RESUMO
Objective To evaluate the treatment outcome of laparoscopic Roux-en-Y gastric bypass on old patients (≥60 years old) 3 years after surgery.Methods The clinical data of 116 patients who underwent LRYGB from Jan.2011 to Mar.2014 were retrospectively examined.Patients were divided in two group:group≥ 60 years comprised of 46 patients,group ＜60 years comprised of 70 patients.Preoperative and postoperative weight,blood glucose,blood lipid,hypertension and complication were evaluated,and the efficacy on the two groups was compared.Results The average age of group≥60 years was (63.1±2.5)years and the mean duration of diabetes was (11.3±4.8) years.Mean weight decreased from (81.8±12.7)kg to (64.6±11.7)kg (P＜0.01),mean BMI decreased from (30.5±3.8) kg/m2 to (24.0±4.1) kg/m2 (P＜0.01),glycosylated hemoglobin(HbA1c) decreased from (9.0±2.0)％ to (7.06±126)％ (P＜0.01),and the remission of diabetes was 45.7％.Significant difference was also found in weight,BMI,EWL％,FBG,PBG,HbA1c,HOMA-IR,Ch,TG,LDL-C,hypertension at 3 years after surgery (P＜0.05),but HDL-C level was similar after the operation.There was no significant difference between group≥60 years and group ＜60 years(P＞0.05) except HbA1c(P＜0.05).The incidence of postoperative complicationswasnot statistically significant(P＞0.05).Conclusions LRYGB is a safe and effective treatment for old patients with obesity and T2DM.The remission rate of T2DM 3 years after surgery was similar between the 2 groups.
