Abstract：Objective To investigate the application value of nanocarbon lymphatic tracer in the treatment of gastric cancer by preoperative endoscopic injection .Methods From May 2013 to April 2015, 86 patients underwent D2 radical were enrolled, according to the different timing of injection of nanocarbon lymph tracer , they were divided into the preoperative group (40 cases) and operation group (46 cases), preoperative group at preoperative 24 h were injected nanocarbon suspen-sion 1 ml through endoscopic gastric mucosal , operation group during operation performed the gastric subserosal injection of nanocarbon mixed suspension 1 ml, compared the lymph examination and lymph black staining between the 2 groups.Results The preoperative group ’ s average detection of lymph node number , D2 lymph node detection number and diameter equal or less than 5 mm’s lymph nodes detection were significantly higher than that of the operation group ( P <0.05), the mean lymph node detection time was significantly shorter in the operation group ( P <0.05) and D2 lymph nodes black staining number was significantly higher than that in the operation group ( P <0.05), and D1 lymph node average detection and black straining revealed no significant differences ( P >0.05).Conclusion Preoperative endoscopic injection of nanocarbon lymph tracer can contribute to the lymph node staining and improve the detection of lymph node ;shorten the lymph node dissection time, and help to detect of the smaller lymph node .
