What is minimally invasive surgery? Minimally invasive surgery refers to the surgical treatment of inguinal hernia using a laparoscopic approach. What are the advantages of minimally invasive surgery for inguinal hernia? 1. Basically no scar: When minimally invasive method is used to treat inguinal hernia, the scar that can be seen by the naked eye is only 3 mm, so it is difficult to find the scar with the naked eye, so it can be said that there is basically no scar. This can eliminate the psychological impact of scars on children, especially little girls. 2.It can deal with the “invisible hernia” on the opposite side. Because when a child has a unilateral inguinal hernia, it is possible that the contralateral side of the inguinal hernia is also not closed, but the intra-abdominal pressure is not enough to make it appear. Therefore, it is not possible to observe the closure of the contralateral internal ring orifice during traditional surgery, and there used to be cases where the hernia on the affected side resulted in the appearance of a hernia on the contralateral side. However, laparoscopy can avoid this situation, and if it is found that the contralateral internal ring is not closed, it can be operated at the same time, so that the child does not have to suffer another operation. 3. The trauma is small and the postoperative recovery must be faster. Therefore, we suggest that inguinal hernia in children should be treated with minimally invasive surgery if possible.
