Preoperative CT anthropometric measurements and pancreatic pathology increase risk for postoperative pancreatic fistula in patients following pancreaticoduodenectomy.

Abstract

Postoperative pancreatic fistula (POPF) is a common complication following pancreaticoduodenectomy (PD). However, risk factors for this complication remain controversial. We conducted a retrospective analysis of 107 patients who underwent PD. POPF was diagnosed in strict accordance with the definition of the 2016 update of pancreatic fistula from the International Study Group on Pancreatic Fistula (ISGPF). Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for POPF. A total of 19 (17.8%) subjects of pancreatic fistula occurred after PD, including 15 (14.1%) with grade B POPF and 4 (3.7%) with grade C POPF. There were 33 (30.8%) patients with biochemical leak. Risk factors for POPF (grade B and C) were larger area of visceral fat (odds ratio [OR], 1.40; p = 0.040) and pathology other than pancreatic adenocarcinoma or pancreatitis (OR, 12.45; p = 0.017) in the multivariate regression analysis. This result could assist the surgeon to identify patients at a high risk of developing POPF.
