Inguinal hernias include hiatal, ventral and femoral hernias that occur in the inguinal region, and surgery is the only ultimate method to cure them. Surgical treatment of hernias has a history of more than 100 years, and according to statistics there are more than 80 surgical methods, most of which have now been eliminated and less than ten are commonly used in clinical practice. The cost of completing a hernia surgery ranges from about $1,000 to $6,000 or $7,000, so how to choose a reasonable cost and get a good treatment is a question that many patients often encounter. The advantage of traditional hernia repair is that it is more economical, such as surgery under local anesthesia, and the cost is about one thousand dollars, and the commonly used method is Bissini repair. However, traditional surgery has disadvantages. One is that the postoperative pain is longer because the muscles around the defect have to be forcibly sewn up, which results in high local tension, and some patients cannot even straighten up after surgery; the second is that the postoperative recovery time is long; the third is that the recurrence rate is as high as 10%-15%, especially in the elderly, and the recurrence rate is even higher, so traditional surgery is generally not given priority in areas or patients with conditions. The other category is tension-free hernia repair, which was introduced in the 1960s and became the main means of hernia surgical treatment after the 1980s when it became widely popular. A tension-free hernia repair is the repair of a defect in the abdominal wall with an artificial material, just as we would use a good piece of cloth to patch a hole in a garment. The more commonly used repair materials are polypropylene, polyester and other polymer materials. These materials have good tissue compatibility in the human body. Tension-free hernia repair was first performed in China in 1994 and has rapidly spread throughout the country since 1997. One of the greatest advantages of this tension-free hernia repair is the low recurrence rate, which is generally recognized as less than 2%, as well as the advantages of light postoperative pain and short recovery time. Nowadays, about 500,000 such surgeries are performed in China every year, and the results have been proved to be good. (1) Tension-free repair with flat piece: This procedure is more common in foreign countries but less used in China, with the advantage that it is more economical. (2) Tension-free hernia ring filling repair method: This procedure was introduced in China in 1997 and is widely carried out in the country. Because of the expensive plugs used, the cost of outpatient local anesthesia surgery is about three thousand to three thousand five hundred. (3) Priligy three-in-one tension-free hernia repair method: This procedure is performed with a stereotyped product (UHS) manufactured by Johnson & Johnson, which consists of three parts: a bottom piece placed in front of the peritoneum to repair the pubococcygeal muscle hole; a plug-like intermediate to repair the hernia ring; and a surface piece to repair the posterior wall of the inguinal canal. The cost of outpatient local anesthesia surgery is about six thousand. (4) Laparoscopic inguinal hernia repair: Ger first performed laparoscopic inguinal hernia repair in 1982 with success. With the gradual increase in clinical reports, the repair methods have diversified, and laparoscopic inguinal hernia repair has some special advantages such as one-stage repair of two-sided hernia and recurrent hernia repair again, which reduces the difficulty of surgery but requires better technique of the operator. The surgery is usually performed under general anesthesia or epidural anesthesia and the cost of applying common materials is usually around eight thousand, sometimes even more. The cost of an atonic hernia repair varies mainly due to the materials used, the type of anesthesia used and the adjuvant medication used after the surgery, but there is no major difference in postoperative recovery between the different surgical approaches as long as the surgery is done properly. Since tension-free hernia repair requires the use of artificial materials, some materialogenic complications such as chronic infection and intestinal fistula have occurred after the use of early materials, so recently there has been a general shift to light-weight large mesh patches. For underdeveloped areas, the traditional tension repair is still available. Currently, it is mostly advocated to specialize hernia surgery and have the surgery done by specialized hernia surgeons, so that the surgical complications will be reduced.
