Details and patient eligibility

About

The distal ileum, where the glucagon-like peptide 1 (GLP-1) releasing cells predominate, is an important organ in mediating glycemic control. However, the distal ileum 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 distal ileum.
