Novel classification system for walled-off necrosis: a step toward standardized nomenclature and risk-stratification framework
The optimal therapeutic approach for walled-off necrosis (WON) is not fully understood, given the lack of a validated classification system. We propose a novel and robust classification system based on radiologic and clinical factors to standardize the nomenclature, provide a framework to guide comparative effectiveness trials, and inform the optimal WON interventional approach.Visceral artery pseudoaneurysms in necrotizing pancreatitis: risk of early bleeding with lumen-apposing metal stents
Visceral artery pseudoaneurysm (PSA) in necrotizing pancreatitis (NP) is associated with significant morbidity and mortality. This study aimed to evaluate the incidence, clinical presentation, management, and outcomes of PSA in NP.Safety and efficacy of a novel resection system for direct endoscopic necrosectomy of walled-off pancreas necrosis: a prospective, international, multicenter trial
Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN.EUS-directed transenteric ERCP in non–Roux-en-Y gastric bypass surgical anatomy patients (with video)
Enteroscopy-assisted ERCP is challenging in patients with surgically altered upper GI anatomy. This study evaluated a novel procedure, EUS-directed transenteric ERCP (EDEE), in the de novo creation of an enteroenteric anastomosis for the performance of ERCP in non–Roux-en Y gastric bypass (RYGB) patients.Comparison of the effectiveness and safety of lumen-apposing metal stents and anti-migrating tubular self-expandable metal stents for EUS-guided gallbladder drainage in high surgical risk patients with acute cholecystitis
Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using an anti-migrating tubular self-expandable metal stent (ATSEMS) is performed in high surgical risk patients with acute cholecystitis. The newly introduced lumen-apposing metal stent (LAMS) is expected to reduce the risk of tubular self-expandable metal stent–related adverse events such as stent migration, but no comparative studies have been carried out between LAMSs and ATSEMSs for EUS-GBD.
