Fluoroscopy-assisted vs fluoroless endoscopic ultrasound-guided transmural drainage of pancreatic fluid collections: A comparative study.

Introduction: The need for fluoroscopy guidance in patients undergoing endoscopic ultrasound-guided transmural drainage (EUS-TMD) of peripancreatic fluid collections (PFCs) remains unclear.

Aims: The aim of this study was to compare general outcomes of EUS-TMD of PFCs under fluoroscopy (F) vs fluoroless (FL).

Methods: This is a comparative study with a retrospective analysis of a prospective and consecutive inclusion database at a tertiary centre, from 2009 to 2015.

EUS-guided methylene blue cholangiopancreatography for benign biliopancreatic diseases after failed ERCP.

Background And Aims: When ERCP fails, EUS-guided interventional techniques may be an alternative. The aim of this study was to evaluate the general outcomes and safety of EUS-guided methylene blue cholangiopancreatography in patients with failed ERCP in benign biliopancreatic diseases.

Methods: Patients with benign biliopancreatic diseases and failed ERCP were included.

Endoscopic necrosectomy of walled-off pancreatic necrosis using a lumen-apposing metal stent and irrigation technique.

Background: Endoscopic management of walled-off pancreatic necrosis (WOPN) is an area of great interest with many still unanswered questions, including the role of mechanical necrosectomy versus irrigation. The aim of this study was to evaluate a new method of endoscopic transmural necrosectomy.

Methods: Patients with WOPN after necrotizing pancreatitis, who underwent endoscopic transmural necrosectomy using a lumen-apposing metal stent with vigorous irrigation sessions, were prospectively recruited between September 2011 and August 2014.
