Diagnostic Accuracy of Lipase as Early Predictor of Postoperative Pancreatic Fistula: Results from the LIPADRAIN study

Year: 2024

Type: article

Abstract: Objective: To evaluate the diagnostic accuracy of drain fluid lipase as an early predictor of postoperative pancreatic fistula and establish the most appropriate day for their measure. Background: Clinically relevant postoperative pancreatic fistula remains a potentially life-threatening complication after pancreatic surgery. Early detection strategies remain key to reduce both the incidence and the burden of pancreatic fistula. Methods: The LIPAse DRAIN (LIPADRAIN) study is a multicenter, prospective diagnostic study conducted in 7 tertiary university hospitals. Drain fluid values to detect clinically relevant postoperative pancreatic fistula from postoperative day 1 to postoperative day 6 were evaluated using receiver operating characteristic curve analysis. A biomarker was considered to be relevant for clinical use if its area under the curve (AUC) was greater than 0.75. Results: Of the 625 patients included in the analysis, clinically relevant postoperative pancreatic fistula occurred in 203 (32%) patients. On postoperative days 3 and 4, drain fluid lipase was a reliable biomarker to detect clinically relevant postoperative pancreatic fistula (AUC: 0.761; 95% confidence interval [CI]: 0.761-0.799 and AUC: 0.784; 95% CI: 0.743-0.821, respectively). On postoperative day 3, with a threshold of 299 units/L, drain fluid lipase yielded a negative predictive value of 51%, sensitivity of 78%, and specificity of 63% for the detection of clinically relevant postoperative pancreatic fistula. Conclusions: In this multicenter prospective study, drain fluid lipase is a reliable biomarker at postoperative days 3 and 4 for the diagnosis of clinically relevant postoperative pancreatic fistula after pancreatic surgery and should be systematically measured on postoperative day 3.
