摘要目的 研究胃转流术(gastric bypass,GBP)对2型糖尿病(type 2 diabetes mellitus,T2DM)的治疗作用.方法 分析2009年9月至2010年9月在第四军医大学西京医院住院的32例T2DM患者接受GBP的临床资料,比较手术前后空腹血糖(FBG)、餐后2h血糖(2hPG)、糖化血红蛋白(HbAlc)及体质量、血压和脂肪肝的变化.结果 本组32例患者在GBP后无严重并发症.术后1、6、12个月的FBG[(7.8±2.2)mmol/L、( 7.7±2.2)mmol/L、(7.2±1.8) mmol/L]均低于术前的PBG[ (11.1±2.7)mmol/L],P＜0.05;术后l、6、12个月的2hPG[( 10.2±2.6) mmol/L、(10.5±2.8)mmol/L、(10.5±3.1)mmol/L]均低于术前的2hPG[ (14.0±3.5)mmol/L],P＜0.05；术后1、6、12个月的HbAlc[(7.6％±1.4％)、(7.5％±1.7％)、(7.1％±1.9％)]均低于术前的HbAlc[(9.0％±2.3％)],P＜0.05.BMI＜ 25 kg/m2的非超重者的术后12个月FBG[(6.9±1.5) mmol/L]、2hPG[ (10.0±3.2)mmol/L]、HbAlc[(6.9％±1.9％)]均低于术前的FBG[( 10.7±2.9) mmol/L]、2hPG[(14.3±4.1) mmol/L]、HbAlc[(8.8％±2.0％)],P＜0.05；BMI≥25 kg/m2的非超重者的术后12个月FBG[ (7.5 ±2.3)mmol/L]、2hPG[ (11.3 ±2.9)mmol/L]、HbAlc[(7.3％±1.9％)]均低于术前的FBG[ (11.7±2.3)mmol/L]、2hPG[( 13.5±2.4)mmol/L]、HbAlc[(9.2％±2.7％)],P＜0.05.6例合并有高血压的T2DM患者术后1年血压正常5例.17例合并有脂肪肝的T2DM患者术后1年脂肪肝减轻8例.结论 GBP对T2DM患者的糖代谢失常及合并症有明显的治疗作用.

abstractsObjective To evaluate gastric bypass on relieving type 2 diabetes mellitus. Methods From September 2009 to September 2010,Thirty two cases of type 2 diabetes mellitus patients underwent gastric bypass operation in Xijing Hospital.Preoperative FBG,2hPG,HbAlc,weight,blood pressure and fatty liver were compared with that on 1 month,6 months,12 months after operation. Result There was no significant postoperative complications.FBG on 1 month,6 months,12 months postop and preoperative level was respectively 7.8 ± 2.2,7.7 ± 2.2,7.2 ± 1.8 and 11.1 ± 2.7 ( mmol/L),P ＜ 0.05.2hPG was 10.2 ± 2.6,10.5±2.8,10.5 ±3.1 and 14.0 ±3.5 (mmoL/L),P＜0.05.HbAlc was 7.6％ ±1.4％,7.5％ ± 1.7％,7.1％ ±1.9％ and9.0％±2.3％,P＜0.05.FBG[(6.9±1.5) mmol/L],2hPG[(10.0±3.2) mmol/L] and HbAlc[ (6.9％ ± 1.9％ ) ] on 12 months after operation were lower than preoperative[ FBG ( 10.7 ± 2.9 ) mmol/L,2hPG ( 14.3 ± 4.1 ) mmol/L,HbAlc ( 8.8％ ± 2.0％ ) ] in patients with BMI ＜25 kg/m2 (P ＜ 0.05 ).In patients with preoperative BMI ≥ 25 kg/m2,FBG ( 7.5 ± 2.3 ) mmol/L,2hPG ( 11.3 ±2.9) mmol/L HbAlc (7.3％ ± 1.9％ ),12 mos pest were lower than that of preoperative levels of [FBG(11.7 ±2.3) mmol/L,2hPG(13.5 ±2.4) mmol/L,HbAlc(9.2％ ±2.7％)] (P ＜0.05).Postoperative blood pressure became normal in 5 out of 6 patients complicating preoperative high blood pressure as evaluated on 12 months after operation. Fatty liver ameliorated in 8 out of 17 patients.Conclusions Gastric bypass significantly improves glycometabolism and comorbidity in type 2 diabetes patients.
