RESUMO
OBJECTIVE: To study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele. METHODS: This study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters. RESULTS: All the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair. CONCLUSION: SAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.
