    Pancreaticoduodenectomy (PD) alters nutrient transit and may modify incretin hormone secretion involved in glucose homeostasis.

  • 2

    Postprandial GLP-1 levels generally increase after PD, particularly in conditions with faster gastric emptying and greater distal nutrient exposure.

  • 3

    GIP levels showed less consistent enhancement after PD, with fewer studies reporting on this hormone compared to GLP-1.

  • 4

    Exploratory meta-analysis suggested a potential favoring of Whipple reconstruction for early GLP-1 exposure, but findings were fragile.

  • 5

    The review emphasizes the need for larger prospective studies with standardized protocols to better understand incretin responses after PD.
