Pediatric inguinal hernia, commonly known as hernia or small intestine detachment, can develop in both sexes, but is more common in boys. The minimally invasive pediatric laparoscopic surgery carried out by our department has been well received by children and parents. Compared with traditional open surgery, laparoscopic minimally invasive surgery has the following advantages: 1. Minimally invasive small incision, only 0.3-0.5cm. 2. Significantly shorter hospitalization time. 3. Good cosmetic effect, small postoperative scars. 4. 4.Less pain and quick recovery. 5.Basically no bleeding. 6.The hernia on both sides can be treated at one time, avoiding another additional incision. 7.Minimally invasive damage, not through the inguinal canal, so its anatomical structure is not destroyed.
