Abstract
BACKGROUND
Total pancreatectomy with islet autotransplant (TPIAT) can improve quality of life for individuals with pancreatitis but creates health risks including diabetes, exocrine insufficiency, altered intestinal anatomy and function, and asplenia.
METHODS
We studied survival and causes of death for 693 patients who underwent TPIAT between 2001 and 2020, using the National Death Index with medical records to ascertain survival after TPIAT, causes of mortality, and risk factors for death. We used Kaplan Meier curves to examine overall survival, and Cox regression and competing-risks methods to determine pre-TPIAT factors associated with all-cause and cause-specific post-TPIAT mortality.
RESULTS
Mean age at TPIAT was 33.6 years (SD = 15.1). Overall survival was 93.1% (95% CI 91.2, 95.1%) 5 years after surgery, 85.2% (95% CI 82.0, 88.6%) at 10 years, and 76.2% (95% CI 70.8, 82.3%) at 15 years. Fifty-three of 89 deaths were possibly related to TPIAT; causes included chronic gastrointestinal complications, malnutrition, diabetes, liver failure, and infection/sepsis. In multivariable models, younger age, longer disease duration, and more recent TPIAT were associated with lower mortality.
CONCLUSIONS
For patients undergoing TPIAT to treat painful pancreatitis, careful long-term management of comorbidities introduced by TPIAT may reduce risk for common causes of mortality.
