Comparative Study
Alterations of Gut Microbiota After Roux-en-Y Gastric Bypass and Sleeve Gastrectomy in Sprague-Dawley Rats.
The objective of the study was to compare gut microbiota post Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). ⋯ RYGB, but not SG, alters the gut microbiota of Sprague-Dawley rats. RYGB also reduces the diversity of gut microbiota. Furthermore, the abundance of Gammaproteobacteria negatively correlates with postoperative body weight and may be one of the potential contributors to stable weight loss after bariatric surgery.
