Age-related risks of complications after distal pancreatectomy for neuroendocrine and cystic neoplasms

Abstract

Background: Distal pancreatic neuroendocrine tumors (PNET) and pancreatic cystic neoplasms (PCN) are often incidentally found in older adults, requiring careful consideration between operative management and watchful waiting. This study analyzes the short-term complications associated with distal pancreatectomy (DP) for PNET and PCN in older adults to inform clinical decision-making.

Methods: Patients undergoing DP for PNET and PCN were analyzed using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database and the pancreatectomy procedure-targeted dataset. Associations between decade of age and 30-day outcomes were evaluated.

Results: 1626 patients were analyzed from 2014 to 2015. 692 (42.6%) were younger than 60 years, 507 (31.2%) were sexagenarians, 342 (21.0%) were septuagenarians, and 85 (5.2%) were octogenarians. Minimally invasive approaches were used in 62.7%. While septuagenarians and octogenarians constituted 26.3% of the cohort, they were affected by 55.6% of reintubations, 66.7% of failures to wean, 82.4% of myocardial infarctions, and 57.1% of septic shock. Septuagenarians and octogenarians had longer hospital stays, as compared to those younger than 60 years.

Conclusion: Septuagenarians and octogenarians are disproportionately affected by perioperative complications after DP for PNET and PCN. Careful patient selection and thorough counseling should be provided when surgery is considered.
