Application of a new-type wire clamp in laparoscopic operation of indirect hernia in children

Objective  To explore the application value of a new-type wire clamp in laparoscopic high ligation of indirect inguinal hernia sac in children.

Methods  The clinical data and follow-up data of 112 children with laparoscopic high ligation of indirect inguinal hernia sac were analyzed retrospectively. According to the wishes of the children's guardians, 54 cases with laparoscopic high ligation of hernia sac by a new-type wire clamp were selected as laparoscopic group, and 58 cases with small incision high ligation of indirect inguinal hernia sac were selected as control group. The operation time, intraoperative blood loss, total incision length, time to postoperative bed-off activity and postoperative hospital stay were compared between the two groups. After 4 to 16 months of postoperative follow-up, the incidence of postoperative complications and the incidence of contralateral metachronous hernia (MCH) were compared between the two groups.

Results  All the operations were successfully completed in children. In the laparoscopic group, 16 children with contralateral concealed indirect hernia were detected during operation and were treated at the same time. The intraoperative blood loss, the total length of incision, the time to postoperative bed-off activity and the length of hospital stay in the laparoscopic group were significantly lower than those in the control group, and the incidence of complications during follow-up was significantly lower than that in the control group (P < 0.05). Among the children with unilateral surgery, there was no case with MCH in the laparoscopic group, which was significantly less than 11 cases with MCH in the control group (P < 0.05).

Conclusion  The new-type wire clamp in laparoscopic high ligation of indirect hernia sac in children has the advantages of high safety, small side injury, low cost and convenient operation.
