Hernia is a multiple disease, especially among children and middle-aged and elderly people who suffer from hernia is very high, according to relevant data: there are about 20 million cases of inguinal hernia patients worldwide every year. The general incidence of hernia is 1~4%, 15 times more in men than in women. In China, the elderly population is more than 300 million, the incidence of hernia in the population over 60 years old is 1.18%, and the number of elderly hernia patients is about 5.4 million, so there are still millions of hernia patients suffering from pain in China. 1. What is inguinal hernia: We call a hernia that occurs in the inguinal region an inguinal hernia, which includes hiatal hernia, straight hernia and femoral hernia. Any organ or tissue that leaves its original site and enters another part of the body through a normal or abnormal weak point or defect or orifice is called a hernia. The most common hernia is extra-abdominal hernia, which includes inguinal hernia and abdominal wall hernia (umbilical hernia, incisional hernia, white line hernia, etc.), 95% of which is inguinal hernia, one of the most common diseases in surgery. 2.What causes inguinal hernia: The causes of hernia are two factors: decrease in strength of abdominal wall and increase in intra-abdominal pressure. Elderly people often suffer from chronic bronchitis, hypertrophy of the prostate gland, habitual constipation and other diseases; long-term chronic cough, difficulty in urination and straining to defecate, resulting in increased intra-abdominal pressure. In addition, the degeneration of the abdominal wall muscles and tendons in the elderly and the decrease in strength, coupled with obesity or long-term illness in bed and other factors, can easily lead to atrophy of the abdominal wall muscles and hernia. What are the symptoms of inguinal hernia: When you find a lump at the root of your thigh or near your abdominal femoral area, which may disappear when lying down, and may occasionally feel painful and uncomfortable, and may worsen when exercising, you may have a hernia and should see a doctor as soon as possible. Within a year after birth, parents can see or feel a significantly enlarged swelling in the scrotum of these young infants, and light pressure on the swelling with a finger can make it return to the abdominal cavity. This is an infant hernia. 4. Why does a hernia hurt: When you have a hernia , you will feel uncomfortable, especially when coughing, lifting heavy objects or standing for a long time. This is because the tissues in the body are pushed into the weak point under a certain amount of pressure, and the pressure increases as more tissue is pushed into the weak area of the abdominal wall to feel pain. When the hernia develops further and worsens, you will feel severe pain. 5. What are the hazards of hernia: (1) in mild cases, there is a local lump with occasional distension and pain, which gradually increases in size and affects normal movement; (2) in severe cases, it leads to incarcerated hernia, which may be accompanied by abdominal cramps, nausea, vomiting, constipation and abdominal distension; (3) if not treated in time, part of the protruding small intestine may lead to necrosis due to the cessation of blood flow; (4) in more serious cases, it may lead to infection and cause sepsis, which is life-threatening (4) more serious cases may lead to infection, causing sepsis and life-threatening. Therefore, except for a few special cases, hernias should be surgically repaired as soon as possible. 6. What to do if you have a hernia: The onset of hernia is more common in children and the elderly, and inguinal hernia is common in male patients. Femoral hernia usually occurs in the upper thigh and is common in women. Except for a few special cases, hernias should be repaired surgically as soon as possible. Because the inguinal canal is not occluded until 6 months after birth, it is possible for an infant hernia to heal spontaneously within 6 months of age. However, if the hernia does not disappear or tends to increase in size after one year of age, it is unlikely to heal on its own. Therefore, surgery should be considered for hernia in infants over 6 months of age. 7. Can a hernia heal itself: A hernia cannot heal itself. Patients with early or mild symptoms may feel pain, lower abdominal swelling, indigestion and diarrhea. After the disease develops, the lump will fall into the scrotum, causing inconvenience in activities and walking. In severe cases, it can cause impaction, which can lead to intestinal necrosis and even life-threatening if not treated in time, and the only way to completely treat this disease is surgical treatment. 8. How to treat hernia: The only way to cure “hernia” is surgical treatment. At present, our hospital uses tension-free hernia repair under local anesthesia, which has a small incision, little damage to the patient, small stripping surface, and belongs to the category of minimally invasive surgery, without suture tension and without destroying the normal anatomical structure. This treatment is simple, fast, with few complications and little patient pain, and can quickly resume normal physical activities. The patient can be discharged after 2 to 3 days of hospitalization and resume normal physical activities after one week, and the recurrence rate after surgery is <1%, which greatly improves the quality of life of the patient. The synthetic material implanted fully conforms to the eight standards of the World Health Organization recognized implant materials. 9. What should be noted before and after the surgery of tension-free hernia: Most doctors only do some routine routine examination as requested before the surgery of tension-free hernia; no enema is needed before the surgery; no urinary catheter is needed. You can eat and get out of bed after 6 hours of surgery. No prolonged lying down is required. Postoperative anti-inflammatory 1-2 days, no need to remove stitches, and you can be discharged from the hospital 3 to 4 days after surgery. Those who work lightly can return to normal work in 1 to 2 weeks; for those who work heavily, a slightly longer recovery time is needed. Outpatient review 1 week and 1 month after surgery.
