Abstract: Objective : To analyze the related factors of lymphatic fistulas (LF) of postoperative patients with gastric carcinoma. Methods : The relationship of LF and tumour stage and tumour site and surgical style and lymphatic metastasis and early enteral nutrition and cirrhosis of liver was analyzed retrospectively. Results : The mean incidence rate of postoperative LF is 7.6% . The rate of early enteral nutrition group is higher than that of non-enteral nutrition group (14.29% vs 3.70, P< 0.01).The rate of pTNM II and III stage group is higher than that of pTNM I and IV stage group, and the rate of pTNM III group is higher than that of pTNM II group (11.95% vs 7.94%,P<0.05). The rate of surgical group beyond D₂ style is higher than that of surgical group with D₂ style (11.05% vs 4.23%,P<0.01). The rate of group of middle-superior carcinoma of stomach is higher than that oi inferior group(11.80% vs 3.05%,P<0.01). The rate of group with lymphatic metastasis is higher than that of group with non-lymphatic metastasis (9.59% vs 4.07% , P <0.05). However, the difference between the group with cirrhosis of liver and that with non -cirrhosis of liver is no statistical significance (8.09% vs 6.54%). Conclusion : Risk factors of LF of postoperative patients with gastric carcinoma include surgical style D₂ or beyond D₂, pTNM III stage, middle-superior carcinoma of stomach, lymphatic metastasis and postoperative early enteral nutrition.
