BACKGROUND/AIM: According to limited current reports, therapeutic paraaortic lymph node (PALN) dissection with intensive combined therapy for colorectal cancer improves prognosis in select patients. Laparoscopic PALN dissection is a difficult technique that has not yet been established. We applied this procedure using an intraoperative fluorescence navigation technique with a near-infrared ray catheter (NIRC™) fluorescent ureteral catheter (NIRFUC).
We evaluated the utility of laparoscopic fluorescence navigation and the short-term outcomes of 6 patients undergoing laparoscopic PALN dissection.
There were 3 surgeries for synchronous metastasis and 3 surgeries for recurrent metastasis. The mean surgical duration, blood loss, and postoperative hospital stay were 677 (range=518-1,090) min, 7.5 (range=3-1,600) ml, and 14 (range=9-33) days, respectively. Postoperative complications (Clavien-Dindo grade >III) occurred in 1 case.
Dissection around the ureter was navigated with a NIRFUC. Fluorescence ureteral navigation facilitated completion of the complex laparoscopic PALN dissection procedure.
背景/目的：根据目前有限的报道，对结直肠癌采用强化联合治疗并进行治疗性腹主动脉旁淋巴结（PALN）清扫可改善部分患者的预后。腹腔镜PALN清扫是一项尚未成熟的困难技术。我们应用术中荧光导航技术及近红外线导管（NIRC™）荧光输尿管导管（NIRFUC）实施了该手术。
我们评估了腹腔镜荧光导航的实用性以及6例行腹腔镜PALN清扫患者的短期结局。
3例为同步转移手术，3例为复发转移手术。平均手术时间、失血量及术后住院时间分别为677（范围=518 - 1090）分钟、7.5（范围=3 - 1600）毫升和14（范围=9 - 33）天。术后并发症（Clavien-Dindo分级>Ⅲ级）发生1例。
使用NIRFUC对输尿管周围进行清扫。荧光输尿管导航有助于完成复杂的腹腔镜PALN清扫手术。
