Inguinal hernia is a hernia formed by the protrusion of intra-abdominal organs to the body surface through the defect in the inguinal region, commonly known as “hernia”. There are two types of inguinal hernias: inguinal hernia and inguinal hernia. There are two types of inguinal hernias: congenital and acquired. It is more common on the right side than on the left side, and the ratio of male to female incidence is 15:1. If left untreated, it can easily lead to serious complications. The main cause of inguinal hernia is the decrease in muscle strength of the abdominal wall and the increase in intra-abdominal pressure. Muscle atrophy in the elderly makes the abdominal wall weak, and the inguinal region is even weaker, with blood vessels, spermatic cords or round ligaments of the uterus passing through it, giving access to the formation of hernias. In addition, diseases such as coughing and asthma, constipation and difficulty in urination due to prostatic hyperplasia in the elderly cause an increase in abdominal pressure, which provides an impetus for the formation of hernias. Clinical manifestations 1. reducible hernia is characterized by a reducible mass in the inguinal region, which is small at first and appears only when the patient is standing, working, walking, running, coughing or crying. 2. sliding hiatal hernia is characterized by a large and difficult to reducible hernia that cannot be completely retracted. The cecum that slides out of the abdominal cavity often adheres to the anterior wall of the hernia sac. In addition to the incomplete retraction of the mass, there are also symptoms such as dyspepsia and constipation. Sliding hernias are mostly seen on the right side, and the ratio of incidence between the left and right sides is about 1:6. 3. Intrusive hernias often occur when there is a sudden increase in intra-abdominal pressure such as labor or defecation, and are usually hiatal hernias. The clinical features are a sudden increase in the size of the hernia mass with significant pain. The mass cannot be retracted by lying down or pushing it by hand. The mass is tense and hard, and there is significant tenderness. Once the hernia is embedded, the above symptoms gradually worsen, and if not treated in time, it will eventually become a strangulated hernia.4 The clinical symptoms of strangulated hernia are more severe, and patients have persistent severe abdominal pain, frequent vomiting, vomit containing coffee-like blood or bloody stool; abdominal signs are asymmetric abdominal distension, with signs of peritoneal irritation and diminished or absent bowel sounds; abdominal puncture or lavage is a bloody fluid; X-ray examination shows isolated distended intestinal mix or tumor-like shadows; temperature, pulse, and blood pressure are all present. X-ray examination shows isolated distended intestinal mix or tumor-like shadow; body temperature, pulse rate, white blood cell count gradually increases, and even signs of shock.
