A Case of Obstructive Jaundice due to Bile Duct Tumor Thrombus of Hepatocellular Carcinoma Diagnosed by Peroral Cholangioscopy

DEN Open, Volume 6, Issue 1, April 2026.
Abstract While hepatocellular carcinoma (HCC) often invades the portal or hepatic vein to form tumor thrombus, tumor thrombus in the bile duct is rare. In such cases, differentiation from intrahepatic cholangiocarcinoma is difficult, and the tumor often appears as a smooth, yellowish‐white, polypoid mass within the bile duct lumen.

Safety Profile of Low‐Power Pure‐Cut Hot Snare Polypectomy for 10–14 mm Nonpedunculated Colorectal Neoplasms

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The reported rate of delayed bleeding (DB) after hot snare polypectomy (HSP) for 10–19‐mm polyps is 2.1%–2.8%, which is non‐negligible. We hypothesized that a low‐power pure‐cut current (LPPC) yields a lower risk of DB than a coagulation current, and we evaluated the safety of LPPC HSP for colorectal polyps.

A Clinical Scoring Model to Predict Post‐Endoscopic Retrograde Cholangiopancreatography Pancreatitis in Biliary Endoscopic Retrograde Cholangiopancreatography for Patients With Intact Papilla: A Large Multicenter Prospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The risk of post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) needs to be predicted in order to take adequate preventive measures in individual cases. The aim of this study was to develop a clinical prediction rule for PEP in biliary ERCP for patients with intact papilla.

Efficacy of Endoscopic Ultrasound‐guided Transluminal Drainage Using Lumen‐apposing Metal Stents for the Treatment of Pancreatic Fluid Collections

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Pancreatic fluid collections (PFCs) are able to develop secondary to either fluid leakage or liquefaction of acute pancreatitis, chronic pancreatitis, pancreatic trauma, or after pancreatic surgery. While most PFCs resolve spontaneously, endoscopic procedures are sometimes necessary.

Preclinical Evaluation of the Safety of the Dedicated Gel for Gel Immersion Endoscopy With Gastrointestinal Perforation and Peritoneal Leakage

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel immersion endoscopic mucosal resection or endoscopic submucosal dissection has been developed as an alternative to saline immersion therapeutic endoscopy. However, in cases of gastrointestinal perforation, gel may leak from the lumen into the peritoneal cavity, and the safety of such events remains unclarified.
