Hernia is commonly known as small intestinal gas, the most common hernia is extra-abdominal hernia, 95% of which is inguinal hernia, which is a common and frequent disease. It is now believed that local inguinal tissue weakness is the root cause of hernia, and surgery is the only effective means of treatment, tension-free hernia repair is the most advanced treatment option. Deficiencies of traditional surgery The treatment of inguinal hernia has experienced a long evolution of more than 100 years, there is a common defect in the traditional surgery, that is, the tension of the repair site, in a normal position but not the same defective neighboring tissues and structures forcibly pulled together to close the suture, the tension is very large, destroying the original physiological and anatomical structure, which will lead to the patient’s local discomfort, but also cause the local ischemia, collagen decomposition increased. Tissue ischemia, collagen decomposition increases, leading to immediate or delayed tearing of the tendon ligament, resulting in a new defect, creating conditions for the recurrence of hernia, which is not in line with the principles of surgery. What is tension-free hernia repair Tension-free hernia repair is a new method of strengthening the posterior wall of the inguinal canal developed since the 1980s, i.e., to strengthen the posterior wall of the inguinal canal by transplanting biosynthetic materials. The procedure is scientifically designed to conform to the anatomy and physiology of the normal inguinal canal. Compared with traditional surgery, it not only broadens the range of surgical indications, but also has the advantages of less trauma, less postoperative pain, quicker recovery, fewer complications, and lower recurrence rate, which is well received by the majority of clinical surgeons and patients. The procedure has been described as an epoch-making surgery at the end of the 20th century, and has been described as a milestone in hernia repair. Advantages of Tension-Free Hernia Repair Some readers may ask, what are the specific advantages of this procedure? To answer this question one must start with the tension-free surgery itself. The surgery has the following characteristics: 1, the surgical design is scientific and reasonable, in line with the anatomy and physiology of the normal inguinal canal; 2, the surgery is less traumatic and less painful, and tension-free repair can be accomplished by making a 4-5 cm incision in the inguinal area; 3, it is highly safe. In addition, the surgery also has the following advantages: (1) early recovery of the patient’s autonomy: after the traditional repair surgery, the general use of the 3 × 3 principle, that is, 3 days of absolute bed rest, 3 weeks of light activities, 3-6 months after the resumption of light physical labor. After tension-free repair surgery, you can get out of bed after 3 hours, after 3 days you can carry out light activities, and after 3 weeks you can resume light physical labor and moderate aerobic exercise; (2) fewer complications: the local pain is slight, no need to stay in bed for a long period of time, and you can get out of the ground in 3 hours after the surgery, so the incidence of postoperative complications is significantly reduced; (3) low recurrence rate: the postoperative recurrence rate of the traditional surgical methods is 10%-15%, while the tension-free The recurrence rate after tension hernia repair is less than 1% in incipient hernia; (4) low infection rate; artificial composite material has good histocompatibility, no rejection reaction, and good anti-infection ability, which will not increase the infection rate of the incision; (5) the indications are relatively wider, applicable to: (1) all kinds of primary and recurrent inguinal hernia and femoral hernia. ② moderate increase in abdominal pressure and the posterior inguinal wall is more weak patients, such as chronic cough, prostate hypertrophy urinary difficulties, habitual constipation and elderly patients (over 80 years old). ③ Elderly patients with cardiovascular disease. ④ Patients with huge hernia ring, liver cirrhosis with mild ascites. Can hernia surgery be performed under local anesthesia Through long-term clinical accumulation, we now use local anesthesia for most inguinal hernia patients, which not only reduces part of the medical cost, but also increases the safety of the operation, and we have once performed this operation for 92-year-old hernia patients and achieved success. Except for multiple surgeries and excessive local scars, as long as the nerves around the incision can be blocked, satisfactory pain relief can be achieved. The rate of local anesthesia use in our hospital is among the leading rates in China when compared with the national and international literature. There are no drugs that can cure hernia without surgery Perhaps there are still readers who ask that they can often see individual newspaper advertisements claiming that a certain drug can cure hernia, thus eliminating the pain of surgery. In fact, the international academic community has long reached a consensus that adult hernia is impossible to self-healing, in other words, with the exception of some pediatric hernia, adult hernia must be cured through surgical means. No matter whether it is internal medicine or external medicine is impossible to cure hernia, but also some small medical institutions use local injection of sclerosing agent method of treatment, which not only can not cure the disease, but also can cause local adhesion, increase the difficulty of subsequent surgery, more not desirable.
