Although hernia surgery is not major, it is not a “minor” surgery that can be taken lightly, but a surgery that should be “opened carefully”. Possible complications include testicular ischemia and atrophy, vas deferens damage, recurrence, hematoma, infection, chronic pain, bladder injury, bowel injury, etc. Recurrence and complication rates between hernia specialists and general surgeons have been reported from around the world. The recurrence rate of tension-free repair surgery performed by a hernia specialist is around 0.1%, while the recurrence rate of surgery performed by a surgeon who is not a hernia specialist can be up to 5%. Therefore, it is important to find a hernia specialist who is experienced in hernia surgery. The essence of a hernia is a physical defect of the abdominal wall, and therefore, only surgery can cure it. There are dozens of mainstream hernia repair surgical methods in clinical use, which one is the best? The international authority says that there is no one surgical method that is best, but only the one that is most suitable for the specific condition of the patient, i.e. the individualized surgical plan, including the specific anesthesia, surgery and repair material. For the surgeon, it is best to use the best surgical approach, which can shorten the operation time and reduce complications. Currently, there are dozens of surgical procedures in the following three main categories: 1. Traditional tension hernia repair: slightly more traumatic, longer postoperative recovery time, higher chronic pain rate and recurrence rate, and only for a few patients with special conditions. 2. Tension-free mesh hernia repair: it accounts for more than 80% of all types of hernia repair, and the recurrence rate is much lower than that of traditional hernia repair, which is the mainstream surgical procedure at present. 3.The patient’s abdominal cavity. A patch is placed into the patient’s abdominal cavity or the preperitoneal space with the help of a camera. The surgeon performs the procedure through imaging on a television screen. This type of surgery has good recent results, but is more expensive and has the potential for rare and serious complications such as internal organ damage and large vessel damage. This type of surgery is more suitable for patients with bilateral hernias of short duration or for patients with partial recurrent hernias. Depending on the surgeon’s experience and skill level, the recurrence rate of hernia after laparoscopic repair ranges from 0.5% to 11%.
