OBJECTIVETo evaluate the effect of removal of the duodenum on the complex interplay between incretins , insulin , and glucagon in nondiabetic subjects . RESEARCH DESIGN AND METHODSFor evaluation of hormonal secretion and insulin sensitivity , 10 overweight patients without type 2 diabetes ( age 61 +/- 19 . 3 years and BMI 27 . 9 +/- 5 . 3 kg / m ( 2 ) ) underwent a mixed - meal test and a hyperinsulinemic - euglycemic clamp before and after pylorus - preserving pancreatoduodenectomy for ampulloma . RESULTSAll patients experienced a reduction in insulin ( P = 0 . 002 ) , C - peptide ( P = 0 . 0002 ) , and gastric inhibitory peptide ( GIP ) secretion ( P = 0 . 0004 ) , while both fasting and postprandial glucose levels increased ( P = 0 . 0001 ) ; GLP - 1 and glucagon responses to the mixed meal increased significantly after surgery ( P = 0 . 02 and 0 . 031 ) .
