Archive description
Gastrointestinal rerouting through Roux-en-Y (R-Y) reconstruction reshapes gut microbiota and metabolic health in non-obese type 2 diabetes mellitus (T2DM) patients, suggesting a therapeutic potential. Here, twelve patients with early gastric cancer and T2DM underwent R-Y reconstruction after gastrectomy.
