ObjectiveTo explore the short-term and long-term efficacy of modified single-port and single-channel laparoscopic surgery for children with hydrocele of spermatic cord and testical. MethodsA total of 124 children with hydrocele of spermatic cord and testical were divided into observation group and control group using random number table, with 62 cases in each group. All patients underwent laparoscopic high ligation of vaginal process. Transumbilical and transventral puncture was performed in the control group, and modified transumbilical single-port and single-channel procedure was performed in the observation group. Before operation and after 1 day of operation, the levels of total bilirubin (TBIL), γ-glutamyl transpeptidase (γ-GGT) and serum inhibin-B (INH-B) were compared between the two groups. At 1 day and 6 months after operation, pulsatility index (PI) and resistance index (RI) of the testicular capsular artery were compared between the two groups. The operation duration, intraoperative blood loss and hospital stay were observed in both groups. The recurrence at 6 months after operation and within 3 years after operation and the complications within 6 months after operation were analyzed. ResultsIn the observation group, there were no significant changes in the TBIL and γ-GGT levels at 1 day after operation compared with before operation (P＞0.05), but the levels were significantly lower compared to the control group at the same time (P＜0.05). The INH-B levels of both groups significantly increased at 1 day after operation compared with the levels before operation, and the level in the observation group was significantly higher than that in the control group at the same time (P＜0.05). At 6 months after operation, the PI and RI of testicular capsular artery on the affected side were significantly higher in both groups compared to the indices at 1 d after operation, and the indices of the observation group were significantly higher than those of the control group at the same time (P＜0.05). There was no statistical difference in the operation duration between the two groups (P＞0.05). The intraoperative blood loss and hospital stay of the observation group were significantly less than those of the control group (P＜0.05). Within 6 months after operation, the incident rate of complications in the observation group was significantly lower than the rate in the control group (P＜0.05), but there was not significant difference in the recurrence rate between the two groups (P＞0.05). Within 3 years after operation, there was no significant difference in the recurrence rate between the two groups (P＞0.05). ConclusionModified single-port and single-channel laparoscopic surgery can obtain significant short-term and long-term efficacy for hydrocele of spermatic cord and testical in children, and is beneficial to the growth and development of children’s reproductive system.
