I have suffered from hernia for more than 20 years, and I had an operation 10 years ago. The hernia operation failed because of carelessness. Last week, I did it again.

What is a hernia? Hernia is mostly caused by coughing, sneezing, overexertion, abdominal obesity, forced defecation, pregnancy of women, excessive crying of children, and degenerative changes in abdominal wall strength of the elderly. Negative pressure is generated in abdominal cavity, which causes the pressure in abdominal cavity to rise, forcing the organs in abdominal cavity to be free, such as small intestine, cecum, omentum, bladder, ovary and fallopian tube. Drill as soon as you see the hole, and the original part passes through the normal or abnormal weak point of the human body.

Tension-free hernia repair was proposed by Lichtenstein in 1989, but it has been used in clinic for many years. This new concept is a supplement and improvement to the traditional hernia repair. An important cause of hernia is the defect left on peritoneum and transverse fascia of abdomen when testis descends. The incompletely closed peritoneum forms a sheath-like process from which the contents of the abdominal cavity protrude outward.

Compared with the traditional hernia repair, it is necessary to stay in bed for 3 days absolutely, and only after 3 weeks can light activities be carried out, and often the lower limbs can not be completely straightened and bent when walking, otherwise the incision pain will be unbearable. Tension-free inguinal hernia can get out of bed on the first day after patch repair, and the activities of lower limbs and waist will not be affected by tension. Because it has no tension, the postoperative recurrence rate is even lower than 1%. There was no recurrence in this group, but the postoperative recurrence rate of traditional surgical methods was 10% ~ 15%.
