Drain fluid biomarkers for the diagnosis of clinically relevant postoperative pancreatic fistula - a diagnostic accuracy systematic review and meta-analysis.

The current findings using the pooled cut-offs will offer options for clinicians seeking to identify patients for quicker recovery. Improving the reporting of future diagnostic test studies will further clarify the diagnostic utility of drain fluid biomarkers, facilitating their inclusion in multi-variable risk-stratification models and the improvement of pancreatectomy outcomes.
