Alterations in Pancreatic Islet Cell Function in Response to Small Bowel Resection.

Conclusion Following massive SBR, there is significant hypertrophy of pancreatic islet cells with morphologically intact a- and b-cells. Significantly reduced pancreatic insulin release in both static and dynamic conditions demonstrate perturbed intrinsic b-cell function. GLP-1 is a key mediator of this amplification pathway. Decreased expression of serum GLP-1 and pancreatic GLP-1R in face of no change in insulin content offer a novel pathway for enteropancreatic glucose regulation following SBR.
