Paraaortic lymph node sampling has been found to be efficient in the staging of genitourinary cancers. However, the complications associated with this procedure using the traditional transperitoneal or extraperitoneal approach are considerable. Developments in endoscopic technology and instrumentation have allowed an extraperitoneal approach. Presented is a porcine model for extraperitoneal endoscopic paraaortic lymph node dissection as a staging procedure for genitourinary cancers. The pig is placed in a prone position, and an extraperitoneal pneumoperitoneum is created. Using a three-port technique, we were able to remove almost 95% of all paraaortic lymph nodes laparoscopically without any complications. The prone position allows for a fast and safe procedure because it minimizes the need for extra entry ports and gives a clear view, unobstructed by the bowel, of the back wall of the abdomen.
腹主动脉旁淋巴结采样已被证明在泌尿生殖系统癌症分期中有效。然而，采用传统经腹或腹膜外途径进行该手术相关的并发症相当多。内镜技术和器械的发展使得腹膜外途径成为可能。本文介绍了一种用于腹膜外内镜下腹主动脉旁淋巴结清扫的猪模型，作为泌尿生殖系统癌症的分期手术。将猪置于俯卧位，建立腹膜外气腹。采用三孔技术，我们能够在腹腔镜下切除几乎95%的腹主动脉旁淋巴结，且无任何并发症。俯卧位可实现快速安全的手术，因为它减少了额外穿刺孔的需求，并能提供清晰的视野，腹部后壁不受肠管阻挡。
