Abstract
PURPOSE Sleeve gastrectomy with transit bipartition (SG-TB) could be an attractive alternative to Roux-en-Y gastric bypass (RYGB) on weight loss and improvement of comorbidities in patients with obesity. However, there is little long-term data. Translational research on a rat model could allow long-term projection to assess efficacy and safety of SG-TB. The aim of this research was to evaluate the long-term efficacy and safety of SG-TB compared to RYGB and SHAM in rat model. MATERIALS AND METHODS Ninety-four male obese Wistar rats were distributed into 3 groups: SG-TB (n = 34), RYGB (n = 32), and SHAM (control group, n = 28). The percentage of total weight loss (%TWL), coprocalorimetry, glucose and insulin tolerance test, insulin, GLP-1, PYY, and GIP before and after surgery were assessed. The animals were followed over 6 months (equivalent to 16 years in humans). RESULTS At 6 months, %TWL was significantly greater(p = 0.025) in the SG-TB group compared to the RYGB group. There was no difference between the groups (p = 0.86) in malabsorption 15 and 120 days postoperatively. Glucose tolerance was significantly improved (p = 0.03) in the SG-TB and RYGB groups compared to the preoperative state. Insulin secretion, at 3 months, was significantly more important in the SG-TB group (p = 0.0003), compared to the RYGB and SHAM groups. GLP-1 secretion was significantly increased in the SG-TB and RYGB groups compared to the preoperative state (p = 0.001) but similar between SG-TB and RYGB animals (p = 0.72). CONCLUSION In a rat model, at long term compared to RYGB, SG-TB provides greater and better-maintained weight loss and an increased insulin secretion without impairing nutritional status.
