The surgical methods for pediatric hernia are mainly divided into the traditional open surgery and the current laparoscopic surgery. Laparoscopic surgery is a kind of minimally invasive surgery. As the concept of minimally invasive gradually gains popularity, the technology of laparoscopic surgery for pediatric hernia has become more and more advanced, progressing from the three-hole method (three holes are made in the child’s belly), to the two-hole method, to single-site surgery via the umbilicus, to the scarless surgery we now do for pediatric hernia, and in the future, to pneumoperitoneum-free laparoscopic surgery, making the trauma more and more tiny and truly reaching “minimally invasive”. Minimally invasive is a philosophy of making trauma continuously more and more tiny. Currently, pediatric laparoscopic techniques are the technical means to achieve this philosophy. Therefore, minimally invasive is relative. Compared to open surgery, laparoscopic techniques may be more minimally invasive; compared to traditional laparoscopic techniques, atraumatic surgery may be more minimally invasive; and as medicine advances, more minimally invasive techniques may emerge. However, each technique has its own limitations, and it is not possible to generalize which surgical procedure is absolutely the best, taking into account the specific condition of the child and the medical conditions of the local hospital. At present, the majority of pediatric hernias are suitable for treatment through laparoscopic surgery. In China, the two-hole method is commonly used for surgery – a 5mm laparoscope is placed in the umbilicus, another 5mm diameter instrument is placed in the abdominal wall, and a hernia needle is disposed in the groin to complete the high ligation of the hernia sac. As a reminder, some of the so-called “minimally invasive and non-invasive cure for hernia without incision” may be injection therapy. Blood lessons have proved that this not only cannot cure the hernia, but also can cause serious consequences such as abdominal adhesions, intestinal obstruction, spermatic cord vascular occlusion, vas deferens damage, and even loss of fertility, etc. Moreover, local inflammation and scarring will occur after injection, which will make future surgery more difficult and risky, and injection therapy has long been discontinued in regular hospitals.
