This report describes a technique for standing laparoscopic vasectomy in stallions through a prospective descriptive study. A preliminary study was carried out with two experimental intact male horses and subsequently the procedure was performed in two clinical cases. These horse owners want to keep their animals in the most possible natural way, preserving its stallion behaviour in a herd without generating offspring. The horses were sedated and restrained in stocks and laparoscopic vasectomy was performed using three portal sites in both paralumbar fossae recording surgical times. A 4-cm segment of each ductus deferens (DD) was occluded with laparoscopic vessel sealing devices and subsequently excised. Semen collection was performed using an artificial vagina before the laparoscopic procedure and at 15 and 60 days postoperatively. Sexual behaviour and spermiogram were analysed. Two months after vasectomy, control laparoscopy was performed in experimental horses to assess the surgical site. Bilateral vasectomy could be performed without intraoperative complications in a mean surgical time of 20 min per DD. Success of the procedure was confirmed in all cases by azoospermic ejaculates 60 days after vasectomy. This is the first time that the technique for laparoscopic vasectomy is described in horses.
本报告通过前瞻性描述性研究描述了一种在种马中进行腹腔镜输精管切除术的技术。初步研究在两只实验性完整雄性马中进行，随后在两个临床病例中进行了该程序。这些马主希望以最自然的方式饲养动物，保持其在马群中的种马行为，而不产生后代。马被镇静并约束在畜栏中，在两个腰旁窝中使用三个端口进行腹腔镜输精管切除术，并记录手术时间。用腹腔镜血管密封装置闭塞每个输精管（DD）的 4 厘米段，然后切除。在腹腔镜手术前和术后 15 和 60 天使用人工阴道进行精液采集。分析性行为和精子分析。在实验马中，在输精管切除术 2 个月后进行了对照腹腔镜检查，以评估手术部位。双侧输精管切除术可以在每侧 DD 的平均手术时间 20 分钟内无术中并发症进行。在输精管切除术后 60 天，所有病例的无精子精液均证实手术成功。这是首次在马中描述腹腔镜输精管切除术的技术。
