NEJM:胃旁路术后12年体重及代谢变化

2017-09-21 zhangfan MedSci原创

研究表明Roux-en-Y胃旁路术具有长期耐久的减肥效果,可有效缓解和预防2型糖尿病,高血压和血脂异常

减肥手术后长期或对照研究十分罕见。近日研究人员开展了一项为期12年的随访对照研究,考察Roux-en-Y胃旁路术对肥胖患者体重及代谢的影响。

总计1156名严重肥胖患者分成3组:418人进行Roux-en-Y胃旁路手术(手术组)、417人计划但因保险原因未进行手术(非手术1组)、321人不进行手术干预(非手术2组)。在基线、术后2、6、12年对参与者的II型糖尿病、高血压和血脂异常进行考察。

12年的随访完成率超过90%。研究发现,调整后的平均体重差异手术组与非手术组如下:2年:-45.0kg(95%,CI,-47.2--42.9,平均变化百分比-35.0);6年:-36.3kg(95%,CI,-39.0--33.5,平均变化百分比-28.0); 12年:-35.0kg(95%,CI,-38.4--31.7;平均变化百分比-26.9)。非手术1组12年的平均体重减少2.9kg,非手术2组的平均体重无变化。对于手术组基线患有II糖尿病的患者,75%的患者在术后2年糖尿病得到缓解,6年缓解率为62%,12年的缓解率为51%。相比于非手术1组和2组,手术组12年的II型糖尿病风险分别为0.08和0.09。相对于非手术组1,手术组有较高的高血压缓解率与较低的血脂异常的发生率。

研究表明Roux-en-Y胃旁路术具有长期耐久的减肥效果,可有效缓解和预防2型糖尿病,高血压和血脂异常。

DRCP:Roux-en-Y胃旁路术可改善肥胖患者心血管功能

为了评估伴有2型糖尿病(T2DM)和高血压的肥胖患者腹腔镜Roux–en–Y胃旁路术(RYGB)疗效,并与用和不用艾塞那肽治疗的常规护理的相比较,来自第三军医大学西南医院内分泌科梁自文教授及其团队进行了一项研究,发现RYGB手术可改善伴有T2DM的肥胖高血压患者包括心血管功能在内的若干参数。该研究结果发表在2013年7月的Diabetes Research and Clinical Practic

胃旁路术与胆胰转流术均能较好控制糖尿病大鼠血糖水平

  日前,上海交通大学附属上海第六人民医院普外科狄建忠、韩晓东、张宏玮等人共同发表论文,旨在比较胃旁路术(GBP)与胆胰转流术(BPD)对非胰岛素依赖性糖尿病大鼠的治疗效果,探讨其机制。研究指出,GBP和BPD均能较好地控制糖尿病大鼠的血糖水平,其机制可能与瘦素的降低及IGF-1的升高有关。GBP在手术时间、死亡率及增加血IGF-1水平等方面优于BPD。该文发表在2011年第11卷第5期《中华胰腺
