As obesity and type II diabetes continue to rise, bariatric surgery offers a solution, but few long-term studies are available. The purpose of this study was to evaluate the long-term outcomes of diabetic patients after gastric bypass.
This was a retrospective cohort study of all diabetic patients undergoing gastric bypass at our institution, from 1998 to 2012. Patients were compared by postoperative diabetic response to treatment (i.e., response = off oral medication/insulin versus refractory = on oral medication/insulin) and followed at 1-, 3-, 5-, and 10-y intervals. Continuous data were analyzed using Student t-test or Wilcoxon rank-sum test. Multivariable, Cox proportional hazard regression model was performed to compute diabetic cure ratios and 95% confidence intervals.
A total of 2454 bariatric surgeries were performed at our institution during the time period. A total of 707 diabetic patients were selected by Current Procedural Terminology codes for gastric bypass. Mean follow-up was 2.1 y. Incidence of diabetic response was 56% (1 y), 58% (3 y), 60% (5 y), and 44% (10 y). Postoperatively, responsive patients experienced greater percentage of total body weight loss (1 y [P < 0.0001], 3 y [P = 0.0087], and 5 y [P = 0.013]), and less hemoglobin A1c levels (1 y [P = 0.035] and 3 y [P = 0.040]) at follow-up than refractory patients. Multivariable analysis revealed a significant, independent inverse trend in incidence of diabetic cure as both age and body mass index decreased (Ptrend = 0.0019 and <0.0001, respectively). In addition, degenerative joint disease was independently associated with responsive diabetes (cure ratio = 1.6 [95% confidence interval = 1.1-2.2]).
At follow-up, both groups in our study experienced substantial weight loss; however, a greater loss was observed among the response group. Further research is needed to evaluate methods for optimizing patient care preoperatively and improving patient follow-up.
随着肥胖症和 II 型糖尿病的不断增加，减重手术提供了一种解决方案，但目前可用的长期研究很少。本研究的目的是评估胃旁路术后糖尿病患者的长期结果。
这是一项对我院 1998 年至 2012 年所有接受胃旁路手术的糖尿病患者进行的回顾性队列研究。根据术后糖尿病治疗反应（即反应=停用口服药物/胰岛素与难治性=口服药物/胰岛素）将患者进行比较，并在 1、3、5 和 10 年时进行随访。使用学生 t 检验或 Wilcoxon 秩和检验分析连续数据。使用多变量 Cox 比例风险回归模型计算糖尿病治愈率和 95%置信区间。
在研究期间，我院共进行了 2454 例减重手术。根据胃旁路术的当前程序术语代码，共选择了 707 例糖尿病患者。平均随访时间为 2.1 年。糖尿病反应发生率为 56%（1 年）、58%（3 年）、60%（5 年）和 44%（10 年）。术后，反应性患者的体重总减轻百分比更高（1 年[P<0.0001]、3 年[P=0.0087]和 5 年[P=0.013]），且血红蛋白 A1c 水平更低（1 年[P=0.035]和 3 年[P=0.040]）。多变量分析显示，随着年龄和体重指数的降低，糖尿病治愈率呈显著、独立的反向趋势（Ptrend=0.0019 和<0.0001）。此外，退行性关节病与反应性糖尿病独立相关（治愈率=1.6[95%置信区间=1.1-2.2]）。
在随访时，我们研究中的两组患者都经历了显著的体重减轻；然而，反应组的体重减轻更大。需要进一步研究以评估术前优化患者护理和改善患者随访的方法。
