目的评价以纳米碳作为手术时淋巴示踪剂在腹腔镜结直肠癌根治术中的应用效果。方法回顾性分析行腹腔镜手术的60例结直肠癌患者的临床资料,根据术前是否应用纳米碳淋巴示踪剂标记分为两组:试验组32例,术前应用纳米碳淋巴示踪剂标记;对照组28例未用。比较两组手术安全性、淋巴结检出情况及并发症发生率。结果两组手术时间、术中出血量、术后肛门排气时间、术后并发症发生率差异均无统计学意义(P>0.05)。试验组淋巴结检出数、微小淋巴结(<5cm)检出数均多于对照组(P<0.05)。结论在腹腔镜结直肠癌根治术中应用纳米碳淋巴示踪剂安全、可行,有助于提高淋巴结检出率。
Objective To evaluate the effect of nano-carbon as a lymphatic tracer in laparoscopic radical resection of colorectal cancer. Methods The clinical data of 60 patients with colorectal cancer who underwent laparoscopic surgery were retrospectively analyzed. According to the preoperative application of Nano-carbon lymphatic tracer, they were divided into two groups: experimental group (n = 32), preoperative application of carbon nano-tracer Marked; control group 28 cases not used. The safety of surgery, the detection of lymph nodes and the incidence of complications were compared between the two groups. Results The operation time, intraoperative blood loss, postoperative anal exhaust time, postoperative complication rate had no significant difference (P> 0.05). The number of detected lymph nodes and the number of small lymph nodes (<5cm) in the experimental group were more than those in the control group (P <0.05). Conclusion The application of nanocarbon lymphatic tracer in laparoscopic radical resection of colorectal cancer is safe and feasible, which is helpful to improve the detection rate of lymph nodes.
