A hernia is when a part of the body’s tissue or organ leaves its original site and enters another site through a gap, defect or weakness in the body. It is commonly known as “small intestine gas”. There are many types of hernias, including inguinal hernia, inguinal hernia, femoral hernia, incisional hernia, etc. Most of the hernias are caused by increased pressure inside the abdominal cavity (chronic cough, constipation, difficulty in urination due to prostate enlargement, etc.) or by local weakness of the abdominal wall. The typical clinical manifestation of a hernia is a localized protruding mass, which appears when standing, walking, coughing or working, and disappears in a lying position or by pushing the mass with the hand to bring it back into the abdominal cavity. As mentioned above, Mr. Li’s symptoms are typical clinical manifestations of inguinal hernia. As a common disease, inguinal hernia has a high incidence among middle-aged and elderly people. In particular, inguinal hernia is the most common. Many patients think that this is a minor disease and are reluctant to consult a doctor, but this view is actually wrong. Once the contents of the hernia are trapped by the hernia ring and cannot be retracted, it will cause ischemic necrosis of the trapped contents, resulting in acute symptoms such as abdominal pain, nausea and vomiting, fever, etc. It is clinically called an incarcerated hernia. Therefore, the danger of hernia should not be underestimated and should be treated actively after it is found. Surgery is the most effective way to treat hernias. The earliest surgical method was to repair the defect by directly suturing the abdominal wall tissue, which is rarely used due to its high recurrence rate and local discomfort after surgery. Tension-free hernia repair is now widely used. This involves repairing the defect with a patch made of artificial material, similar to a patch on a garment. This removes tension from the suture, thus avoiding postoperative discomfort. Moreover, the recurrence rate after tension-free hernia repair surgery is extremely low and can significantly improve the patient’s quality of life. In recent years, laparoscopic surgery has also become a new approach to hernia treatment. With the help of laparoscopic instruments, a few small holes of one or two centimeters are made in the abdominal wall, into which a camera and special surgical instruments are inserted, and the camera shows the images of the operated area directly on the screen, the same as a live sports game on TV. The surgeon can do the surgery directly on the screen under direct vision, which makes the surgery simple, less invasive and quicker to recover. Patients are able to resume their daily activities soon after surgery and can be discharged from the hospital in 2-3 days after surgery. The change is obvious compared to the traditional surgery that required lying down after surgery and 3-5 days to get up and move around. Moreover, only a few small traces of holes are left in the surgical area after surgery, which are not obvious unless you look closely, and the traditional long surgical scars have disappeared. Because of these significant advantages, laparoscopic hernia surgery is widely accepted by patients and physicians, and is developing more and more rapidly, and has now become an important means of hernia surgery treatment at home and abroad.
