ABSTRACT
Objective To evaluate the clinical effect of treatment for high intra-abdominal cryptorchidism of children with transumbilical single-site and multichannel laparoscopic single stage Fowler-Stephens (F-S) orchiopexy.Methods The case records of the intra-abdominal cryptorchidism of children who had undergone transumbilical single-site laparoscopic single stage F-S orchiopexy were reviewed retrospectively in Children's Hospital Affiliated to Capital Institute of Pediatrics between January 2011 and January 2017,were assigned as the observation group,whose age ranged from 1 to 8 years and average age was 18 months,with 22 unilateral and 8 bilateral,38 testis in total.A total of 31 children with intra-abdominal cryptorchidism who had undergone laparoscopic two stage F-S orchiopexy were assigned as the control group,whose age was from 11 months to 9 years and average age was 20 months,with 23 unilateral and 8 bilateral,39 testis in total.Postoperative follow-ups were conducted with the evaluation index included the testical position,with or without atrophy.The procedure effect and postoperative complications were observed,and the difference between two operation methods was evaluated.Results Operations in all cases were successful in both groups without intraoperative complication.A total of 38 testis were operated with single stage F-S orchiopexy in the observation group,and 39 testis were operated with two stage F-S orchiopexy in the control group.Postoperative complications included scrotum wound infection one case and scrotum hematoma in one case in the observation group,and abdominal wall emphysema in one case,intestinal obstruction in one case as well as umbilicus infection 1 case in control group.Follow-ups ranged from 6 months to 6 years,median 24 months.All testicals were within the scrotum,and each group had 1 case of testical atrophy.The difference of postoperative complication and effect between two groups had no statistical significance(x2 =0.184,0.107,all P ＞ 0.05).Conclusions Outcomes between single stage and two stage F-S orchiopexy are similar.The transumbilical single-site laparoscopic F-S orchiopexy not only has the satisfactory effect,but also saves some patients from reoperation and secondary anaesthesia,but doctors must be aware of the indications and contraindications of this procedure should be brought to attention.
