Abdominal hernia surgery has evolved beyond simple defect closure into a discipline focused on restoring abdominal wall function, reducing wound morbidity, and improving long-term, patient-centred outcomes. Abdominal Hernia Surgery - Principles, Techniques, and Innovations in Open and Minimally Invasive Repair provides a practical, evidence-informed overview for surgeons and trainees navigating a broad range of operative options. The book integrates core abdominal wall anatomy, contemporary open and minimally invasive strategies, and clinical reasoning required to align technique with patient factors, defect characteristics, and resource settings. It presents current concepts in mesh reinforcement, plane selection, and operative planning, and strategies to minimise recurrence and chronic pain, while emphasising safety, reproducibility, and tailored decision-making. By focusing on the application of principles in clinical practice, this volume supports perioperative counselling, technical development, and structured surgical judgement. It also links established standards with evolving approaches in abdominal wall reconstruction and hernia care.
