Pediatric surgeons generally believe that the optimal age for surgery for inguinal hernia is more than half a year old. However, in the past clinical work, it was found that children with inguinal hernia under half a year old, if often incarcerated, the age of surgery may not be able to wait until half a year old, most of the children usually occur within half a year of the incarcerated hernia and need emergency surgery, and even incarcerated necrosis of the intestinal tube, resulting in intestinal resection and anastomosis. New textbooks have now clarified that only inguinal hernias can be treated surgically once diagnosed, regardless of age. Although the younger the patient is, the more difficult the operation becomes, these difficult operations are not a problem for an experienced pediatric surgeon. The decrease in age at surgery also provides a significant reduction in the chance that the child will have an incarcerated inguinal hernia resulting in necrosis of the bowel. From the point of view of disease progression, it is recommended that inguinal hernias be treated surgically as early as possible after diagnosis. First, inguinal hernia incarceration leading to intestinal necrosis can be reduced. Secondly, an incarcerated inguinal hernia can compress the blood vessels of the spermatic cord, causing necrosis of the testis or epididymis, which can lead to the possibility of infertility. Therefore, it is safe to operate on inguinal hernia in children less than 3 months old. There are two types of surgeries: First, general surgery, which is a high hernia sac ligation with an incision in the groin. Secondly, laparoscopic internal ring closure. The procedure involves making three 0.5cm incisions in the abdomen and performing the surgery laparoscopically. The above two surgical methods have their own advantages. You can consider them on your own.
