Standard LAMS Removal with Double-Pigtail Plastic StentStandard LAMS Removal without DPT

Standard LAMS Removal with Double-Pigtail Plastic Stent: In the early stent removal arm, LAMS will be removed at 2 weeks followed by placement of a double-pigtail plastic stent (DPT).

Standard LAMS Removal without DPT: In the standard arm, LAMS will be removed at 4 weeks.

Study summary

In adults with walled-off pancreatic necrosis (WON) undergoing endoscopic ultrasound (EUS)-guided transluminal necrosectomy, does early removal of the lumen-apposing metal stent (LAMS) (at 2 weeks or immediately after the last necrosectomy) with placement of a double-pigtail plastic stent (DPT), compared to delayed LAMS removal at 4 weeks without a DPT, result in a lower rate of pancreatic fluid collection (PFC) recurrence or need for reintervention over 12 months.

Healthy volunteers

Inclusion Criteria: * Age ≥18 years * Patients with walled-off pancreatic necrosis (WON) undergoing endoscopic ultrasound-guided drainage with lumen-apposing metal stent (LAMS) * Radiological resolution of the pancreatic fluid collection ≥70% at 2 weeks after index endoscopic drainage, assessed on cross-sectional imaging (CT or MRI) Exclusion Criteria: * Presence of chronic pancreatitis * Pancreatic malignancy (suspected or confirmed) * Incomplete endoscopic necrosectomy or persistent large necrotic debris on imaging at 2 weeks after drainage * Occurrence of major procedure-related adverse events within the first 2 weeks, including: * Clinically significant bleeding * Infection requiring additional intervention * Stent migration * Inability or unwillingness to provide written informed consent

Primary outcome measure(s)

Recurrence of Pancreatic Fluid Collection (PFC) — 12 months after initial drainage procedure
Recurrence is defined as the redevelopment of a symptomatic pancreatic fluid collection confirmed on imaging (CT or MRI) after initial resolution following endoscopic drainage and lumen-apposing metal stent (LAMS) removal. The recurrence rate will be compared between the early LAMS removal + double-pigtail plastic stent (DPT) group and the standard 4-week LAMS removal group.
