Laparoscopic transumbilical single-site treatment of pediatric inguinal hernia Inguinal hernia is a common pediatric condition formed due to congenital unclosed sphincter with little to no weakness of the inguinal canal wall; therefore, simple high ligation of the hernia sac can achieve the therapeutic goal. The laparoscopic extraperitoneal suture achieves both the high ligation of the hernia sac in traditional surgery and avoids the extensive dissection of the hernia sac, spermatic cord and vas deferens in traditional surgery, simplifying the operation, making it easy to operate, with less trauma, faster recovery and less pain, and also allowing exploration of the contralateral internal ring opening to detect occult hernias, avoiding the pain of postoperative recurrence on the contralateral side requiring secondary surgery, and reducing postoperative complications such as scrotal hematoma, and these advantages have been These advantages have been recognized. At present, the two-hole or three-hole method is commonly used in China, and with our modification, we have carried out single-site laparoscopic extraperitoneal suturing with a 9-gauge injection needle through the umbilical hole for the treatment of pediatric inguinal hernia, and obtained a cosmetic effect without abdominal surgical scars (see figure). Indications for surgery of pediatric inguinal hernia: (1) early surgery should be performed if there is no age limit and there is a recent history of recurrent ingrown hernia; (2) early surgery should be performed if the internal ring opening is still not closed after six months; (3) emergency surgery should be performed if the ingrown hernia fails to be repositioned by manipulation or if the time of ingrown hernia exceeds 8 hours. Every year, there are many children with testicular, ovarian and intestinal necrosis caused by incarcerated hernia, and there are even cases of bilateral testicular necrosis, which is saddening! Therefore, we advocate the concept of “treating the disease early”, and not to make the “small disease” into a “big disease”.
