Background
Severe chronic kidney disease (CKD) predicts adverse outcomes in patients undergoing pancreatectomy, but the impact of milder CKD is unknown. Additionally, some authors have suggested that, due to physiologic changes of aging, CKD is over-diagnosed in patients above age 65.
Methods
Patients undergoing pancreatectomy for malignancy from 2005 to 2014 were identified from the National Surgical Quality Improvement Program. Primary outcomes were all-cause mortality and major complication, defined as myocardial infarction, cardiac arrest, stroke, venous thromboembolism, respiratory failure, deep surgical site infection, pneumonia, acute kidney injury, coma > 24 h, or re-operation occurring within 30 days of surgery.
Results
The mean age of 16,173 participants was 66 (range 18–90). Median preoperative creatinine was 0.80 mg/dL (0.10–11.0), and median preoperative eGFR was 86.36 mL/min/1.73m2 (2.98–182.2). Mortality and major complication occurred in 3 and 23% of patients, respectively. In adjusted analyses, CKD stages 2 (adjusted odds ratio (aOR) 1.24, 95% confidence interval (CI) 1.10–1.40), 3a (aOR 1.50, 95% CI 1.24–1.82), 3b (aOR 1.56, 95% CI 1.19–2.06), and 4 (aOR 2.17, 95% CI 1.25–3.76) were associated with increased major complication, and CKD stage 4 was associated with increased mortality (aOR 2.68, 95% CI 1.10–6.56). Age did not influence the relationship between CKD and either outcome.
Conclusion
CKD of any stage was associated with an increased risk of postoperative major complication, and severe CKD was associated with increased mortality among patients undergoing pancreatectomy for malignancy. These associations were not diminished in elderly patients. Our findings could inform preoperative counseling and decision-making.
