Abstract
Pancreatic fluid collections (PFCs) commonly develop as complications of acute pancreatitis and ductal disruption due to chronic pancreatitis. In the revised Atlanta classification, PFCs were classified based on the presence of necrosis and duration following the onset of acute pancreatitis. Interventions are required in cases of symptomatic pancreatic pseudocysts or walled-off necrosis (WON). In the management of these PFCs, endoscopic ultrasound-guided transluminal drainage and subsequent direct endoscopic necrosectomy for WON are increasingly utilized as less invasive treatment modalities compared to surgical debridement. To date, researchers have focused predominantly on the technical aspects of endoscopic therapy for symptomatic PFCs. Given the poor physical condition of patients receiving endoscopic treatment for PFCs, systemic support may have a substantial impact on the short- and long-term outcomes of these patients. A multidisciplinary approach is required to improve the clinical outcomes of patients with infected PFCs and their associated comorbidities. However, non-interventional support during the periprocedural period of endoscopic treatment of PFCs has not been fully discussed, and there have been considerable variations in the selection of treatment options between endoscopists and centers. To address these unmet needs in the clinical management of PFCs and promote future research to improve the clinical outcomes, we conducted a review of the literature within a multicenter consortium of expert endoscopists with specific expertise in the endoscopic treatment of PFCs. In this review, we summarize the current evidence on non-interventional supportive care (e.g., continuous lavage, medications, nutritional support, and antimicrobials) and propose potential topics for future research.
