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.

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]

, 2017
We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

Pancreatitis Following Biliary Endoscopic Retrograde Cholangiopancreatography for Common Bile Duct Stones in Japan: A Multicenter Prospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is an adverse event of ERCP‐related procedures. The present study aimed to evaluate the incidence of PEP in patients with an intact papilla who underwent ERCP for common bile duct stones and identify risk factors and preventive measures for PEP.
