Hernias are commonly referred to as inguinal hernias, which are a common disease. It manifests as a mass protruding from the inguinal region, which is obvious when standing and walking or coughing, 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 are due to intestinal tube prolapse and cannot be retracted, and intestinal tube obstruction occurs. Surgery is the only effective way to treat hernia, and hernia should be operated early instead of waiting for the occurrence of intussusception and forcing emergency surgery. Traditional surgical methods have severe postoperative pain and a recurrence rate of up to 20%, which seriously affect the quality of life of patients and make many patients afraid of surgical treatment. The only formal treatment is surgical repair of the abdominal wall defect. Since 1990, the tension-free hernia mesh repair surgery, which has long been carried out in North America, Western Europe and the United Kingdom, has become the unified formal surgical method. Since 1996, we have adopted this tension-free mesh repair surgical treatment method. The recurrence rate of mesh repair is less than 1%, and the currently popular “mesh plugging” surgery is only suitable for small hernias (internal hernia ≤ 4 cm), and is not suitable for recurrent hernias and large extra-abdominal hernias. The cost of laparoscopic hernia repair and mesh plug repair is high, with the cost of materials alone reaching several thousand dollars and the entire operation costing nearly ten thousand dollars. Some hernia patients with coexisting diseases such as prostatic hyperplasia, cirrhosis, chronic old age and emphysema are traditionally considered as contraindications to hernia surgery because of the high recurrence rate after traditional surgery. The main reason for mesh repair to break the traditional contraindication is the extremely low recurrence rate. Our general surgery department started this operation in 1996 (the earliest in China) and has completed more than 2000 cases, including more than 80 cases of various refractory hernias, such as recurrent hernia and giant hernia, with a recurrence rate of less than 0.2%. Postoperative local pain is mild, no painkillers are needed, and you can get out of bed and walk upright on the same day after surgery. There is no need to worry about the mesh being a foreign body, and no rejection reaction was found in the last 30 years of clinical use in the United States.
