Abstract: Objective  To explore the feasibility,safety and efficacy of laparoscopy combined with medial umbilical fold repair for the treatment of giant inguinal hernia in children.
Methods  We retrospectively analyzed the clinical data from 97 cases of high ligation of simple hernia sac under laparoscopy and 79 cases laparoscopy combined with medial umbilical fold repair.Clinical data were compared between the two groups.
Results  The operation time of the combined group was(26.14±2.84),and the operation time of the simple group was(22.21±3.00) min.There was a statistical difference between the two groups(P<0.05).There was no significant difference in perioperative inflammatory indexes between the two groups.after early complications including wound infection,knot reaction,scrotal edema,effusions scrotal no significant difference(P>0.05),6 cases of recurrence in the simple group and no recurrence in the combined group.The recurrence rate of the two groups was There was a statistical difference(P<0.05).There was no significant difference in blood flow of spermatic cord(P<0.05) no significant difference in blood flow of spermatic cord(P>0.05),and no testicular atrophy occurred.
Conclusion  Inguinal hernia in children with laparoscopy combined with medial umbilical fold repair can reduce recurrence,without additional inflammatory reaction and other surgical stress incidence of postoperative complications.
