Roux-en-Y gastric bypass (LRYGB) has weight-independent effects on glycemia in obese type 2 diabetic patients, whereas sleeve gastrectomy (LSG) is less well characterized. This study aims to compare early weight-independent and later weight-dependent glycemic effects of LRYGB and LSG.
Eighteen LRYGB and 15 LSG patients were included in the study. Glucose, insulin, GLP-1, and GIP levels were monitored during a modified 30 g oral glucose tolerance test before surgery and 2 days, 3 weeks, and 12 months after surgery. Patients self-monitored glucose levels 2 weeks before and after surgery.
Postoperative fasting blood glucose decreased similarly in both groups (LRYGB vs. SG; baseline-8.1 ± 0.6 vs. 8.2 ± 0.4 mmol/l, 2 days-7.8 ± 0.5 vs. 7.4 ± 0.3 mmol/l, 3 weeks-6.6 ± 0.4 vs. 6.6 ± 0.3 mmol/l, respectively, P < 0.01 vs. baseline for both groups; 12 months-6.6 ± 0.4 vs. 5.9 ± 0.4, respectively, P < 0.05 for LRYGB and P < 0.001 for LSG vs. baseline, P = ns between the groups at all times). LSG, but not LRYGB, showed increased peak insulin levels 2 days postoperatively (mean ± SEM; LSG + 58 ± 14%, P < 0.01; LRYGB - 8 ± 17%, P = ns). GLP-1 levels increased similarly at 2 days, but were higher in LRYGB at 3 weeks (AUC; 7525 ± 1258 vs. 4779 ± 712 pmol × min, respectively, P < 0.05). GIP levels did not differ. Body mass index (BMI) decreased more after LRYGB than LSG (- 10.1 ± 0.9 vs. - 7.9 ± 0.5 kg/m, respectively, P < 0.05).
LRYGB and LSG show very similar effects on glycemic control, despite lower GLP-1 levels and inferior BMI decrease after LSG.
Roux-en-Y 胃旁路术(LRYGB)对肥胖 2 型糖尿病患者的血糖具有与体重无关的作用,而袖状胃切除术(LSG)的作用则不太明确。本研究旨在比较 LRYGB 和 LSG 的早期与晚期与体重无关的血糖作用。
研究纳入了 18 例 LRYGB 和 15 例 LSG 患者。在手术前和手术后 2 天、3 周和 12 个月进行改良 30g 口服葡萄糖耐量试验时,监测血糖、胰岛素、GLP-1 和 GIP 水平。患者在手术前后 2 周内自行监测血糖水平。
两组术后空腹血糖均相似下降(LRYGB 组与 LSG 组:基线-8.1±0.6mmol/L 与 8.2±0.4mmol/L,2 天-7.8±0.5mmol/L 与 7.4±0.3mmol/L,3 周-6.6±0.4mmol/L 与 6.6±0.3mmol/L,两组均 P<0.01 与基线相比;12 个月-6.6±0.4mmol/L 与 5.9±0.4mmol/L,LRYGB 组 P<0.05,LSG 组 P<0.001 与基线相比,两组间任何时间点 P=ns)。与 LRYGB 相比,LSG 在术后 2 天显示出更高的胰岛素峰值水平(均值±SEM;LSG+58±14%,P<0.01;LRYGB-8±17%,P=ns)。GLP-1 水平在 2 天内相似增加,但在 3 周时 LRYGB 更高(AUC;7525±1258 与 4779±712pmol×min,分别为 P<0.05)。GIP 水平无差异。LRYGB 术后体重指数(BMI)下降幅度大于 LSG(-10.1±0.9kg/m2 与-7.9±0.5kg/m2,P<0.05)。
尽管 LSG 术后 GLP-1 水平较低且 BMI 下降幅度较差,但 LRYGB 和 LSG 对血糖控制的影响非常相似。
