Serum amylase on the night of surgery predicts clinically significant pancreatic fistula after pancreaticoduodenectomy.

ABSTRACT: Drainage after pancreaticoduodenectomy (PD) remains controversial because the risk for uncontrolled postoperative pancreatic fistula (POPF) must be balanced against the potential morbidity associated with prolonged and possibly unnecessary drainage. This study investigated the utility of the level of serum amylase on the night of surgery [postoperative day (PoD) 0 serum amylase] to predict POPF.A total of 185 patients who underwent PD were studied. Occurrences of POPF were graded using the International Study Group on Pancreatic Fistula (ISGPF) classification. Receiver operating characteristic (ROC) analysis identified a threshold value of PoD 0 serum amylase associated with clinically significant POPF (ISGPF Grades B and C) in a test cohort (n = 45). The accuracy of this threshold value was then tested in a validation cohort (n = 140).Overall, 43 (23.2%) patients developed clinically significant POPF. The threshold value of PoD 0 serum amylase for the identification of clinically significant POPF was ? 130 IU/l (P = 0.003). Serum amylase of <130 IU/l had a negative predictive value of 88.8% for clinically significant POPF (P < 0.001). Serum amylase of ? 130 IU/l on PoD 0 and a soft pancreatic parenchyma were independent risk factors for clinically significant POPF.Postoperative day 0 serum amylase of <130 IU/l allows for the early and accurate categorization of patients at least risk for clinically significant POPF and may identify patients suitable for early drain removal.

Project description:BackgroundClinically relevant postoperative pancreatic fistula (CR-POPF) is a common and troublesome complication after pancreatoduodenectomy (PD). We conducted a systematic review and meta-analysis to identify the risk factors of CR-POPF after PD.MethodsWe searched PubMed, EMBASE, and Cochrane Library databases for studies related to risk factors of CR-POPF after PD. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were extracted from the included studies, then a meta-analysis was conducted. If necessary, sensitivity analysis would be performed by changing the effect model or excluding 1 study at a time. Publication bias was assessed by funnel plot and Begg test and Egger test.ResultsA total of 27 studies with 24,740 patients were included, and CR-POPF occurred in 3843 patients (incidence = 17%, 95% CI: 16%-19%). Male (OR = 1.56, 95% CI: 1.42-1.70), body mass index >25 kg/m2 (OR = 1.98, 95% CI: 1.23-3.18), pancreatic duct diameter <3 mm (OR = 1.87, 95% CI: 1.66-2.12), soft pancreatic texture (OR = 3.49, 95% CI: 2.61-4.67), and blood transfusion (OR = 3.10, 95% CI: 2.01-4.77) can significantly increase the risk of CR-POPF. Pancreatic adenocarcinoma (OR = 0.54, 95% CI: 0.47-0.61), vascular resection (OR = 0.57, 95% CI: 0.39-0.83), and preoperative chemoradiotherapy (OR = 0.68, 95% CI: 0.57-0.81) can significantly decrease the factor of CR-POPF. Diabetes mellitus was not statistically associated with CR-POPF (OR = 0.66, 95% CI: 0.40-1.08). However, the analysis of body mass index, pancreatic texture, and diabetes mellitus had a high heterogeneity, then sensitivity analysis was performed, and the result after sensitivity analysis showed diabetes mellitus can significantly decrease the risk of CR-POPF. There was no significant publication bias in this meta-analysis.ConclusionsThe current review assessed the effects of different factors on CR-POPF. This can provide a basis for the prevention and management of CR-POPF. Effective interventions targeting the above risk factors should be investigated in future studies for decreasing the occurrence of CR-POPF.
