Inguinal hernia is mostly seen in boys, but it is also common in girls. In boys, the hernia contents are mostly small intestine, while in girls, in addition to small intestine, ovaries and fallopian tubes are also common. We know that pediatric hiatal hernia is often embedded during crying and coughing with pneumonia, and the contents of the hernia will occur over time, so little girls should pay more attention to it, otherwise it will cause ovarian necrosis and affect the fertility and endocrine function of the child in the future. In addition, when operating on a hiatal hernia in a young girl, the fallopian tube should be beware of becoming part of the hernia sac (i.e., a slip hernia), and care should be taken not to ligate the fallopian tube while ligating the hernia sac neck, which should be treated as a slip hernia operation. At the same time, the external ring can be closed to prevent recurrence (boys with spermatic cord passing through cannot be closed). In young girls, if the hiatal hernia protrudes repeatedly, the chances of forming a hiatal hernia increase, so once diagnosed, surgery should be performed as early as possible if local medical technology and medical conditions are reliable. Nowadays, many physicians recommend surgery after 6 months of age, taking into account the tolerance of pediatric surgery and anesthesia safety. In fact, in clinical practice, many children are operated before 6 months of age due to a variety of reasons and the inability to reset. Therefore, I personally think that the concept of our clinicians should also change with the progress of medicine, so as not to let the parents of the children in the long wait in fear, but to improve the level of our medical staff for the surgical treatment of newborns and children less than 6 months.
