Laparoscopic lymphatic sparing varicocelectomy in adolescents.
OBJECTIVE
Laparoscopic varicocelectomy is similar to an open Palomo repair. Both procedures involve en masse ligation of the internal spermatic cord, and both are associated with a 1% to 3% incidence of recurrence and up to a 30% incidence of hydroceles. We sought to determine the impact of lymphatic preservation on hydrocele formation and the success of varicocelectomy.


METHODS
We retrospectively evaluated 191 patients with a mean age of 15.2 years who underwent laparoscopic varicocelectomy and at least 6 months of followup. Patients were divided into 2 groups-those who had undergone a lymphatic sparing procedure and those who had undergone a nonlymphatic sparing technique. The incidence of recurrence/persistence, postoperative hydrocele formation and postoperative hydrocele requiring surgery or aspiration was analyzed.


RESULTS
A total of 174 laparoscopic lymphatic sparing procedures (132 patients, 42 bilateral) and 88 nonlymphatic sparing repairs (59 patients, 29 bilateral) were performed, with a mean followup of 26.1 months. Lymphatic sparing surgery was associated with a decreased incidence of postoperative hydrocele (3.4% vs 11.4%, p = 0.025). There was no significant difference in incidence of persistent or recurrent varicocele requiring reoperation following lymphatic sparing (5 sides, 2.9%) vs nonlymphatic sparing (4 sides, 4.5%) varicocelectomy (p = 0.736).


CONCLUSIONS
Laparoscopic lymphatic sparing varicocelectomy is preferable to an open or laparoscopic Palomo repair that does not preserve the lymphatics. It has a significantly lower incidence of postoperative hydroceles, especially those requiring surgical intervention, and still maintains a low incidence of persistence/recurrence. The procedure is especially advantageous for bilateral varicocelectomy.
