Abstract

Managing pancreatic fluid collections (PFCs) in acute pancreatitis has undergone a paradigm shift. Endoscopic and surgical advancements have led to the development of safer and more effective techniques for draining PFCs and performing necrosectomy. These techniques have been effectively incorporated into the step-up approach. Percutaneous catheter drainage remains the cornerstone for managing PFCs, although its role has changed with the advent of endoscopic ultrasound-guided techniques. PFC management relies heavily on interdisciplinary collaboration. All the techniques must be considered complementary rather than competitive. The preference for one method over the other must consider the patient factors and availability of expertise. This review entails a detailed discussion of the intervention of PFCs with the latest available evidence.
