Choice of handling methods for internal ring during transumbilical single-site laparoscopic orchiopexy for cryptorchidism with bilateral processus vaginalis unclosed in children

Abstract

Objective To explore the choice of handling methods for bilateral internal ring during the transumbilical single-site laparoscopic orchiopexy for cryptorchidism with bilateral processus vaginalis unclosed in children, and evaluate the clinical effect. Methods Retrospective analysis was conducted for the clinical data of 102 children with cryptorchidism and bilateral processus vaginalis unclosed who were hospitalized at Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 2011 to January 2016.They were divided into the observation group(55 cases) and the control group(47 cases). In the observation group, the internal rings of the affected side were destroyed and stitched with a needle between the edge of arcuate of musculus trasversus abdominis and fascia trans versalis of posterior peritoneum.If the diameter of opposite internal ring was less than 0.5 cm, only a circle was destroyed.Otherwise, a circle was destroyed and sutured with a needle.In the control group, the processing methods for orchiopexy and affected side internal ring were same as the observation group.Purse string suture was done for opposite internal rings of all cases in the control group.The parameters of operative duration, intraoperative blood loss, postoperative hospital stay, postoperative complications were compared between 2 groups. Results All operations were successful in both groups, spermatic cords were reserved and testicles were in scrotum of all cases.Operative duration was significantly shorter in the observation group than that in the control group[(42.02±3.21) min vs.(48.43±4.18) min, t=-8.739, P 0.05; (2.87±0.64) d vs.(2.98±0.61) d, t=-0.853, P>0.05; 1.8%(1/55 cases) vs.2.1%(1/47 cases), χ2=0.013, P>0.05]. During a mean follow-up of 30(12-72) months, there was no case of testicular ascent or atrophy, or hernia, or hydrocele. Conclusions The transumbilical single-site 3-port laparoscopic orchiopexy for cryptorchi-dism has stable efficacy.The improved method for bilateral internal ring is simple and has satisfactory effect, which is worthy of clinical promotion.
