Abstract: Abdominal incisional hernia is caused by poor healing of myofascial layer of abdominal wall and abdominal visceral organs protruding through the defect after abdominal surgery. The incidence of abdominal incisional hernia is 5.0%‒20.0%, even higher after hepato-biliary and pancreatic surgery. Although great progress has been made in the methods of abdominal incision closure, hernia repair technology and materials, the overall incidence, repair effect and prognosis of abdominal incisional hernia are still not significantly improved. The incisional hernias after hepatobiliary and pancreatic surgery are relatively more complex, and the difficult problems of surgical repair are more prominent, including effectively controlling basic diseases, choosing a better surgical method, reasonably using a variety of abdominal wall defect closure and reconstruction techniques, and reducing the risk of postoperative complications. Relevant guidelines for abdominal incisional hernia repair and abdominal closure have been issued and updated all over the world. In order to improve the treatment of incisional hernia after hepatobiliary and pancreatic surgery and improve the prognosis of patients, the authors summarize the difficulties and new progress in the repair of incisional hernia after hepatobiliary and pancreatic surgery.
