【摘要】 目的 观察糖尿病合并胃癌围手术期患者应用胰岛素泵的治疗效果。 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，将患者随机分为常规组（A组）46例和胰岛素泵组（B组）40例，比较两组患者在血糖控制、手术并发症方面的差异。 结果 B组与A组出院时，空腹血糖以及餐后血糖均能达标，但B组明显好于A组（Plt;0.05）；B组胃排空障碍发生率降低（Plt;0.05）。 结论 胰岛素泵能更好地控制血糖、减少手术并发症的发生。【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．
