Abstract:
Objective:To analyze the risk factors for postoperative pancreatic fistula after pancreaticoduodenectomy (PD).Methods:The clinical data of 185 patients undergoing PD who were admitted to the Hepatobiliary and Pancreatic Surgery Center of First Affiliated Hospital of Anhui Medical University from January 2014 to December 2018 were retrospectively analyzed. Risk factors for pancreatic fistula after PD were investigated using univariate and multivariate logistic regression analyses.Results:Among 185 patients, pancreatic fistula occurred in 37 patients after PD, and the incidence was 20.0%. Of 34 patients (18.4%) developed grade B pancreatic fistula, and 3 patients (1.6%) developed grade C pancreatic fistula. There were two deaths directly related to postoperative pancreatic fistula (5.4%). Patients with grade B and C postoperative pancreatic fistula had significantly increased hospitalization time and medical expenses. Univariate analysis identified that pancreatic duct diameter ≤3 mm, soft pancreas and serum albumin ≤30 g/L(χ 2=7.236, 6.948, 8.063, all P<0.05) were risk factors for pancreatic fistula after PD. Multivariate logistic regression analysis identified that pancreatic duct diameter≤3mm, soft pancreatic texture and serum albumin ≤30 g/L ( OR=0.401, 0.629, 0.326, 95% CI 0.167-0.968, 0.411-0.963, 0.150-0.711, all P<0.05) were independent risk factors for pancreatic fistula after PD. Postoperative pancreatic fistula patients had a median survival time of 827.0 days, 1-year survival rate was 94.7%, and a 3-year survival rate was 35.8%. There was no significant correlation between postoperative pancreatic fistula and postoperative survival(χ 2=1.367, P=0.242). Conclusions:Patients with a smaller pancreatic duct diameter (≤3 mm), soft pancreatic texture, and low postoperative albumin(≤30 g/L) may have a high incidence of pancreatic fistula after PD. Postoperative pancreatic fistula did not significantly affect the patients′ long-term survival.
