Abstract:
Objective To explore the relationship between peritoneal lavage cytology in gastric carcinoma and lymph node metastasis.Methods From June 2012 to May 2014,intraoperative peritoneal lavage for cancer cells was carried out in 226 gastric cancer patients undergoing gastrectomy.During the process 63 patients were irrigated with 500 ml of normal saline,while the others were using 1 000 ml.D2+ lymph nodes dissection was performed to evaluate the relationship between peritoneal lavage cytology in gastric carcinoma and lymph nodes metastasis.Results The positive rates of exfoliative carcinoma cells were 11.1％ in the 500 ml group and 9.2％ in the 1 000 ml group (x2 =0.188,P=0.695).In both groups,rate of exforliative cancer cells were positively related to lymph node metastasis,the numbers of positive lymph nodes,the station of lymph nodes metastasis,the rate of the lymph nodes metastasis and that of the second station (all P ＜ 0.05),but not to the numbers of the lymph node cleaned (P ＞ 0.05).Conclusions Lymph nodes metastasis was an important risk factor that contribute to exfoliated carcinoma cells in patients with gastric carcinoma,and especially in those with lymph nodes metastasis at the second station.
