Total pancreatectomy with islet autotransplantation reduces opioid use and improves nutritional support in children with debilitating pancreatitis.

BACKGROUND

Chronic pancreatitis (CP) can result in opioid dependence and nutritional challenges in children. Total pancreatectomy with islet autotransplantation (TPIAT) is a viable surgical option in appropriately selected patients. We examined differences between children who met criteria for TPIAT versus those who did not and continued with non-operative management.

METHODS

Retrospective observational cohort study of patients evaluated for TPIAT between August 2014 and July 2020 was performed. Cohort-based analyses between TPIAT and non-TPIAT groups were performed.

RESULTS

Analyses included 121 patients, 69 of whom underwent TPIAT. Demographics, genetic risk factors, and anatomic variants did not differ between groups. TPIAT patients were more likely to have CP (88% vs 71%; p = 0.02), had higher median number of endoscopic retrograde cholangiopancreatography procedures (2.0 vs 1.0; p = 0.0001), and had higher likelihood of opioid use (61% vs 42%; p = 0.04) and nutritional supplementation (23% vs 4%; p = 0.004), compared to non-TPIAT. At 6 months post-TPIAT, patients had lower use of any analgesic pain medications (39% vs 73%; p = 0.0002) and lower use of opioids (9% vs 39%; p = 0.0006), compared to non-TPIAT patients at 6 months after evaluation. At 6 months post-TPIAT, rate of exclusively oral nutrition increased from 77% to 86%, and total parenteral nutrition use decreased from 13% to 0% (p = 0.02).

CONCLUSIONS

In children referred for TPIAT evaluation, there is greater burden of disease in those selected for operation, compared to patients who do not undergo operation. TPIAT achieves lower analgesic pain medication use compared to continuation with non-TPIAT management and achieves freedom from nutritional supplementation. Level of evidence: Retrospective comparative study, Level III.
