“The incidence of inguinal hernia is one of the most common diseases in pediatric surgery, with a prevalence of about 1-4% and higher in premature infants; it is rare in females, and the incidence is about one-tenth of that in males. Inguinal hernia presents as an abnormal mass in the inguinal region, partially extending into the scrotum, and may be associated with pain, vomiting, and serious complications such as intestinal perforation, testicular ischemic necrosis, and ovarian torsion/ischemic necrosis if embedded for too long. Therefore, untreated inguinal hernia, which is usually considered as a “minor problem”, can become a “major problem”. Although minimally invasive inguinal hernia surgery has become largely popular, there are still problems such as recurrence, abdominal wall scars, and postoperative pain in the inguinal region in various ways. The minimally invasive hernia surgery with a single needle puncture recently reported by Associate Professor Shuai Li of the Department of Pediatric Surgery of the Union Hospital has been recognized by both the most prestigious international journal in the field of hernia, Hernia, and the most prestigious journal in the field of pediatric surgery, Journal of Pediatric Surgery (corresponding author Professor Shaotao Tang and first author Associate Professor Shuai Li). This procedure can be done with a common hernia needle (cost saving), and the high ligation of the hernia sac is accomplished by a single abdominal wall puncture, which not only avoids the discomfort in the inguinal region (90% reduction in incidence) caused by the reaction to the thread knot of the traditional hernia needle procedure (two abdominal wall punctures), but also is easier than the classic laparoscopic hernia suture procedure (50% reduction in operative time) and has the potential to reduce the recurrence rate of hernia (less than 0.1%). At the same time, this surgical improvement greatly reduces post-operative pain and speeds up post-operative recovery, with the ability to eat after awakening from anesthesia and to resume free movement and discharge within 24 hours after surgery, truly achieving the ideal requirements of minimally invasive, comfortable, and scar-free appearance.
