【摘要】 目的 觀察糖尿病合并胃癌圍手術期患者應用胰島素泵的治療效果。 方法 2004年1月-2010年12月收治的胃癌合并2型糖尿病患者86例，將患者隨機分為常規組（A組）46例和胰島素泵組（B組）40例，比較兩組患者在血糖控制、手術并發癥方面的差異。 結果 B組與A組出院時，空腹血糖以及餐后血糖均能達標，但B組明顯好于A組（Plt;0.05）；B組胃排空障礙發生率降低（Plt;0.05）。 結論 胰島素泵能更好地控制血糖、減少手術并發癥的發生。【Abstract】 Objective To observe the therapeutic effect of insulin pump on type 2 diabetes mellitus combined with gastric cancer during the perioperative period. Methods Between January 2004 and December 2010, 86 patients with type 2 diabetes mellitus combined with gastric cancer were randomly divided into control group (group A, 46 cases) and insulin pump group (group B, 40 cases). The differences in blood glucose level and infection rate of operation incisions were compared between the two groups. Results Both groups reached the aimed glucose level (fasting blood glucose and postprandial blood glucose) at the discharge from the hospital, which in group B were significantly better than those in group A （Plt;0.05）. The obstruction of gastric emptying in group B decreased significantly (Plt;0.05). Conclusion Insulin pump can control the blood glucose and reduce the surgical complications．
