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 minute and truly reaching “minimally invasive”. As a reminder, there are some so-called “minimally invasive and non-invasive cures for hernia without surgery”, which may be injection therapy. Blood lessons prove that this not only cannot cure 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, and local inflammation and scarring will occur after injection, adding difficulty and risk to future surgery, and injection therapy has long been no longer used in regular hospitals.
