Abstract

Objective: The aim of this study was to explore the true efficacy and potential advantages of lymphatic sparing laparoscopic varicocelectomy (LSV) over lymphatic non-sparing laparoscopic varicocelectomy (LNSV) in children and adolescents.

Methods: A search was made for studies published up until 31 August 2010 using the terms “lymphatic sparing varicocelectomy”, “laparoscopy”, “adolescent” and “children” in the Medline, Embase, Ovid, Web of Science, and Cochrane databases. Randomized controlled trials (RCTs) and observational clinical studies (OCSs) comparing LSV and LNSV were included. A systematic review and meta-analysis was performed using odds ratios (ORs) for dichotomous variables.

Results: Out of 127 studies, 2 RCTs and 4 OCSs were eligible for inclusion, comprising 489 cases of LSV and 307 cases of LNSV. The hydrocele rates after LSV were significantly lower than after LNSV (OR=0.19; 95% confidence interval [CI]=0.10 to 0.36; p<0.00001). However, no significant difference was observed between LSV and LNSV with regard to recurrence (OR=0.65; 95% CI=0.32–1.33; p=0.24) or catch-up growth (OR=2.14; 95% CI=0.97–4.72; p=0.06).

Conclusion: LSV is valuable in reducing the incidence of postoperative hydrocele, with similar recurrence and catch-up growth rates as LNSV. A series of RCTs are warranted to explore the efficacy of LSV in the management of varicocele in children and adolescents.
