though open surgery remains a valuable option in certain clinical scenarios. The choice of approach should be individualized, taking into account patient-specific factors, surgeon experience, and the complexity of the hernia. This meta-analysis underscores the importance of a tailored surgical approach to complex hernia repair for achieving the best possible long-term outcomes.
