Endoscopic Step‐up Approach for Walled‐off Necrosis After Acute Pancreatitis

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT This review outlines current interventional strategies for treating symptomatic walled‐off necrosis (WON) after necrotizing pancreatitis. Mortality from acute pancreatitis has improved, but late mortality, particularly from infected necrosis, remains a challenge. WON requires invasive treatment in cases of infection or symptoms.

Efficacy and Safety of Remimazolam Compared to Midazolam for Sedation During Endoscopic Ultrasonography: A Single‐Center Retrospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Remimazolam is a novel ultra–short‐acting benzodiazepine that may offer advantages over conventional sedatives in endoscopic procedures. Evidence for its use in pancreatobiliary endoscopic ultrasonography (EUS) is limited. We compared the efficacy and safety of remimazolam and midazolam in outpatient pancreatobiliary EUS.

ABSTRACT Percutaneous biopsy remains the gold standard for diagnosing focal liver lesions; however, endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) has recently emerged as a promising alternative. Although its diagnostic performance is favorable, most available evidence has focused on epithelial tumors, and reports on mesenchymal tumors are ...
