Patients with inguinal hernia are commonly seen in pediatric and elderly patients. The former are congenital and surgery is mostly advocated after the age of 1 year because some patients can heal on their own with their own development. In the elderly, the hernia is caused by the weakness of the abdominal wall, together with chronic constipation, prostate enlargement, chronic bronchitis and other triggers, and it is impossible to heal by itself. How to treat reasonably is the key. 1. Some small or asymptomatic hernias that do not enter the scrotum can be observed. 2. For symptomatic hernia, surgery should be performed as soon as possible if the physical condition allows, i.e. there is no contraindication for surgery. Surgery is the only method that can cure the hernia completely. Currently, open surgery and laparoscopic surgery are commonly used. We cannot simply compare which one is better, only the one that suits us can be said to be the best. 4. Open tension-free repair surgery is currently the mainstream surgical method and is suitable for the treatment of all kinds of hernias. The incision is usually about 5 cm, local anesthesia is available, and synthetic patches of different shapes are placed during the surgery according to the type of hernia, which is ideal for people of advanced age and with concomitant diseases. 5, laparoscopic surgery is done through laparoscopic technology, accounting for 15-20% of the surgery volume in Europe and the United States, and slightly lower in our country. It is more suitable for young patients, patients with bilateral hernia, patients with recurrence after partial anterior approach surgery and patients with requirements in this regard. It is not suitable for elderly patients with chronic lung disease and patients who cannot interrupt their medication because they are fasting before and after surgery. Laparoscopic surgery patients have low incisional complications and faster recovery, but the cost is higher, 1/3~1/2 higher than open surgery. 6. Currently, some hospitals apply minimally invasive techniques to treat inguinal hernia with local injection of a kind of adhesive gel. This treatment is unscientific and is not carried out in regular large hospitals in our country, including Beijing and Shanghai. The hernia occurs because of the weakness of the abdominal wall, and what needs to be strengthened or repaired during surgery is the area of 7-10 cm in diameter, not simply a small hole that can be glued, and this means should not be applied even in patients with small defects, and it is difficult to guarantee for doctors with thousands of cases of surgical experience to inject directly into the hernia ring opening. The injection can cause local hardness, adhesions, edema, pain, and even serious complications of intestinal canal damage. The injection treatment makes subsequent surgery very difficult and complications after surgery are significantly increased. Experts at the National Specialty Conference on Hernia and Abdominal Wall Surgery agreed that this is a treatment method that should be eliminated.
