简要总结
The distal ileum and proximal colon, where the glucagon-like peptide 1 (GLP-1) releasing cells predominate, are important organs in mediating glycemic control. The proximal colon is not easy to access and the correspond in vivo research remains to be difficult. The investigators intend to recruit subjects who underwent rectal surgery with simultaneous protective ileostomy and evaluate hormone secretion and glycemic excursions via ileostomy glucose or saline infusion, and quantify the glucose absorption rate within the proximal colon.
