Hernia is a common disease that is mainly referred to as inguinal hernia. It manifests as a mass protruding from the inguinal region, which is obvious when walking or coughing while standing, and can disappear when resting; most of the intestines protrude through the abdominal wall defect, and can also be incorporated into the abdominal cavity. In severe cases, intussusception can occur, and the mass cannot disappear after protruding, accompanied by pain and severe abdominal pain, nausea, vomiting, anal stoppage, defecation and other symptoms of intestinal obstruction, which is due to intestinal tube prolapse and cannot be retracted, and intestinal tube obstruction occurs. Surgery is the only effective way to treat hernia, and early surgery should be performed when hernia is found, instead of waiting for the occurrence of intussusception and forcing emergency surgery. At present, the traditional surgical method is used in Wuhan, which is an outdated surgical method with severe postoperative pain and recurrence rate of up to 20%, seriously affecting the quality of life of patients and making many patients afraid of surgical treatment. They have long been rejected and discarded, and the only formal treatment is surgery to repair the abdominal wall defect. Tension-free hernia mesh repair surgery, which has been carried out in North America, Western Europe and the United Kingdom since 1990, has become the unified formal surgical method. However, most hospitals in China still use the old surgical method, which has remained unchanged for decades. Since 1996, we have adopted this new surgical treatment method of tension-free mesh repair, which has greatly reduced postoperative pain and recurrence rate to <1%. The recurrence rate of mesh repair is less than 1%. The currently popular "plugging" procedure in China is only suitable for small hernias, but not for recurrent hernias or huge extra-abdominal hernias. Some hernia patients with coexisting diseases such as prostatic hyperplasia, cirrhosis of the liver, chronic bronchial disease and emphysema are traditionally considered as contraindications to hernia surgery because of the high recurrence rate after traditional surgery. Mesh repair breaks the traditional contraindication, mainly because of the very low recurrence rate.
