Inguinal hernia is commonly known as “small intestine hernia”. Inguinal hernia is a common disease in children, with an incidence of about 1-4%, and up to 30% in premature babies. It is a congenital disorder and ranks first among all congenital disorders in children, with the contents of the hernia being the intestinal canal, the greater omentum and, in girls, the fallopian tubes or ovaries. If treatment is delayed, it can affect the child’s reproductive development; in cases of intussusception and strangulation, it can even endanger the child’s life. Hernia treatment has a history of hundreds of years, but as of today, surgery is still the only effective treatment. The two risk factors that trigger a hernia are increased abdominal pressure and a weak abdominal wall. When a child gets a hernia, it is like a new dress with unstitched threads, which can easily trigger a hernia when crying or strenuous exercise, mostly with just a stitch. “This disease has both congenital and genetic factors and has a genetic predisposition. Modified single-hole laparoscopic technique is the first in the country 3 mm small hole to solve the problem In the treatment of inguinal hernia in children, the hernia and abdominal wall surgery department of the hospital has been exploring, researching and summarizing in the treatment using laparoscopic technique, and the operation has developed from the original three-hole to two-hole and now single-hole, only one 3 to 5 mm poke hole and 1-2 1 mm needle eyes are needed to completely solve the hernia problem in children, and this technique is especially suitable for Children over 1 year old and under 7 years old, and the best time to operate is before the age of 3, because after the age of 3, when the child starts kindergarten, the child’s movement increases, which accelerates the development of the hernia. Single-port laparoscopy is much less invasive, leaving no scars after surgery, and the procedure takes only 5 to 10 minutes. This technique has been clinically used in more than 500 cases in hospitals and is very popular. However, there are certain operational difficulties due to one-handed operation, and with the self-invented clamp needle, it is possible to complete high-grade ligation of hernia sacs in children under single-port laparoscopy, breaking the single-port laparoscopic method that has languished for several years and has not been promoted. For older children with inguinal hernia between the ages of 7 and 18 years, the surgical method has also been improved by applying a biopatch of decellularized matrix material to perform the surgery, allowing the repair of the inguinal region in older children while performing high ligation of the hernia sac, further reducing the chance of postoperative recurrence, and the biopatch can be completely degraded and absorbed without creating a foreign body to the body. The bio-patch can be completely degraded and absorbed without any foreign body effects on the human body and will not have any effect on the growth and development of the child. At present, the method and concept of inguinal hernia repair in adolescents using biopatch has been widely recognized by experts both at home and abroad. What is a hernia? A hernia is when a part of the body’s tissue or organ leaves its original site and enters another site through a gap, defect or weakness in the body. Among them, inguinal hernia is the most common. The hernia itself is not particularly symptomatic and may be a little sore and swollen. Some may find a soft bulge in the groin or scrotal area that becomes smaller or disappears when lying on one’s back. The mass increases in size when coughing, bending over, carrying things, or exerting force. Because these symptoms are not obvious, they also rarely attract attention.
