    Area of Science:

    • Surgical Innovation
    • Biomaterials Science
    • Endocrinology

    Context:

    • Pancreatic transplantation necessitates managing exocrine secretions.
    • Existing methods for exocrine function management have limitations.

    Purpose:

    • To evaluate polyurethane as a novel agent for pancreatic duct occlusion.
    • To assess the functional, morphological, and outcome effects of polyurethane-induced exocrine atrophy.

    Summary:

    • Polyurethane solution was injected into the pancreatic duct in a canine model, causing complete exocrine tissue atrophy and fibrosclerosis.
    • Islets remained well-vascularized and functional, with animals maintaining normoglycemia and normal hormonal levels (insulin, glucagon, somatostatin).
    • Amylase levels normalized within two weeks post-occlusion, indicating successful exocrine function elimination without endocrine disturbance.
