腹腔镜可调节胃束带术与胃袖状切除术治疗肥胖症合并2型糖尿病的近期疗效比较

目的 比较腹腔镜下可调节胃束带术（LAGB）与腹腔镜胃袖状切除术（LSG）治疗肥胖症合并2型糖尿病的近期减重及降糖疗效,并初步分析两种术式减重与降糖疗效间的关系.方法 回顾性分析2010年1月至201 1年12月上海第二军医大学附属长海医院收治的40例肥胖症合并2型糖尿病患者的临床资料.其中行LAGB 14例（LAGB组）,行LSG 26例（LSG组）.采用门诊及远程随访的方式比较两种术式术后1年时间内的减重及降糖疗效.两组术前情况比较采用配对t检验,两组间比较采用重复测量的双变量多因素方差分析,减重及降糖疗效相关性采用线性回归分析.结果 两组患者均经腹腔镜完成手术,无中转开腹,无术中并发症发生.LAGB组患者手术时间为（69±16） min,术中出血量为（31±14） mL.LSG组患者手术时间为（120 ± 15） min,术中出血量为（148±48）mL.两组患者术后均未发生营养不良、电解质紊乱、胃排空障碍、出血、吻合口漏等严重并发症.有2例患者术后出现局部伤口脂肪液化,经换药后愈合.（1）减重疗效：LAGB组和LSG组患者术后体质量、BMI、腰围均呈下降趋势.LAGB组患者术后体质量、BMI、腰围由术前的（117 ±28）kg、（40±8）kg/m2、（118±15）cm下降为术后48周的（94±28）kg、（33±8）kg/m2、（92±15） cm;LSG组患者上述指标由术前的（119±25）kg、（42±6） kg/m2、（123±14） cm下降为术后48周的（74±16） kg、（26±4） kg/m2、（86±13）cm.两组患者多余体质量减少率（EWL）呈上升趋势.LAGB组患者EWL由术后1周7％±2％上升为术后48周的53％±24％,LSG组患者EWL由术后1周11％±4％上升为术后48周的90％±20％.两组上述指标变化趋势比较,差异有统计学意义（F=60.660,74.490,57.650,90.020,P＜0.05）.（2）降糖疗效：LAGB组患者术后糖化血红蛋白、空腹血糖、空腹胰岛素、胰岛素抵抗指数、TG、TC、LDL、HDL由术前的8.1

Comparison of the short-term efficacies of laparoscopic adjustable gastric banding and laparoscopic sleeve gastrectomy in the treatment of obesity combined with type 2 diabetes mellitus

Objective To compare the short-term efficacies of laparoscopic adjustable gastric banding （LAGB） and laparoscopic sleeve gastrectomy （LSG） in the treatment of obesity and type 2 diabetes mellitus,and to investigate the relationship between the body weight loss and the decrease of glucose of the 2 treatment methods.Methods The clinical data of 40 patients with obesity combined with type 2 diabetes mellitus who were admitted to the Changhai Hospital of the Second Military Medical University from January 2010 to December 2011 were retrospectively analyzed.There were 14 patients treated by LAGB （LAGB group） and 26 by LSG （LSG group）.The body weight loss and the decrease of glucose at postoperative year 1 of the 2 groups were compared.The differences in the body weight and glucose before and after operation within groups were compared using the paired t test,and the differences in the body weight and glucose between the 2 groups were compared using the multiple analysis of variance.The correlation between the body weight loss and the decrease of glucose was analyzed using the linear regression analysis.Results Laparoscopic surgery was successfully done without conversion to open surgery or intraoperative complications.The operation time and volume of blood loss were （69 ± 16）minutes and （31 ± 14）mL in the LAGB group,（120 ± 15） minutes and （148 ± 48） mL in the LSG group.Complications including postoperative malnutrition,electrolyte disturbance,delayed gastric emptying,bleeding,anastomotic leakage did not occurr in the 2 groups.Two patients were complicated with abdominal incision fat liquefaction,and were cured by symptomatic treatment.（1） The body weight,body mass index （BMI） and waistline had a decrease trend.The body weight,BMI and waistline in the LAGB group were decreased from （117 ± 28）kg,（40 ± 8）kg/m2 and （118 ± 15） cm before operation to （94 ± 28） kg,（33 ± 8） kg/m2 and （92 ± 15） cm at postoperative week 48.The body weight,BMI and waistlin
