To explore the technical advantages on sorting the lymph node by nanometer carbon development joint in artery approach in descending colon carcinoma.

From June 2015 to December 2016, the 60 patients with descending colon cancer in General Surgery Department of Henan Provincial Tumor Hospital were randomly divided into two groups, namely the traditional method and the new method. The average detection number of the lymph node, the inspection time, total number of lymph node, the number of the diameter less than 5 mm, the total and positive number of the different station were compared.

The total number of lymph node and the positive ones in observation group were more than control group (554: 427 vs 95: 59). The average detection number (21.50±6.03 vs 13.61±1.97, t=25.970, P<0.001), inspection time (12.31±2.5 vs 17.4±3.2, t=13.491, P<0.001), number of the diameter were less than 5mm (4.98±1.76 vs 2.86±1.21, t=8.279, P<0.001). The number of detection were less than 12 (Χ²=4.773, P=0.029). The total and positive lymph node number of first and second station were significantly different (11.32±4.41 vs 5.71±1.91, t=15.128, P<0.001)、(7.49±1.78 vs 5.58±1.68, t=10.358, P=0.001)、(5.11±3.48 vs 2.19±0.83, t=4.300, P<0.001)、(3.69±2.32 vs 1.91±0.61, t=3.501, P=0.001). The number of third station (4.21±1.43 vs 4.06±1.64, t=0.714, P=0.476) and positive number of third station (2.50±1.60 vs 1.60±0.52, t=1.680, P=0.112) were no significantly differences.

Using the nanometer carbon development joint in artery approach method provided an easier operation and enhanced the number of inspection lymph nodes and the accuracy of pathological staging in descending colon colon carcinoma.
