Abstract: Objective：To assess the effect of different alimentary reconstruction on glucose in gastric cancer patients complicated with type 2 diabetes. Methods：Retrograde analyzing 55 cases of gastric cancer with type 2 diabetes from 2004 to 2008.These patients were divided into three groups: distal gastrectomy with BillrothⅡanastomosis(n=25),total gastrectomy with esophago-jejunum Roux-en-Y anastomosis(n=19), distal gastrectomy with BillrothⅠanastomosis(n=11). Results：Comparing to the third group,the blood glucose level of the former two groups after surgery showed a steady and sustained descent(P< 0.05).The effective rate was 72.00% and 73.68% respectively.However, there was no difference in the control of diabetes between the former two groups(P>0.05). Conclusions：BillrothⅡanastomosis or Roux-en-Y anastomosis is an effective method for the patients of gastric cancer with type 2 diabetes.
