A Critical Narrative Review of Coaxial Double-Pigtail Stenting Within the LAMS in the Management of Pancreatic Fluid Collections.

Endoscopic ultrasound (EUS)-guided drainage using lumen-apposing metal stents (LAMSs) has become the standard for managing pancreatic fluid collections (PFCs), especially walled-off necrosis (WON). However, LAMS-specific adverse events (AEs), including bleeding, stent occlusion, and infection, remain a concern. To mitigate these complications, some experts advocate placing coaxial double-pigtail plastic stents (DPPSs) within LAMSs.

Management of anastomotic leaks is patient-specific and surgical management is dictated by the degree of contamination, inflammation, and patient risk factors. Internal drainage with double pigtail stents - initially used for managing leaks after bariatric surgery - has recently been applied to anastomotic leaks following resection of colorectal malignancies.

Background & Aims: Endoscopic ultrasound-guided biliary drainage, creating a choledochoduodenostomy and using lumen-apposing metal stents (LAMSs), is a promising intervention for the management of malignant distal biliary obstruction (MDBO). But concerns exist regarding its stent patency. Our aim was to determine whether the insertion of an axis-orienting double-pigtail plastic stent (DPS) through LAMS offered a clinical benefit by improving the stent dysfunction rate.

Distal malignant biliary obstruction (dMBO) is a common complication of advanced malignancies, particularly pancreatic cancer and biliary tract cancer, requiring biliary drainage to relieve symptoms. Endoscopic drainage using self-expandable metal stents (SEMS) is widely preferred due to improved long-term patency compared with plastic stents. However, the choice between fully covered SEMS (FCSEMS) and uncovered SEMS (UCSEMS) remains controversial, primarily due to migration risks associated with FCSEMS.

Background: Pancreatic pseudocyst (PP), following acute or chronic pancreatitis, may become symptomatic or persist beyond 6-8 weeks, requiring drainage. Endoscopic ultrasonography-guided drainage (EUS-D) is the preferred method, using double pigtail plastic stents (DPPS) or self-expandable metallic stents (SEMS), such as lumen-apposing metal stents (LAMS). This meta-analysis compares DPPS and LAMS in EUS-D for PP, focusing on technical success, clinical success, adverse events (AEs), recurrence, and procedure time.
