Hernia is a common and frequent disease. The etiology is thought to be due to the thinness of the transversal abdominal fascia in the inguinal region of the body. Currently, the mainstay of inguinal hernia treatment is patch repair surgery, and patients are faced with the choice between open surgery and minimally invasive-laparoscopic surgery. So what is the difference between the two surgical methods? I will give you a brief explanation and explanation of this question. First of all, both surgeries require the use of a patch, which is common, and the overall statistical results for the treatment of hernias are roughly the same. But there is a big difference between the two in terms of treatment philosophy. Open surgery, which is the anterior approach, is done openly, with layers of incised skin and tissue, finding and treating the hernia sac, and using a patch to repair the thin transverse abdominal fascia. The emphasis is on repair, and there are many open surgical approaches that are currently designed with the idea of covering a larger area of the pubococcygeal foramen area for the purpose of treating and preventing the occurrence of hernias, but the actual results are limited. This type of surgery is currently performed by us using local anesthesia, and the indications for surgery are very broad, especially when the elderly and frail and chronically ill patients are involved. Laparoscopic surgery is a posterior approach, whether TAPP or TEP, which involves entering the anterior peritoneal space, treating the hernia sac and then using a 10*14CM patch to cover the entire pubococcygeal foramen area, replacing the thin transversus abdominis fascia, with the aim of completely preventing recurrence or reoccurrence in addition to treating the hernia. Since the patch is mostly a three-dimensional anatomical structure, the postoperative comfort is excellent and the foreign body sensation is very low. Theoretically, laparoscopic surgical hernia repair can reduce recurrence to 0. Laparoscopic surgery also has the disadvantage that larger hernias tend to form effusion after surgery due to the emptiness of the defective area, but there is no need to worry, as most of this condition will absorb on its own, but it is only more likely to occur compared to open surgery, as the surgery is a posterior approach to transversus abdominis fascia replacement therapy, which does not require attention to the weak area. The two methods, one is repair and the other is replacement, each has its own advantages and features. Although both use patches, the principles of patch form and purpose of use are different.
