Impact of Gastroparesis on Outcomes After Pancreas Transplantation

Abstract

Background: Gastroparesis (GP) is a chronic disorder of the stomach characterized by delayed gastric emptying and frequently associated with longstanding diabetes. This is a single-center retrospective analysis designed to establish the prevalence and assess the impact on posttransplant outcomes of GP among pancreas transplant recipients. Methods: Medical records for all recipients of pancreas transplants performed between January 2003 and December 2023 were reviewed. GP was defined by abnormal gastric-emptying scintigraphy or other motility study or a history of symptoms. Primary outcomes included graft loss and patient death. Clinical outcomes included length of stay after transplant and readmissions, including specifically for GP symptoms. Results: Of 731 recipients, 156 (21%) were diagnosed with GP before transplant. Patients with GP were younger and more likely to be female individuals. Posttransplant, there was no difference in length of stay, graft survival, or patient survival. Patients with GP were more likely to be readmitted and to be specifically admitted for GP symptoms. Requirement for interventions was more common in patients with GP. Conclusions: GP is identified with increased frequency among the specific patient population referred for pancreas transplant, and although it does not seem to affect allograft or patient survival, it does seem to have an impact on readmissions and the need for interventions.
