Abstract: Objective To investigate the value of laparoscopic high ligation of hernia sac withstraight threaded needle via single tunnel in treating pediatric inguinal hernia. Methods Set up a 3 mm supraumbilical incision and a 5 mm subumbilical incision ，place 5 mm and 3 mm Trocars were placed after the artificial pneumoperitoneum. Set up a 1 mm in surface projection of the hernia sac，then the threaded needle was pierced through this incision，and make the needle stealthed along the backside of hernia sec extraperitoneally. After crossing the spermatic vessels tip ，the hernia needle pierced peritoneum into the abdominal cavity. Pull the thread into the abdominal cavity from the needle with laparoscopic clamp till it was long enough. Pull the needle back along the tunnel slowly till it reach the original vertical extraperitoneal entrance，then let the needle stealth along the outside of hernia sec extraperitoneally and pierce into abdominal cavity at the place of previous piercing into abdominal cavity. Put the thread in abdominal cavity into the gap between the thread on needle and the hernia needle ，and pulled the thread and the needle from extraperitone gently. The thread in abdominal cavity was taken outside ， then cut and knot it. So the hernial sac were ligated twice. Results There were 218 contralateral vestigium proceseus vaginalis cases out of 427 cases，accounting for 51.2% of the patients with unilateral inguinal hernia. The average time of one side operation was about 8.5 minutes. There were 5 cases of umbilical hemorrhage，and no scrotum，groin hematoma or other complications occurred after operation. The average hospital stay was 3.1 days. 312 cases were followed up from 3 months to 24 months after operation. No recurrence or surgical knots reaction were found. Conclusion Laparoscopic high ligation of hernia sac with straight threaded needle via single tunnel is satisfactory and worthy of promotion.
