摘要
Background/objective Biliopancreatic diversion with duodenal switch (BPD-DS) is the most effective bariatric intervention to treat morbid obesity and related disorders. Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a new bariatric procedure devised with the purpose of simplifying the complexity of the BPD-DS technique while maintaining its efficacy. However, whether BPD-DS and SADI-S result in similar fasting and post-prandial hormone profiles has not yet been studied. Therefore, the purpose of this study was to assess and compare the hormone response to a standardized mixed meal in subjects operated with BPD-DS or SADI-S. Subjects/methods Subjects submitted to BPD-DS ( n = 9) or SADI-S ( n = 9) 1.5 years earlier on average, with no past nor current diabetes diagnosis underwent a liquid mixed-meal tolerance test (MMTT) to assess the baseline and post-prandial profile of glucose, enteropancreatic hormones and total bile acids. Results Fasting glucose, enteropancreatic hormones and total bile acids levels after BPD-DS and SADI-S were similar. After the MMTT, the response of subjects who underwent SADI-S was characterized by higher glucose ( t = 30 min: p < 0.05; iAUC: 156.1 ± 46.2 vs. 103.4 ± 35.8 mmol/L × min, p = 0.02), GLP-1 ( t = 30 min: p < 0.05; iAUC: 5388 ± 3010 vs. 2959.0 ± 2146 pmol/L × min, p = 0.02), glucagon ( t = 30 min: p < 0.05; iAUC: 678.7 ± 295.2 vs. 376.9 ± 215.7 pmol/L × min, p = 0.02), insulin (t = 30 and 45 min: p < 0.05); and C-peptide levels ( t = 30 and 45 min: p < 0.05), when compared to BPD-DS. Conclusions The post-prandial hormone secretion profile after SADI-S is characterized by increased GLP-1, glucagon and insulin secretion, when compared to BPD-DS, which suggests the existence of different endocrine driven mechanisms leading to weight loss and metabolic improvement after the two procedures.
