Abstract

The component separation CS is a core approach for repairing large and complex abdominal wall defects. Its surgical manipulation inevitably involves interference with key anatomical structures of the abdominal wall, and effective protection of these structures directly impacts postoperative complications and long-term functional recovery. A thorough understanding and mastery of the critical anatomical layers, as well as the course and distribution of blood vessels and nerves in the abdominal wall, are prerequisites for the safe implementation of CS. Protecting the abdominal wall vascular system, neural innervation, and the integrity of the myofascial structures is essential to avoiding the anatomical risks associated with CS. The anterior approach CS that preserves perforating vessels, the posterior approach CS that retains intact neurovascular bundles, and endoscopic or robot-assisted minimally invasive techniques all provide significant support for implementing individualized CS that balances efficacy and safety, while also enhancing the safety and long-term outcomes of abdominal wall reconstruction. Greater refinement, minimally invasive application, intelligence, and functional restoration represent the future direction of CS.
