Aim: To assess the correlations among pancreatic fibrosis, pancreatic stiffness, and postoperative pancreatic fistula (PF). Patients and Methods: The study population consisted of 17 consecutively enrolled patients who underwent subtotal stomach-preserving pancreaticoduodenectomy (SSPPD). The liver fibrosis (LF) index as pancreatic stiffness was measured by real- time tissue elastography (RTE) before SSPPD. We also obtained the pathological fibrosis assessment of the pancreatic stump after SSPPD. Results: The LF index was significantly correlated with pathological pancreatic stump fibrosis. The LF index of patients without PF was significantly higher than that of patients with PF. The optimal cut-off value of the LF index to predict postoperative PF was defined as an LF index ≤1.91. Multivariate analysis revealed that a preoperative LF index ≤1.91 was an independent predictive factor of postoperative PF. Conclusion: Evaluation of pancreatic stiffness using RTE might be an objective index to estimate pancreatic fibrosis and predict postoperative PF.
