Laparoscopic varicocele ligation.

Varicocele, an abnormal dilatation of the pampiniform plexus, frequently contributes to male factor infertility. We performed laparoscopic varicocelectomy in 20 patients with varicoceles and abnormal seminal findings. The spermatic artery was identified and preserved in 13 patients and was clipped along with the veins in 7 patients including 1 patient with bilateral varicocele. The time required for the artery-ligating surgery ranged from 90 to 120 minutes with an average of 113.2 minutes, while the time needed for the artery-preserving technique ranged from 90 to 250 minutes with an average of 158.0 minutes. Some analgesics were administered to 11 patients, while the other 9 patients needed no analgesics. All patients were able to walk within 24 hours of the operation. The mean hospitalization period after the operation was 5.9 days. Sperm concentrations significantly improved postoperatively (p < 0.05). No difference in postoperative improvement of seminal findings was observed between artery-ligating and artery-preserving groups. A slight scrotal emphysema developed during the operation in 1 patient. Abdominal pain was experienced in 1 patient, but subsided within a few days. No serious complications were observed. The laparoscopic technique may replace routine open high ligation as the surgical treatment of choice, especially in patients with bilateral varicocele.
