Peri-firing compression in prevention of pancreatic fistula after distal pancreatectomy: A systematic review and a cohort study.

Abstract

Background/aims: Clinically relevant postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP) occurs in 20%-40% of patients and remains a leading cause of morbidity and increased healthcare cost in this patient group. Recently, several studies suggested decreased risk of CR-POPF with the use of peri-firing compression (PFC) technique. The aim of this report was to conduct a systematic review to get an overview of the current knowledge on the use of PFC in DP. In addition, our experience with PFC was presented.

Methods: The systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Also, 19 patients undergoing DP with the use of PFC at Oslo University Hospital were studied. The primary endpoint was incidence of CR-POPF.

Results: Seven articles reporting a total of 771 patients were ultimately included in the systematic review. Only two of these were case-control studies examining outcomes in patients with and without PFC, while the rest were case series. These were heterogeneous in terms of staplers used, cartridge selection policy, and PFC technique. Both case-control studies reported significantly reduced CR- POPF incidence with PFC. Eight (21%) of our patients developed CR-POPF after DP with PFC. Only one patient developed CR-POPF among those with pancreatic transection site thickness ⩽1.5 cm.

Conclusion: Evidence on potential benefits of PFC in DP is limited in quantity and quality. Our findings suggest that the use of PFC does not lead to reduction in the incidence of CR-POPF. Yet, there might be a benefit from PFC when dealing with a thin pancreas.
