Laparoscopic vs open varicocelectomy in children and adolescents: review of the recent literature and meta-analysis.

PURPOSE Laparoscopic varicocelectomy has gained popularity in recent years. The aim of this study was to identify clinical evidence about the reliability of this technique in the recent literature. METHODS We performed a Medline search for articles published during the last 10 years, using the key words "varicocele," "treatment," and "adolescent." As limits, we used last 10 years, adolescent, clinical trials, randomized controlled trials, meta-analysis, and multicenter retrospective and prospective studies. The results were investigated in recurrence and hydrocele formation. RESULTS We pooled 37 studies, but 26 of these were excluded because they were neither relevant nor concerned an adolescent population. Meta-analysis showed that there was no statistical difference between laparoscopic surgery and open surgery in recurrence rate and postoperative hydrocele rate. In the laparoscopic group, the incidence of recurrence was higher in the patients undergoing artery ligation compared to patients undergoing artery and venous ligation. Furthermore, a lower rate of postoperative hydrocele was recorded in patients undergoing dye injections before laparoscopic ligation. CONCLUSIONS Meta-analysis and literature analysis showed that the results after laparoscopic varicocelectomy are comparable to other surgical procedures. The laparoscopic approach has the advantage to treat simultaneously bilateral varicocele.
