title: [Transumbilical single-site single-port versus single-site double-port laparoscopic varicocelectomy for varicocele in adolescents].
abstract: OBJECTIVE
  To compare the effect of transumbilical single-site single-port with that of transumbilical single-site double-port laparoscopic varicocelectomy in the treatment of varicocele in adolescents.
  
  
  METHODS
  We randomly assigned 80 varicocele patients aged 10 - 16 years to two groups of equal number to receive transumbilical single-site single-port and single-site double-port laparoscopic varicocelectomy, respectively. We compared the operation time, postoperative hospital stay, incisional pain, complications and satisfaction with the abdominal cosmetic outcomes between the two groups.
  
  
  RESULTS
  All the operations were successfully performed. The double-port group showed a significantly higher score on the Visual Analogue Scale than the single-port group (4.8 +/- 1.4 vs 3.6 +/- 1.1, t = -4.986, P < 0.01), but there were no significant differences between the two groups in the operation time ([29.8 +/- 4.2] vs [31.2 +/- 4.6] min, t = 1.383, P = 0.171), postoperative hospital stay ([1.95 +/- 0.7] vs [1.82 +/- 0.8] d, t = -0.784, P = 0.436), complications (0 vs 0) and scores on the satisfaction with abdominal cosmetic outcomes (4.6 +/- 0.6 vs 4.8 +/- 0.5, t = 1.253, P = 0.214). No recurrence, umbilical hernia, hydrocele and orchiatrophy were found in the two groups of patients at 6 months after operation, and no visible scar was observed on the abdominal surface.
  
  
  CONCLUSIONS
  With strict surgical indications, single-site single-port and single-site double-port laparoscopic varicocelectomies have similar clinical effects in the treatment of varicocele, which leave no scar on the abdominal surface. Single-site double-port laparoscopy needs no special instruments and therefore is worthier of wide clinical application.
