Herein are reported the results obtained in 14 patients with the performance of vasovasostomy by carbon dioxide (CO2) laser. Fusion coagulation of the vas wall was successfully accomplished as demonstrated by postoperative sperm counts of over 20 million/mL in 86 per cent of the patients, and a pregnancy rate of 43 per cent in the group of patients operated on within less than ten years of original vasectomy. In contrast, those patients undergoing vasovasostomy ten years after original vasectomy had sperm counts of over 20 million/mL in 43 per cent of the cases, with a zero pregnancy rate. A significant reduction in total operative time was achieved as compared to the conventional microsurgical suture technique, corroborating the ability of the CO2 laser to simplify this technique while producing a sperm-tight anastomosis. One of the drawbacks of this operation is that it is not suited for the performance of a vasoepididymostomy which could be required in those cases in which sperm is absent from the vas fluid at the time of vasovasostomy.
本文报道了14例接受二氧化碳（CO₂）激光输精管吻合术患者的治疗结果。输精管壁的融合凝固术成功完成，86%的患者术后精子计数超过2000万/mL，在首次输精管结扎术后不到十年接受手术的患者组中，妊娠率为43%。相比之下，在首次输精管结扎术后十年接受输精管吻合术的患者中，43%的病例精子计数超过2000万/mL，但妊娠率为零。与传统的显微外科缝合技术相比，手术总时间显著缩短，这证实了CO₂激光在简化该技术的同时实现无精子渗漏吻合的能力。该手术的一个缺点是不适合进行输精管附睾吻合术，而在输精管吻合术时输精管液中无精子的情况下可能需要进行这种手术。
