A preferable modality for the differentiation of peripancreatic fluid collections: Endoscopic ultrasound.

ABSTRACT:

Background and objectives

Peripancreatic fluid collections (PFCs), including walled-off necrosis (WON) and pancreatic pseudocysts (PPCs), are categorized by imaging modalities, including EUS, computed tomography (CT), and magnetic resonance imaging. Our study aimed to evaluate the effectiveness of EUS in differentiating PFCs compared with that of other modalities.

Subjects and methods

Data were collected retrospectively from 99 patients at fourteen centers who were recruited to undergo lumen-apposing metal stent placement to treat PFCs.

Results

PFCs were detected by CT and EUS in 51 WON and 48 PPC patients. The accuracy in differentiating PFCs by EUS was much higher than that of CT (90.9% vs. 50.5%, P < 0.001). The accuracy in identifying WON on EUS was much higher th
