%X OBJECTIVE: Total pancreatectomy with islet autotransplantation (TPIAT) is an effective treatment for patients with chronic pancreatitis (CP) when other interventions are unsuccessful. CP has many etiologies including heredity. Metabolic and pain relief outcomes after TPIAT are presented among patients with a genetic CP etiology compared with those with a nongenetic etiology in a large cohort of patients who underwent this procedure at our center.
METHODS: A retrospective analysis was performed of 237 patients undergoing TPIAT between 2006 and 2023. We analyzed the differences in patients with genetic (n = 56) vs nongenetic CP etiologies (n = 181) in terms of pre-TPIAT factors including patient characteristics and disease state, results from the isolation process, and outcomes such as long-term glycemic and pain control.
RESULTS: Patients with genetic CP underwent TPIAT at a significantly younger age (32.3 vs 41.3 years nongenetic; P < .0001) and endured symptoms for a significantly longer period (10 vs 6 years; P < .01). A significantly lower mass of islets was isolated from patients with genetic CP (P < .01), which increased with body mass index in both groups. Despite lower yields, patients with genetic CP maintained metabolic function similar to patients with nongenetic CP, as indicated by insulin independence and C-peptide, blood glucose, and hemoglobin A1C levels after TPIAT. Post-transplant narcotic usage and pain scores significantly decreased compared with those before TPIAT, and more patients with genetic CP were pain free and narcotic free after TPIAT.
CONCLUSIONS: Our data validate TPIAT as a beneficial procedure for patients enduring CP of genetic etiology. Pain that is inevitably recurrent after minor interventions owing to the nature of the disease and favorable TPIAT outcomes should be considered in the decision to perform early TPIAT in cases of genetic CP.
