目的:纳米碳示踪技术在腹腔镜结肠癌根治术中的应用价值。方法:将35例结肠癌患者随机分为研究组(15例)和对照组(20例),研究组在行肿瘤组织周围黏膜或浆膜下纳米碳注射后行腹腔镜结肠癌根治术,对照组直接行腹腔镜手术,比较两组相关临床指标及淋巴结检出情况。结果:研究组与对照组的手术切口总长度、肛门排气时间、术后进食时间、住院时间差异均无统计学意义(均P>0.05),但研究组的手术时间与术中出血量明显低于对照组(均P<0.05)。两组除肠旁组淋巴结获取数目上差异无统计学意义外(P=0.078),研究组在淋巴结清扫总数目、<5mm淋巴结数目、阳性淋巴结数目方面均优于对照组(均P<0.05)。结论:腹腔镜结肠癌根治术中联合纳米碳淋巴示踪技术,能弥补腹腔镜手术触觉感的不足,做到了微创与精准并重,明显提高淋巴结检出率。
Objective: The value of nanometer carbon tracer technique in laparoscopic radical mastectomy. Methods: Thirty-five patients with colon cancer were randomly divided into study group (n = 15) and control group (n = 20). The study group underwent laparoscopic radical resection of colon cancer with or without submucosal injection of carbon nanoparticles around the tumor. Group directly laparoscopic surgery, the relative clinical indicators and lymph node detection were compared between the two groups. Results: There was no significant difference between the study group and the control group in the total length of surgical incision, anal exhaust time, postoperative eating time and hospital stay (all P> 0.05), but the operation time and intraoperative blood loss were significantly Lower than the control group (all P <0.05). There was no significant difference in the numbers of lymph nodes in the two groups (P = 0.078). The total number of lymph nodes, the number of lymph nodes <5mm, the number of positive lymph nodes in the study group were all better than those in the control group (all P <0.05) . Conclusion: The combined technique of nanocarbon lymphography and laparoscopic radical mastectomy can make up for the lack of tactile sense of laparoscopic surgery, so that both minimally invasive and precise precision can be achieved, and the detection rate of lymph node can be obviously increased.
