To investigate the complications and its prevention of laparoscopic surgery in the treatment of inguinal hernia in children.

From January 2015 to January 2019, 1040 children with inguinal hernia were admitted to Xiaogan Hospital, which is affiliated with Wuhan University of Science and Technology. All children underwent laparoscopic high ligation of the hernia sac under general anesthesia with a hernia hook needle. Postoperative outpatient and telephone follow-up of the children were followed up for postoperative complications, and the prevention and treatment strategies were summarized and analyzed.

Laparoscopic surgery was successfully completed in all children. Among the complications, 23 cases were indurated under the skin of the inguinal region; 5 cases were complicated with hydrocele after operation, 3 cases were absorbed after pumping the liquid, 2 cases were operated again after ineffective pumping; 3 cases had recurrence and reoperation again; 3 cases were treated with line head reaction, 2 cases recovered after line head excretion, 1 case was reoperation again; 2 cases were treated with umbilical hemorrhage, 1 case was relieved after compression, 1 case was sutured with incision suture to stop bleeding; 2 cases were treated with prolapse of omentum in the umbilical, and 2 cases were sutured with removal of omentum. Surgical complications mostly occur in early-stage cases, and later complications can be reduced by improving surgical methods and details.

Subcutaneous induration, postoperative hydrocele, and umbilical puncture are more common postoperative complications of laparoscopic treatment of inguinal hernia in children, which can be avoided by improving surgical methods and details.
