Inguinal hernia, commonly known as small intestine pneumonia, is a common surgical condition, especially among children and the middle-aged and elderly population. A hernia occurs when some organ or tissue of the body (mostly the small intestine) leaves its original site and enters another site through a weakness or defect. Hernias occur most often in the abdomen, with inguinal hernias being the most common. There are many causes of inguinal hernias, mainly reduced abdominal strength and increased intra-abdominal pressure. Muscle atrophy and weakness of the abdominal wall in the elderly, and even more weakness in the inguinal region, combined with the presence of blood vessels, spermatic cord or round ligament of the uterus passing through, give access to the formation of hernias. In addition, elderly people tend to have coughing and asthma, constipation, and difficulty in urination due to prostate enlargement, resulting in increased abdominal pressure, which provides the impetus for hernia formation. If a reversible mass appears in the inguinal region (that is, the root of the thigh), i.e., it appears when standing, walking, coughing, or working and disappears when resting flat, the possibility of inguinal hernia should be considered. Currently, many people have misconceptions about the treatment of inguinal hernia, thinking that it is not life-threatening, so they think it can be treated or not. Older people are especially reluctant to undergo surgery, fearing anesthesia, etc. However, once an inguinal hernia becomes lodged and cannot be retracted, it can lead to intestinal obstruction and even intestinal necrosis and perforation, which can be life-threatening. Conservative treatment of inguinal hernia includes hernia belt, hernia brace, Chinese medicine, herbal medicine and injection therapy, etc. These methods can relieve symptoms or delay the development of the disease, but cannot cure it. Some people who are temporarily inoperable due to the combination of other serious diseases can also be treated conservatively first. Surgery is the only reliable way to cure inguinal hernia. Traditional surgery involves repairing the defect by suturing the tendon membrane and ligament around the defect, which has the disadvantages of high recurrence rate, high tension, postoperative pain, and limitation of movement.
