INTRODUCTION: Pancreaticoduodenectomy (PD) has a high morbidity rate. Previous work has shown that hypoalbuminemia on postoperative day 1 (POD) to be contributory to post-esophagectomy complications. We set out to determine the impact of blood urea nitrogen (BUN) and albumin on POD 1 for patients undergoing PD. METHODS: We examined 446 consecutive patients who underwent PD at the Thomas Jefferson University Hospital between January 1, 2000 and December 31, 2008. Complications were graded using the Clavien scale. We examined the incidence of complications based on POD 1 albumin <2.5 versus ≥2.5 mg/dl, as well as POD 1 BUN <10 vs. ≥10 g/dL. RESULTS: Patients with a BUN <10 had a significantly decreased risk of any complication (p < 0.001), serious complication (p < 0.001), and pancreatic fistula (p = 0.011). On multivariate analysis, BUN ≥ 10 was the most significant predictor of grade III or above complication (p = 0.0019, hazard ration (HR) = 2.7) and pancreatic fistula (p = 0.016, HR = 2.6). POD 1 albumin <2.5 mg/dl was also an independent predictor of serious complication (p = 0.01, HR = 2.3). Patients with both risk factors had a 31 % chance of developing serious complications and 18.5 % risk of developing pancreatic fistula, while those patients with neither risk factor had a 6.5 and 3.6 % risk, respectively. CONCLUSION: Serum albumin and BUN on POD 1 are important predictors of perioperative morbidity following PD. These low-cost and easily accessible tests can be used as a prognostic tool to predict adverse surgical outcomes.
