Abstract Acute cholecystitis is frequently encountered in daily clinical practice, and early cholecystectomy is the standard therapy. In high‐risk surgical patients, such as those with advanced age, deteriorated performance status, or underlying diseases, conservative treatment is typically preferred to manage acute cholecystitis.

Endoscopic Ultrasound‐guided Drainage With Lumen‐apposing Metal Stent versus Plastic Stent for the Treatment of Pancreatic Pseudocyst: A Systematic Review and Meta‐analysis

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background Pancreatic pseudocyst (PP), following acute or chronic pancreatitis, may become symptomatic or persist beyond 6–8 weeks, requiring drainage. Endoscopic ultrasonography‐guided drainage (EUS‐D) is the preferred method, using double pigtail plastic stents (DPPS) or self‐expandable metallic stents (SEMS), such as lumen‐apposing metal ...

Efficacy and Safety of Multihole Partially Covered Self‐Expandable Metal Stents for Distal Malignant Biliary Obstruction: A Single‐Center Retrospective Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Covered self‐expandable metal stents (SEMS) are the standard for managing unresectable distal malignant biliary obstruction (DMBO), as they prolong the time to recurrent biliary obstruction (TRBO). However, fully covered SEMS (FCSEMS) increases the risk of cholecystitis and pancreatitis.

Active Gallbladder Lavage Using a Double‐pigtail Plastic Stent Delivery System During Endoscopic Ultrasound‐guided Gallbladder Drainage (With Video)

DEN Open, Volume 6, Issue 1, April 2026.
Endoscopic ultrasound‐guided gallbladder drainage using a double‐pigtail plastic stent (DPPS) harbors the risk of bile leakage and pneumoperitoneum through the anastomosis site. When the inner sheath of the DPPS system is retracted halfway back into the stent, multiple side holes emerge on the stent end, which accelerates the active gallbladder lavage.

Clip‐Centered Common Bile Duct Stones Managed by Endoscopic Sphincterotomy Plus Endoscopic Papillary Large Balloon Dilation Years After Cholecystectomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Migration of clips used in laparoscopic cholecystectomy (LC) is rare, but when a clip migrates into the bile duct, it can serve as a nucleus for common bile duct stone formation and trigger acute cholangitis. An elderly woman in her 80s underwent LC for cholecystolithiasis at another hospital in year X.
