Exploring Variable Approaches in Complex Hernia Repair: A Comprehensive Literature Review

Surgeons have long grappled with categorizing complex hernias, leading to varied interpretations and fluctuating incidence rates. Complex Abdominal Wall Reconstruction (CAWR) addresses repairs for large hernias, with defined factors including size, previous repairs, mesh placement, infections, and comorbidities. This review explores pivotal surgical techniques for complex hernia repair, starting with Preoperative Progressive Pneumoperitoneum (PPP) and progressing to innovative methods like Botulinum Toxin Type A. Mesh fixation, both open and laparoscopic, plays a crucial role, with synthetic and biological mesh options discussed. Hybrid techniques and the "sandwich" approach are proposed for intricate cases. Each technique presents advantages and limitations, emphasizing the ongoing quest for optimal outcomes.
