About this study
Official title: Lumen Apposing Metal Stents With and Without a Coaxial Double Pigtail Stent in the Management of Pancreatic Fluid Collections
The study evaluates the security of LAMS with ando without a coaxial double pigtail plastic stent in the management of pancreatic fuid collections.
Read the detailed description
The introduction of lumen-apposing metal stents (LAMS) represented a great improvement in the EUS-guided transmural drainage of pancreatic fluid collections (PFCs). It is postulated safer than other types of stents due to the presence of bilateral anchoring flanges, designed to appose the stomach or duodenum to the PFC wall minimizing the risk of perforation or peritoneal leakage. In addition, the larger lumen diameter facilitates the drainage of PFC, specially the walled-off pancreatic necrosis (WOPN). However, secondary adverse effects such as infection due to complete or partial stent obstruction, migration, bleeding or buried LAMS syndrome have also been related . The placement of a coaxial double pigtail plastic within the LAMS has been reported beneficial in order to avoid external migration or the lumen obstruction and to the prevention of bleeding and other adverse events. The aim of this study was to evaluate the efficacy and safety of LAMS with and without a coaxial double pigtail plastic stent in the EUS-guided transmural drainage of PFCs.
