Inguinal hernia is a common surgical condition in children and is not difficult to diagnose based on the history and physical examination provided by the parents. What is the appropriate age for surgery? Different hospitals and doctors give different answers, so how should parents choose? Based on the current principles of diagnosis and treatment in our general surgery department and the authoritative original textbook (the attached figure is from the original Pediatric Surgery published in 2013), we would like to make a discussion here for the reference of parents. Previously, it was theoretically believed that self-healing was possible in children younger than 6 months; for children with inguinal hernia older than 6 months, self-healing was less likely. Therefore, children with inguinal hernias older than 6 months of age require surgical treatment. Medications, injections, and “hernia belts” have no reliable clinical evidence of their therapeutic effectiveness and are therefore not recommended as a radical treatment. As for children younger than 6 months, most doctors in China, still take a relatively conservative approach to postpone the age of surgery, but we often encounter in our clinical work complications that occur during this waiting process (hiatal hernia impaction requiring emergency surgery, even with intestinal necrosis). Therefore, in order to prevent the occurrence of intussusception, we recommend early surgery of inguinal hernia once diagnosed, especially in children with frequent “blocks” or even multiple intussusceptions, regardless of age. At present, the main surgical procedure is the high ligation of the hernia sac, but minimally invasive surgery is also available, with short hospitalization time, precise efficacy and high patient satisfaction.
