Abstract:Objective To explore the clinical efficacy of the new transumbilical laparoscopy and the conventional three-port method in the treatment of unilateral huge ( ≥ 15 mm) indirect inguinal hernia.Methods A retrospective analysis was conducted on the clinical data of 213 children with unilateral huge ( ≥ 15 mm) indirect inguinal hernia admitted to the hospital from July 2020 to August 2023. According to different surgical methods, the children were divided into the three-port group (107 cases, undergoing three-port laparoscopic high ligation of hernia sacs) and the new group (106 cases, undergoing new transumbilical laparoscopic surgery). The surgical indicators of the two groups of children, the face, legs, activity, cry, consolability (FLACC) score, parents’ satisfaction with the appearance of the incision, testicular volume, postoperative complications and recurrence rate (within 1 year after surgery) were compared.Results The intraoperative blood loss and the number of incisions in the new group were less than those in the three-port group, while the incision length, operation time, postoperative incision healing time and hospital stay were shorter than those in the three-port group. The differences were statistically significant (P < 0.05). At 6, 12, 24 and 48 hours after the operation, the FLACC score of the new group was lower than that of the three-port group, and the difference was statistically significant (P < 0.05). The satisfaction rate of parents of children in the new group with the appearance of the incision was 100.00%, which was higher than 88.79% in the three-port group, and the difference was statistically significant (P < 0.05). The volume of the affected testicle in both groups before the operation was smaller than that of the healthy side, and the volume of the affected testicle one year after the operation was larger than that before the operation. The differences were statistically significant (P < 0.05). One year after the operation in the new group, there was no statistically significant difference in the testicular volume between the healthy side and the affected side (P > 0.05). There was no statistically significant difference in the total incidence of complications and overall recurrence rate between the two groups (P > 0.05).Conclusion Compared with the conventional three-port method, the new transumbilical laparoscopic surgery has the characteristics of convenient operation, less trauma, less pain, faster postoperative recovery and a beautiful incision. It has more advantages when applied in the treatment of unilateral huge indirect inguinal hernia≥15 mm.
