”Hernia is a common and frequent disease. The medical term “hernia” includes inguinal hernia (commonly known as small bowel gas), femoral hernia, incisional hernia, para-stoma hernia, umbilical hernia, white line hernia, semilunar hernia, lumbar hernia, etc., which are collectively called abdominal wall hernia. Although it is called “hernia”, the occurrence of this disease is not related to “gas”. The root cause is the weakness of different parts of the abdominal wall caused by various reasons, resulting in the protrusion of abdominal contents (mostly intestinal tubes) from the weakness to form a visible abdominal wall mass, which can become smaller or disappear with the change of body position. Therefore, repairing the weak abdominal wall will cure the abdominal wall hernia. In the case of inguinal hernia, many patients who were treated surgically in the early years must still have the impression that the surgical incision was not short, the postoperative pain and discomfort was obvious, it took a week or more to be discharged, and there were many recurrences. Nowadays, it is completely different. The use of minimally invasive techniques and patch repair of inguinal hernia (TEP/TAPP) and the improved open preperitoneal repair procedure allow patients to be discharged home on the first day after surgery and to take care of themselves in their daily life. The most satisfying aspect is that the recurrence rate is significantly reduced and the patient bears less risk. Similarly, in other abdominal wall hernias such as incisional hernia and parastomal hernia, the advantages of minimally invasive techniques and the use of patches are even more obvious, as large incisional hernia and parastomal hernia can often be satisfactorily repaired with only three incisions of less than 1 cm on the abdominal wall, and the patient recovers very quickly after surgery, avoiding the problems of large incisions, trauma, recurrence and slow recovery caused by traditional surgery. To be clear, so far, there is no second more effective treatment for hernia except surgical repair of the weak zone of the abdominal wall, which has been clinically proven to be clearly effective in a large number of cases. Secondly, once a hernia appears, the earlier it is treated, the better the results and the fewer the complications.
