title: [The advantage of artery approach in lymph node sorting of rectal cancer].
abstract: Objective:To explore the technical advantages of artery approach in lymph node sortingofrectal cancer.Methods:Sixty patients with rectal cancer who treated in general surgery department of Henan provincial tumor hospitalfrom July 2015 to January 2016 were enrolled. Patientswere divided into two groupsrandomly.Lymph node sorting methods of control group andobservation group were the traditional method and the artery approach method respectively. The total number of lymph nodes, the average inspection number, the patients number of lymph nodes less than 12, the number of positive lymph nodes, the metastasis rate of the patients, the number of average diameter less than 5 mm, the number of the positive lymph nodes which average diameter less than 5 mm, the sorting time of lymph nodes, the total number of every stationand other indicators were collected and compared.Results:There wasa significant difference between the observation group and the control groupin the total number(553 vs 395,P<0.05), the number of positive ones(96 vs 54,P<0.05), average inspection number(18.43±5.93 vs 13.27±1.96,P=0.000), the sorting time (min) (14.1±2.5 vs 17.4±3.2,P=0.000), the average diameter less than 5 mm number(4.73±1.31 vs 1.23±1.14,P=0.000), the number of positive ones average diameter less than 5 mm(0.97±1.03 vs 0.20±0.55,P=0.010), the first(8.17±4.58 vs 5.07±1.96,P=0.000) and second station(6.57±1.87 vs 4.90±1.69,P=0.001)inspection number.The inspection number less than 12, the positive rate of lymph node, the metastatic rate of the patient and the inspection number of third station have no significant differences (allP≥0.05).Conclusion:Theartery approach method inrectal cancer lymph node inspectionhas many advantages such as simple operation, obtaining more lymph nodes and more accurate pathological staging.
