Multifactorial mitigation strategy to reduce clinically relevant pancreatic fistula in high-risk pancreatojejunostomy following pancreaticoduodenectomy

Introduction: Postoperative pancreatic fistula (POPF) is the most dreadful complication of pancreaticoduodenectomy (PD) and previous literature focused on technical modifications of pancreatic remnant reconstruction. We developed a multifactorial mitigation strategy (MS) and the aim of the study is to assess its clinical impact in patients at high-risk of POPF. Methods: All patients candidate to PD between 2012 and 2018 were considered. Only patients with a high Fistula Risk Score (FRS 7-10) were included. Patients undergoing MS were compared to patients receiving Standard Strategy (SS). Clinical outcomes were compared between the two groups. Multivariate hierarchical logistic regression analyses were performed to detect independent predictors of POPF. Results: Out of 212 patients, 33 were finally included in MS Group and 29 in SS Group. POPF rate was significantly lower in MS Group (12.1% vs 44.8%, p = 0.005). Delayed gastric emptying, postoperative pancreatitis, complications and hospital stay were also significantly lower in MS Group. Hierarchical logistic regression analyses showed that Body Mass Index (OR = 1.196, p = 0.036) and MS (OR = 0.187, p = 0.032) were independently associated with POPF. Conclusion: A multifactorial MS can be helpful to reduce POPF rate in patients with high FRS following PD. Personalized approach for vulnerable patients should be investigated in the future.

Automated summary

The study suggests that the use of a multifactorial mitigation strategy (MS) following pancreaticoduodenectomy (PD) can significantly reduce the occurrence of postoperative pancreatic fistula (POPF) in high-risk patients. Both Body Mass Index and MS were identified as independent predictors of POPF. Further investigation on personalized approaches for vulnerable patients is recommended.
