Inguinal hernia is the most common condition in pediatric surgery. Because inguinal hernias in pediatric patients are caused by failure to occlude the peritoneal sphincter during embryonic testicular descent, weakness of the inguinal region is not a factor in their pathogenesis, and therefore a simple high ligation of the hernia sac is sufficient to achieve treatment without the need for additional hernia repair as in adults. For many years, the traditional open hernia bursa ligation has been the standard procedure for the treatment of pediatric hiatal hernia, but the traditional procedure requires dissection at all levels of the preperitoneum, which inevitably disrupts the anatomic structure of the inguinal canal to some extent, resulting in unnecessary injuries and complications. For example, damage to the spermatic vessels may lead to postoperative scrotal edema or testicular atrophy; damage to the vas deferens may affect future fertility; incomplete ligation may increase the chance of future recurrence; failure to explore the contralateral side may require reoperation later if the contralateral side is combined with an occult hiatal hernia. In 1982, Ger first tried laparoscopic surgery to close the inner ring opening in animal experiments, which heralded the advent of the era of minimally invasive treatment of pediatric hernia. After more than 10 years of development, it has become a more mature technique. The laparoscopic method of hiatal hernia ligation can ligate the hernia sac at a high level at the level of the internal ring opening, which is a true high ligation, and the laparoscopic magnification can clearly show the important structures around the internal ring opening to avoid injury, without dissecting the inguinal canal at all levels, with less trauma, smaller postoperative scars and faster recovery of the child. The advantages of using laparoscopy for hiatal hernia surgery have been widely recognized by scholars. At present, there are several methods of laparoscopic pediatric inguinal hernia surgery reported at home and abroad, including the 2-hole or 3-hole method with more than 2 Trocar and the modified single-hole method. Our hospital was the first in China to carry out single-port laparoscopic surgery for the treatment of hernia in children, and the original single-port laparoscopic treatment of hernia using large circular needle sutures. Since 2006, more than 3,000 cases of pediatric hiatal hernia surgery have been completed with this method, with 6 cases of postoperative complications (only 0.2%) and only 10 cases of recurrence (about 0.33%), achieving good results. This method has the advantages of more minimally invasive, no postoperative scars, short operation time (10 minutes on average), no bleeding, low postoperative recurrence rate, short hospital stay and so on. Generally, the child only needs to be hospitalized for 2 to 3 days to heal and go home (admission for examination on the first day, surgery on the second morning, and discharge on the third day), with a total hospitalization cost of about 5,000 yuan. Since its implementation, this method has not only won the praise of the parents of the children, but also the affirmation of the industry peers, and currently our department is the department that performs this procedure the most in the region. At the same time, the authors have also published the narrative of this method in the Chinese Journal of Surgery, the highest level medical journal in China, and Surgical Endoscopy, a world-renowned journal of minimally invasive surgery, which has an impact factor of 4.013.
