Pediatric inguinal hernia is a common surgical condition that, if left untreated, can lead to hernia impaction, intestinal perforation, and in severe cases, may cause permanent dysfunction and seriously affect the function of the reproductive system. At present, laparoscopic surgery is the preferred surgical procedure for inguinal hernia, with the characteristics of less trauma and shorter recovery time. During the embryonic period, there is a “peritoneal sheath” in the groin. In some children, this sheath closes incompletely after birth, causing the small intestine, omentum, ovaries, fallopian tubes, etc. to enter this sheath, which becomes a hernia. Most of the time, a protrusion is formed in the groin, especially when the child cries and strains, such as when the child defecates. However, there are cases where the bulge is not obvious or even invisible. If the hernia is not treated in time, the protrusion may get stuck in the intestinal wall of the child. If the protrusion is not reset in time, insufficient blood supply may occur, resulting in hernia impaction and intestinal perforation, which may cause permanent dysfunction in serious cases. The hernia may also cause insufficient blood supply to the ipsilateral testicle, leading to atrophy. In girls, the hernia protrusion usually wraps around one ovary, which can lead to ischemic necrosis of the ovary if left untreated. It even affects the child’s psychological development, leading to introversion and other personalities. 3.Advantages of inguinal hernia surgery The traditional surgical method uses a 2-5cm surgical incision in the inguinal region for treatment, and bilateral inguinal hernias take a bilateral surgical incision in the inguinal region. Compared with laparoscopic surgery, which is highly traumatic, not easy to find hidden hernia in the contralateral inguinal area and easy to have postoperative contralateral morbidity and re-operation, the intraoperative magnification effect of laparoscopic surgery can clearly distinguish blood vessels and spermatic cords, avoid side injuries, ensure the effect of high ligation of the hernia sac, the surgery is relatively simple and colleagues can explore the abdominal cavity to exclude other diseases, and the postoperative pain is small, basically painless, and about 3 days The surgery is relatively simple and can be performed by the same colleague to explore the abdominal cavity to exclude other diseases. At present, “two-hole laparoscopic high ligation of hernia sac” and “single-hole laparoscopic high ligation of hernia sac” are mostly used, which is a preferred surgical procedure for patients over 3 years old in areas where conditions are available. Patients can usually be discharged the same day or the next day, with a follow-up visit one week after surgery.
