Incisional hernia is an iatrogenic condition characterized by diverse forms, significant variability, and complex classification. It presents challenges and uncertainties in clinical treatment. Significant progress has been made in the diagnosis of incisional hernias, surgical techniques, and the development of prosthetic materials. Building upon the "Guidelines for the Diagnosis and Treatment of Abdominal Wall Incisional Hernia (2018 Edition)," domestic experts in hernia and abdominal wall surgery have conducted discussions and revisions. These updates, guided by evidence-based medical evaluation standards, address issues such as complex abdominal wall conditions, abdominal wall dysfunction, principles of hernia treatment, methods for defect closure, perioperative management, and follow-up and patient education. The aim is to further enhance the diagnostic and treatment standards for abdominal wall incisional hernias in China.
