[Surgical treatment of varicocele with inguinal microligation technique. 6-year experience].

Background: Varicocele is found approximately in 15% of the male population and is considered a major cause of infertility. Varicocele management include surgical (traditional or laparoscopic) or conservative techniques (sclerotherapy). The authors present their experience on microsurgical inguinal varicocelectomy. This technique has been adopted since 1992 to decrease the incidence of recidives of high spermatic vein ligation; it also permitted to use local or loco-regional anesthesia, reducing time of hospitalization and realizing a minimally invasive approach.

Methods: From 1992 to 1997, 433 microsurgical inguinal varicocelectomy with artery and lymphatic sparing have been performed at the Militar Hospital of Milan in 409 young men with idiopathic varicocele. All patients were discharged 24 hours after operation. Only those who lived particularly far from the hospital remained for 48 hours.

Results: Clinical controls were performed I, III, VI months after operation. At the third control (VI month), a new semen analysis was performed, and 65% of patients had an improvement of seminal characteristics. In 394 patients, a complete resolution of varicocele was observed; 4 patients had a recurrence of the pathology and 11 had a recidive. Seventy-three patients who presented a concomitant homolateral inguinal hernia were treated at the same time.

Conclusions: The conclusion is drawn that microsurgical ligation of spermatic veins represents a good surgical option in the treatment of varicocele. It is a quite simple technique that guarantees a low risk of recidives, permits using local or loco-regional anesthesia and can be performed in day-surgery with good results, few complications and good short and long term results.
