What is a hernia? Or how does a hernia form? I often tell my patients that the human abdominal cavity is like a wooden barrel. Where is the most easily damaged part of the barrel? It is well known that it is the bottom of the barrel. Why? Of course, the bottom of the barrel is the most forceful! And in comparison to a human being? Of course it is the bilateral groin and pelvic floor. Bilateral groin has a spermatic cord and round ligament of the uterus through which there is a natural cleft. If you add to that the stunted, weakness of the area or the patient’s constipation, obesity, prostate enlargement, long-term coughing, qigong practice and other factors that increase abdominal pressure. A hole is formed in the inguinal area (from inside the abdominal cavity) and a swelling is seen from the groin, which is a reducible swelling. This is a hernia. The traditional method of repairing a barrel is to find a plug from the outside of the barrel bottom, that is, the bottom of the barrel to plug the hole and nail it with a wooden board. This is like a tension-free hernia repair. Its disadvantage is that the barrel is easy to fall off with the gravity of the water inside the barrel and the hole will recur after the plank is loosened. If a plank is added from the inside of the barrel, it will become more and more secure with the action of gravity. This is the advantage and rationale of transcatheter laparoscopic hernia repair. I hope that the majority of patients will listen and understand. We hope that patients will understand the reasoning behind it. Hernia can be classified according to the site of occurrence: inguinal hernia, umbilical hernia, and white line hernia. There are also incisional hernias and parastomal hernias that form as a result of surgery. Traditional inguinal hernia repair, in which the defect is repaired with its own tendon tissue. The main disadvantages are large incision, postoperative pain, high tension, high incidence of long-term postoperative pain, and weak tendon tissue (e.g., elderly people), and the biggest disadvantage of this procedure is that it is suspected of “tearing down the east wall to repair the west wall”, so the recurrence rate is high after surgery. In recent years, tension-free hernia repair for hernia has been gradually developed at home and abroad, which uses polymer material to repair the abdominal wall defect from the premises. This method solves the problem of long-term postoperative pain, but a small percentage of patients may experience a significant foreign body sensation, and a very small percentage of patients may experience rejection of the patch or infection, which may lead to long-term wound failure and even require a second operation to remove the patch. What is the advantage of laparoscopic inguinal hernia repair as a new type of surgery? This method is the most suitable surgical method for inguinal hernia anatomy, instead of “plugging” the defect from the outside in the first two ways, it adopts the way of “patching” the defect from inside the abdominal cavity in front of the transverse abdominal fascia. 1.Aesthetic wound with little damage; 2.Fast postoperative recovery and short hospital stay; 3.Low postoperative pain; 4.All kinds of unilateral and bilateral inguinal hernias (straight, oblique and femoral hernia) can be treated simultaneously with one method without increasing the incision; 5.Low complications, no scrotal edema and very little urinary retention; 6.No destruction of the natural structure of the inguinal region; 7.Conforming to the principle of tension-free repair, no long-term postoperative pain; 8. Low postoperative recurrence rate. Even no recurrence of hernia from the pubococcygeal muscle foramen at all. It is especially suitable for the treatment of recurrent hernia and incisional hernia, and is the best treatment for all kinds of hernias in the future. Of course, the cost of laparoscopic hernia repair is slightly higher compared to traditional surgery. Disadvantage: it is costly. It is not suitable for young people. Because the patch needs to be pressed against the spermatic cord. It is better for young people not to adapt. The average adult is fine. There will be no impact.
