Objective: 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.
