Modern surgical anatomy has confirmed that the breakage or loosening of the transversal abdominal fascia is the most fundamental cause of inguinal hernia (hernia or small bowel gas), and restoration of the anatomical integrity of the transversal abdominal fascia is the basic principle that should be followed in any kind of hernia repair. Operations that violate this principle are an important factor in hernia recurrence after inguinal hernia repair. Laparoscopic hernia repair is designed to follow this principle, using a large patch to cover the entire abdominal wall defect area, including hiatal hernia, rectal hernia, femoral hernia, etc., effectively restoring the integrity of the transversal abdominal fascia, more thorough repair, lower recurrence rate. Open tension-free hernia repair has been developed for more than 20 years, from the beginning of the flat piece method (Lichtenstein), to the later hernia plug plus flat piece, hernia device (PHS), kugel repair, more methods, is still improving, compared with the traditional surgery has a more desirable effect. However, the surgery destroys the anatomical structure of the inguinal canal, the patch and the inguinal canal surrounding tissue fusion adhesion, inevitably there will be some unique complications: 1, postoperative chronic pain accounted for about 10%, has attracted scholars at home and abroad attach great importance to the reason is that the surgery destroyed the anatomical structure of the inguinal canal, the operation of the unavoidable nerve damage, postoperative patch adhesion contracture pulling the nerves due to the reason, there is no good solution to the problem at present. There is no good solution to this problem. 2, the patch foreign body sensation is more common, hard piece, this feeling is more difficult. 3, wound infection: due to the large incision, patch superficial, this infection may be recent, may be a few months after the operation, and may eventually have to re-open to remove the patch. 4, more postoperative complications, such as redness and swelling of the scrotum, scrotal effusion and blood accumulation, orchitis, testicular pain, testicular atrophy. 5.Discomfort in sexual life, varicocele: caused by adhesion of the patch to the spermatic cord or jamming of the patch on the spermatic cord. 6, The latest issue of New England Journal of Medicine reported vasovaginal obstruction azoospermia due to adhesion of patch to spermatic cord, which is a new problem. Which is more advantageous, laparoscopic hernia repair or open tension-free hernia repair? Many large-sample, multicenter RCTs have been done both at home and abroad on this issue, and some of these trials have samples of more than 2,000 cases with more than 2 years of follow-up and a very convincing 95% follow-up rate. These trials have consistently demonstrated from the perspective of evidence-based medicine that laparoscopic hernia repair is absolutely superior to open tension-free hernia repair in terms of postoperative pain, length of hospitalization, return to daily life, work, and resumption of sports activities. From the principle of repair, laparoscopic hernia repair is a preperitoneal repair, which can most effectively restore the integrity of the transversal abdominal fascia, and utilize a large patch to cover the entire abdominal wall defect area including hiatal hernia, rectal hernia, femoral hernia, etc., so that repair is more complete and the recurrence rate is lower. In short, tension-free hernia repair to replace the traditional tension repair is an indisputable fact, laparoscopic hernia repair has a small trauma, fast recovery, light pain and other advantages undoubtedly, inevitably is the development trend of hernia repair is foreseeable. Inguinal hernia (commonly known as small intestinal gas or hernia) is formed due to the weak and defective tissues in the inguinal area, and the tissues or organs herniate out when the abdominal pressure increases. Hernia supports and hernia belts only provide temporary relief; surgical repair is the only radical cure. Traditional surgery, which has been performed for more than 100 years, is a self-tissue tension repair method, in which the muscles and ligaments around the defect are sewn together with thick threads during the abdominal wall repair. The disadvantages are that the incision is large, the patient will feel pain after the operation, and it is easy to recur. Moreover, the patient needs to stay in bed for 3 days after the operation, and will need to continue to rest after being discharged from the hospital after 3 weeks, and can only carry on a normal life after 3 months. Tension-free repair was proposed by American doctors in 1989 and is a “milestone” in hernia repair. It is characterized by avoiding the strong sutures of traditional surgery, repairing the defect through high-tech materials, less pain for the patient after surgery, low recurrence rate, and no need to stay in bed for 3 days. It is divided into: 1 open tension-free hernia repair, 2 laparoscopic hernia repair. So, what is better than the above two methods? Some scholars compare hernia repair to repairing a bucket with a hole in it. Open tension-free hernia repair is equivalent to patching up a piece on the outside of the bucket, and the pressure of the water in the bucket may wash away the patch on the outside, while laparoscopic hernia repair is equivalent to patching up a large piece on the inside of the bucket, and the pressure of the water in the bucket won’t wash away the patch and lead to recurrence. As the patient’s follow-up time increases, the thoroughness of laparoscopic hernia repair and the lower recurrence rate will be even more evident. Since 2004, our hospital has been the first to utilize laparoscopic technology for adult hernia repair, and has completed nearly 600 cases so far, which is the highest in the province, and the result is very satisfactory. Laparoscopic adult hernia repair is not like traditional surgery or open tension-free hernia repair that requires a large incision, no need to dissect the inguinal canal, no need to separate the spermatic cord, thus the inguinal canal and spermatic cord layers are not damaged, only 2 small 0.5cm incisions, 1 small 1cm poke holes can complete the surgery, recurrence rate <1%. The recurrence rate is <1%, which is far lower than the 10% of traditional surgery. It has the unique advantages of small trauma, fast recovery, small incision, postoperative aesthetic,; can detect the opposite side of the hidden hernia, and to be treated; an incision can be bilateral hernia repair, etc.; recurrent hernia is the only most effective treatment. Laparoscopic hernia repair has obvious advantages, the effect is certain, is the development trend of adult hernia repair. As the honorary president of Peking Union Medical College Hospital, Prof. Zhu said in the Third National Symposium on Hernia and Abdominal Wall Surgery, "Laparoscopic hernia repair in the 21st century has been widely used in foreign countries has been a precedent, and at home, with the improvement of the country's and the people's economic conditions, laparoscopic hernia repair will certainly become more and more popular for the adoption of the patient and the operator!
