Hernia is a kind of multiple diseases, especially children and middle-aged and elderly people suffer from hernia very much, according to the relevant data: there are about 20 million cases of inguinal hernia patients every year in the world. The general incidence of hernia is 1-4%, men are 15 times more than women, in China, the elderly population of more than 300 million, the incidence of hernia in the population over 60 years of age is 1.18%, the elderly hernia patients are about 5.4 million, so there are still millions of hernia patients in China are enduring the pain. 1, what is inguinal hernia: we will occur in the inguinal region of the hernia called inguinal hernia, it includes oblique hernia, straight hernia and femoral hernia. Any organ or tissue that leaves its original location and enters another part of the body through a normal or abnormal weak point or defect or orifice in the body is called a hernia. The most common hernia is an extra-abdominal hernia, 95% of which are inguinal hernias, which are one of the most common diseases in surgery. 2, what causes inguinal hernia: the cause of hernia is the abdominal wall strength reduction and intra-abdominal pressure increase two factors. Elderly people often suffer from chronic bronchitis, prostate hyperplasia and hypertrophy, habitual constipation and other diseases; long-term chronic cough, urinary difficulties, defecation effort, resulting in increased intra-abdominal pressure, crowding, compression of abdominal organs to the abdominal wall weak area displacement. In addition, ascites caused by cardiopulmonary and liver diseases will also slowly cause an increase in abdominal pressure. The elderly abdominal wall muscle, tendon degeneration, strength is reduced, coupled with obesity or long-term illness bedridden factors, is very likely to lead to abdominal wall muscle atrophy and hernia. 3, what people are prone to hernia: According to incomplete statistics, China has about a million hernia patients. Inguinal hernia is common in male patients, the main reason is due to the abdominal wall defects in the posterior wall of the inguinal canal, intestinal loops from this bulging, forming a hernia block, which can be descended to the scrotum. Femoral hernias usually occur in the upper thigh and are common in women. In China, with an elderly population of more than 300 million, the incidence of hernias in people over the age of 60 is 1.18%. Medical experts believe that there are still thousands of people enduring the pain of hernia. 4, what are the symptoms of inguinal hernia: hernia can be seen or can be felt. When you find a lump appearing at the base of the thigh or near the abdominal-femoral area, which may disappear when you lie down, and occasionally you may feel pain and discomfort, which can be aggravated by exercise, you may have a hernia, and you should see a doctor as soon as possible. Within a year after the child is born, parents can see or feel the scrotum of these small infants significantly enlarged with a swelling, with a finger to gently pressure the swelling can make it return to the abdominal cavity. This is a baby hernia. 5, why hernia will be painful: when suffering from a hernia , you will feel uncomfortable, especially when coughing, lifting heavy objects or standing for a long time. This is due to the fact that the tissues in your body are pushed into the weak point under certain pressure, and you feel pain when the pressure increases as more tissues are pushed into the weak area of the abdominal wall. When the hernia develops further and worsens, you feel severe pain. 6, what are the dangers of hernia: light in the local mass, occasional swelling and pain; heavy can be accompanied by abdominal cramps, nausea, vomiting, constipation, abdominal distension and other symptoms; if not treated in time, part of the protruding small intestine will be due to the cessation of blood flow and lead to bad; the more serious cases will lead to infection, resulting in sepsis, life-threatening. Therefore, in addition to a few special circumstances, hernia should be early surgical repair. 7, got a hernia how to do: hernia incidence to children and the elderly, and to the male patients mostly. Elderly patients at the beginning of the abdominal wall appeared a should not have a mass, and lying down after the disappearance of this situation is almost certain to be hernia, hernia patients light in the local mass, occasional distension and pain, the heavy can be accompanied by abdominal cramps, nausea, vomiting, constipation, abdominal distension, and other symptoms, such as timely treatment, part of the protruding small intestine will be due to the cessation of blood transportation and lead to necrosis, the serious case will lead to infection, resulting in sepsis, a threat to life. Life-threatening. Therefore, except for a few special cases, hernia should be surgically repaired as soon as possible. Because the inguinal canal of infants does not become atretic until 6 months after birth, it is possible for infant hernias to heal on their own within 6 months. However, if the hernia does not disappear or tends to increase in size after the age of one year, it is unlikely to heal spontaneously. Therefore, surgery should be considered for hernias in infants over 6 months of age. 8. Can hernia heal by itself: Hernias cannot heal by themselves, although they do not get worse within a short period of time. Early or mild symptoms patients may feel pain, lower abdominal swelling, indigestion, diarrhea and so on. As the disease progresses, it can cause difficulty in mobility and walking as the mass falls into the scrotum. In severe cases, it will cause incarceration, if not treated in time, it will cause intestinal necrosis, even life-threatening, and the only way to completely treat this disease is surgical treatment. 9, how to treat: the only way to cure “hernia” is surgical treatment. Therefore, patients with hernia should go to the regular hospital for surgical treatment. Surgical treatment can be divided into traditional surgical treatment and tension-free hernia repair. Traditional surgical treatment due to the “lack of hole” between the tissues have a certain distance, forced suture, the tension caused by the easy to cause severe pain and recurrence after surgery, recurrence rate of 10-15%. After surgery, patients need to stay in bed for three days, rest for three weeks after discharge, and cannot participate in heavy labor for three months. Therefore, traditional surgery has been gradually eliminated. At present, many hospitals use tension-free hernia repair, small incision, small damage to the patient, small stripping surface, belongs to the category of minimally invasive surgery, there is no suture tension, does not destroy the normal anatomical structure. This treatment method is simple, fast, few complications, patients with little pain, can quickly return to normal physical activities, three days after the operation can be discharged from the hospital, one week after the return to normal physical activities, postoperative recurrence rate <1%, greatly improving the quality of life of patients. The implanted synthetic material is currently recognized by the World Health Organization as the only biological implant material that meets the eight criteria for implant materials. Therefore, the majority of hernia patients should remove the fear of surgery, go to the hospital in time to receive surgical treatment. 10, tension-free hernia surgery before and after what should be noted: most of the tension-free hernia surgery can be completed under local anesthesia, so the doctor before the operation only according to the request to do some routine routine examination; no need to cure the disease caused by increased abdominal pressure; local anesthesia surgery without fasting water; no enema; no need to go down the urinary catheter. Local anesthesia surgery can eat after surgery. No need to lie down for three days, no need to press the incision. Young patients without underlying diseases can get out of bed after surgery, but it is recommended to stay in bed for 1-2 days without restricting activities. Postoperative anti-inflammatory for 2-3 days, no need to remove stitches, and can be discharged 2-3 days after surgery. With traditional surgical treatment, it takes months or even half a year for patients to return to normal work. Tension-free hernia repair surgery solves this problem, usually patients only need to rest for a few days, light manual laborers can return to normal work in 1-2 weeks; heavy manual laborers, it will take a little longer to recover. The first week after surgery and 1 month outpatient review 11, laparoscopic hernia repair Laparoscopic hernia repair is the development of tension-free repair in recent years. In this method, a hernia patch is placed behind the inguinal "gap" laparoscopically to strengthen the posterior wall of the inguinal canal. Since the patch is placed in the deepest part of the groin, this approach minimizes postoperative recurrence. Laparoscopic inguinal hernia repair has the advantages of mild pain, small incision, early return to activity, and no surgical scar in the inguinal area after surgery, but has the disadvantages of requiring general anesthesia and high cost. Laparoscopic hernia repair is most advantageous for bilateral hernia and recurrent hernia.
