Abstract:
Objective To evaluate a novel lymph node (LN) sorting method on surgical resected sample guided by nanometer carbon staining and principle following the supplying artery tributory in rightsided colon carcinoma.Methods From May 2015 to June 2016,51 patients were randomly divided into two groups adopting traditional LN sorting method and that of a combination of nanometer carbon and artery guided.The final LN status were compared between the 2 groups.Results The total LN number and the positive LN in novel method group were higher than control group (437 vs.349,70 vs.54).The dissection time used,the number of harvested positive LN that was ＜ 5 mm were significantly different [(13.1 ± 3.2) minvs.(17.8 ±3.8)min,t=4.75,P=0.000;1.0±l.0vs.0.2 ±0.6,t=3.51,P=0.000].The number of patients with harvested LN less than 12,the rate of positive lymph nodes,the rate of metastasis were not significantly different (all P ＞ 0.05) between the two groups.Conclusions Use of nanometer carbon development combined with artery approach facilitates LN sorting,yielding more positive LNs,and increating the accuracy of pathological staging in right-sided colon cancer.
