ABSTRACT

Objective To evaluate the clinical application value of local injections of carbon nanoparticle in gastrectomy of stomach neoplasms.Methods Forty cases of stomach neoplasms with local injections of carbon nanoparticle in gastrectomy of stomach neoplasms were as experimental group,and 40 cases of stomach neoplasms with conventional gastrectomy of stomach neoplasms were as control group.The number of removed tiny lymph node and transferred tiny lymph node was compared.Results There was significant difference in the average number of removed tiny lymph node N1,N2,N3 between experimental group and control group (5.120 ± 0.455 vs.2.900 ± 0.245,3.890 ± 0.367 vs.1.750 ± 0.256,1.790 ± 0.224 vs.0.590 ± 0.054)(P ＜ 0.01).There was significant difference in the average number of transferred tiny lymph node N1,N2,N3 between experimental group and control group (1.090 ±0.087 vs.0.430 ± 0.044,0.550 ± 0.052 vs.0.340 ± 0.027,0.410 ± 0.044 vs.0.130 ± 0.013)(P ＜ 0.05).There was no significant difference in postoperative complications,mortality and length of hospital stay(P＞ 0.05).Conclusion Carbon nanoparticle in gastrectomy of stomach neoplasms is a simple,safe,easy method,and it has certain supplementary role in conventional gastrectomy of stomach neoplasms.
