AbstractObjective: To evaluate safety and efficacy of a novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy for children. Methods: A retrospective study was carried out comparing the novel ligation and conventional ligation performed by a single surgeon between July, 2017-July, 2018. The patients were divided into the novel group (42 cases) and the conventional group (59 cases). In the novel group, transumbilical single-site multiport laparoscopic orchiopexy was performed and the bilateral internal rings was stitched with "8" pattern suture. In the conventional group, the conventional TriPort laparoscopic orchiopexy was performed and purse string suture was used to fix the internal rings. The parameters of operative duration time, postoperative hospital stay; postoperative complications were compared between 2 groups. Results: All operations were successful. No Perioperative period complications were found and all patients were discharged within 4-6 days after operation. There is no statistic difference in the surgery time and hospitalization day. However, there is significant difference in the Pain face scale scores after day 2(1.60±0.73 VS 2.02±0.86). And there is no scar and the satisfactory cosmetic could be seen in scrotum and inguinal area in the novel group. Conclusion: The novel ligation was safety and efficacy. It is relatively easy to perform with smaller scar and less pain. We propose the novel ligation as a more viable treatment option for pediatric cryptorchidism with bilateral patent processus vaginalis.© The author(s).
