Abstract

Postoperative pancreatic fistula (POPF) is a potentially debilitating complication following pancreatoduodenectomy (PD). There are limited data correlating pancreatic parenchymal histopathologic features specifically fat and fibrosis content with development of POPF after PD. Patients who underwent PD (January 2010-May 2015) with archived pathologic slides were included. Each pancreatic neck transection margin was histologically graded for fat and fibrosis, scored from 0 to 4, and grader was blinded to clinical outcomes. Main pancreatic duct diameter and duct wall thickness were microscopically measured. Patients were dichotomized into high and low categories with respect to pancreatic fat and fibrosis and primary outcome of POPF. Of 301 patients, 24 developed POPF (8.0%). One hundred ten patients (36.5%) had low fat (score <2), and 149 (49.5%) had low fibrosis (score <2), and average duct diameter was 3.9 ± 1.3 mm. Patients with low fibrosis had a higher rate of POPF (12.8% versus 3.3%, P = 0.005). Low fibrosis (odds ratio [OR] 4.29, 95% confidence interval [CI] 1.56-11.7, P = 0.005), nonpancreatic adenocarcinoma pathology (OR 3.25, 95% CI 1.25-8.43, P = 0.02), and increased body mass index (BMI) (OR 1.11, 95% CI 1.03-1.12, P ...Continue Reading
