Abstract

Postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) remains a challenge even at high-volume centers.This study was designed to analyze perioperative risk factors for POPF after PD and evaluate the factors that predict the extent and severity of leak. Demographic data, preoperative, intraoperative, and postoperative variables were collected.A total of 471 consecutive patients underwent PD in our center. Fifty-seven patients (12.1 %) developed a POPF of any type; 21 patients (4.5 %) had a fistula type A, 22 patients (4.7 %) had a fistula type B, and the remaining 14 patients (3 %) had a POPF type C. Cirrhotic liver (P = 0.05), BMI > 25 kg/m(2) (P = 0.0001), soft pancreas (P = 0.04), pancreatic duct diameter <3 mm (0.0001), pancreatic duct located <3 mm from the posterior border (P = 0.02) were significantly associated with POPF. With the multivariate analysis, both BMI and pancreatic duct diameter were demonstrated to be independent factors. The hospital mortality in this series was 11 patients (2.3 %), and the development of POPF type C was associated with a significantly increased mortality (7/14 patients). The following factors were predictors of clinically evident POPF: a postoperative day (POD) 1 and 5 drain amylase level >4,000 IU/L, WBC, pancreatic duct diameter <3 mm, and pancreatic texture.Cirrhotic liver, BMI, soft pancreas, pancreatic duct diameter <3 mm, pancreatic duct near the posterior border are risk factors for development of POPF. In addition a drain amylase level >4,000 IU/L on POD 1 and 5, WBC, pancreatic duct diameter, pancreatic texture may be predictors of POPF B, C.
