This study examined the relationship between vitamin D status and quality of life measures in patients who underwent total pancreatectomy with islet autotransplantation (TP-IAT). The researchers found that 53% of patients were vitamin D deficient after surgery. Patients who were vitamin D deficient reported twice as high morphine use and higher pain scores six months after surgery compared to vitamin D sufficient patients. This suggests that vitamin D status may impact quality of life outcomes after TP-IAT surgery and monitoring vitamin D levels and supplementing as needed could help improve patient well-being and pain management.
