A. The best method recognized worldwide for treating pediatric hernia is hernia sac high ligation, that is, the hernia sac (i.e. peritoneum) is ligated and closed at the mouth of the hernia ring with silk thread, and the higher the position of the ligature and the closer to the hernia ring, the better the effect. Traditional surgery by Sanxiong Huang of the First Hospital of Huzhou Normal College of Abdominal Minimally Invasive Surgery: A small incision of 2-5 cm is made in the skin of the lower abdomen of the child, the subcutaneous fat and the tendon membrane of the external oblique abdominal muscle are incised layer by layer, the spermatic cord tissue is separated, and the hernia sac is isolated and then ligated at a high position. Laparoscopic surgery: 2-3 small puncture holes are made in the umbilicus and lower abdomen (our hospital has special laparoscopic instruments for pediatric patients) to enter the abdominal cavity from the inside out, and this advantageous surgical pathway, the ligature is definitely in the highest position, so satisfactory results are desirable; second, the vas deferens and vascular structures in the inner orifice of the hernia sac are clearly revealed under the magnified view of laparoscopy, which avoids the dissection of the spermatic cord tissue in the inguinal region of traditional surgery Therefore, the potential risk of intraoperative damage to the spermatic cord, blood vessels and other side injuries is greatly reduced; third, laparoscopy can simultaneously explore both inguinal regions in one operation without increasing the wound (traditional surgery can only see both sides from the physical appearance, and incisions must be made on both sides, and there may be omissions), and both unilateral and bilateral operations only require three 0.35, 0.5 and 1.0 cm incisions on the abdominal wall. The scars are very small after surgery, which is a real minimally invasive surgery. Fourth, the trauma is small, and the children basically have no obvious pain after the operation, and the recovery is fast, and they can resume eating and drinking within 6 hours, and most of them can walk out of the hospital the day after the operation. The probability of postoperative complications, such as wound infection and scrotal swelling after laparoscopy, is significantly lower than that of traditional surgery.
