Comparison of transumbilical single-site laparoscopy and traditional laparoscopy for children with high-level intra-abdominal testes

Purpose: Laparoscopy is the most frequently performed surgery in children with high-level intra-abdominal testes. The aim of the study was to compare outcomes of transumbilical single-site laparoscopy and traditional laparoscopy in children with high-level intra-abdominal testes at Hainan Women and Children's Medical Center. Methods:Retrospective review of children with high-level intra-abdominal testes undergoing transumbilical single-site laparoscopy between March 2019 and March 2022 was performed.The patients were divided into transumbilical single-site laparoscopy and traditional laparoscopy groups. The age, clinical characteristics of high-level intra-abdominal testes, and internal ring were evaluated. The results were assessed for complications, operative time, tension of spermatic cord, location of the testis being fixed, hospital stay, and satisfaction Results: Seventy-two children were included in the analysis, thirty-eight patients in traditional laparoscopy, thirty-four patients in intransumbilical single-site laparoscopy. The median duration of surgery was 89.29 mintues in intransumbilical single-site laparoscopy versus 91.26 mintues in traditional laparoscopy (p=0.699) .The median age in intransumbilical single-site laparoscopy was 21.00 months, traditional laparoscopy was 20.53 months.There was no signifcant difference in spermatic cord location of the testis being fixed,and hospital stay in both groups, and no postoperative complications were reported in both groups. However, parents of intransumbilical single-site laparoscopy have higher satisfaction than traditional group(p=0.048). Conclusion:The transumbilical single-site laparoscopy for children with high-level intra-abdominal testes was safely adopted at our institution, should be considered as the preferred surgical approach.
