Management of small subepithelial tumors by endoscopic banding without resection and single-incision needle-knife-assisted biopsy sampling: a prospective multicenter study.

Background And Aims: Endoscopic band ligation (EBL) without resection combined with single-incision needle-knife (SINK) biopsy sampling may have a positive impact on small GI subepithelial tumor (SET) management, but the method needs to be tested. The aim was to evaluate the feasibility of this strategy in small-sized SETs.

Methods: This prospective multicenter observational cohort study in 7 centers included patients with SETs ≤15 mm (confirmed by EUS) between March 2017 and March 2020.

Endoscopic biliary drainage in unresectable biliary obstruction: the role of endoscopic ultrasound-guidance in a cohort study.

Background And Study Aims: the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) has increased in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) and there are some concerns. The main aim of the study was to determine the role of EUS-BD in a palliative case cohort. The secondary aim was to compare the efficacy, safety and survival of EUS-BD and ERCP procedures.

A novel rescue maneuver for a distal dislodged lumen-apposing metal stent (LAMS): "LAMS-in-LAMS" technique.

Introduction: the appearance of the lumen-apposing metal stent (LAMS) has meant an authentic revolution. To date, the results are promising but it is necessary to note the technical incidents and LAMS-related complications.

Case Report: an EUS-transmural guided drainage using a HotAXIOS was planned for a 36-year-old man with oral intolerance due to a voluminous walled-off necrosis.

Safety of lumen-apposing stent with or without coaxial plastic stent for endoscopic ultrasound-guided drainage of pancreatic fluid collections: a retrospective study.

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.

EUS-guided ethanol ablation therapy for gastric stromal tumors.

EUS-guided fine-needle ethanol injection (FNI) therapy of some types of cystic and solid tumors has been documented. However, reported cases to date of gastrointestinal-stromal tumors (GIST) treated with this technique are scarce. Ethanol ablation is an alternative treatment with a low rate of adverse events in selected cases.

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 recanalization of complete gastrointestinal strictures.

Background And Aim: Complete gastrointestinal strictures are a technically demanding problem. In this setting, an anterograde technique is associated with a high risk of complications and a combined anterograde-retrograde technique requires a prior ostomy. Our aim was to assess the outcome of a first case series for the management of complete gastrointestinal strictures using endoscopic ultrasound (EUS)-guided puncture as a novel endoscopic approach.

Visceral leishmaniasis with mediastinal lymphadenopathy diagnosed with endoscopic ultrasound-guided fine needle aspiration.

A 44-year-old man with a HIV infection and levels of CD4 < 100/mm3, under antiretroviral therapy and with a previous medical history of visceral leishmaniasis (VL), was admitted to hospital with progressive muscular weakness and paraesthesia in both legs for three months. Imaging procedures were performed, showing a leptomeningeal thickening and enlargement of hilar and mediastinal lymph nodes.

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.
