Abstract

Background The aim of this study was to evaluate whether the placement of a coaxial double-pigtail plastic stent (DPS) within a lumen-apposing metal stent (LAMS) may improve the safety of endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs).

Methods This was a retrospective cohort study including patients with PFCs and an indication for transmural drainage. Two strategies (LAMS alone or LAMS plus DPS) were used at the endoscopist’s discretion.

Results A total of 41 patients were treated (21 LAMS alone; 20 LAMS plus DPS). The characteristics of the PFCs, and the technical and clinical success rates did not differ between groups. The LAMS alone group had a significantly higher rate of adverse events than the LAMS plus DPS group (42.9 % vs. 10.0 %; P = 0.04). Bleeding was the most frequent adverse event observed.

Conclusions The addition of a coaxial DPS to LAMS was associated with a lower rate of adverse events in EUS-guided drainage of PFCs.
