The effects of different types of subtotal gastrectomy on the secretion of insulin and gastrin / 第三军医大学学报

ABSTRACT

Blood samples were collected from 10 cases with Billroth Ⅰ gastrectomy(BI),15 cases with Billroth Ⅱ gstrectomy(BⅡ),and 15 cases with pyloroantral flap preserving gastrectomy(PAFPG)were examined to evaluate the changes of plasma insulin and serum gastrin.The blood samples of 8 normal subjects were examined likewise to serve as control.The blood samples were collected in intervals before and after the subject had taken hypertonic glucose solution.It was found that plasma insulin was significantly higher in BⅠ and BⅡ group than in PAFPG group,but it showed no significant difference between the PAFPG group and the control.Serum gastrin was signficantly higher in PAFPG group,BⅠ group,and the control than in BⅡ group.These findings suggest that the changes of insulin and gastrin secretion vary with the type of subtotal gastrectomy.
