To analyze the effect of radical gastrectomy on the survival rate of patients with no invasion of anterior lobe of transverse mesocolon or pancreatic capsule.

From August 2010 to August 2012, one hundred and thirty-three patients with gastric cancer who underwent radical gastrectomy in Xi’an Fengcheng Hospital were divided into the observation group (66 cases) and the control group (67 cases), according to the random number table. In the observation group, the anterior transverse transectional mesial membrane and the pancreas capsule were removed during the operation. The control group retained the anterior lobe of transverse mesocolon and pancreatic capsule. The clinical data and operation conditions between the two groups were compared. Survival rate was calculated by Kaplan-Meier method. Univariate analysis was used to fine out the factors influencing postoperative cancer metastasis in the observation group.

The operation time, number of lymph node dissection in the observation group were significantly more than those in the control group (t=3.613, 4.222, both P<0.01). Pathological examination in the observation group showed that 5 cases (7.58%) had cancer metastasis and metastasis rates were significantly different in clinical stage, depth of invasion, lymph node metastasis and tumor location (all P<0.05). Logistic regression analysis showed that the clinical stage, depth of invasion and lymph node transfer range were independent risk factors for cancer metastasis. There were no significant differences between the two groups in the mean survival time and the 1-, 3-, 5-year survival rate (t=1.240, χ²=0.086, 0.038, 0.513, all P>0.05).

For patients with high degree of lymph node metastasis, late clinical stage and high degree of tumor infiltration are more likely to have metastasis to the anterior mesangial membrane and pancreas. The radical resection of the anterior gingival membrane and pancreas in radical surgery has no significant effect on the survival rates.
