A case of hemobilia caused by a pseudoaneurysm resulting in obstructive cholangitis in a patient who underwent plastic stent placement for pancreatic cancer (with video)

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Hemobilia, or hemorrhage within the biliary system, is an uncommon cause of stent obstruction associated with bile duct strictures that are rarely observed with plastic stents. Reports of a pseudoaneurysm as a cause of hemobilia after plastic stent placement are also rare.

Endoscopic features of deficient mismatch repair/microsatellite instability‐high and BRAF‐mutated colorectal cancer

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objective Recent advancements in genome analyses, including the BRAF gene and mismatch repair (MMR) gene/microsatellite instability (MSI), have revealed the biological diversity of colorectal cancer (CRC). BRAF‐mutated CRC has a poor prognosis; however, cases exhibiting deficient MMR (dMMR)/MSI‐high (MSI‐H) and BRAF gene mutations have ...

Endoscopic Management of Complex Duodenal Ulcer Bleeding Using Over‐the‐Scope Clips: Clinical Insights From a Regional Core Hospital

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Over‐the‐scope clips (OTSCs) are considered an effective endoscopic tool for managing upper gastrointestinal bleeding, including duodenal ulcers, mostly based on data from high‐volume centers with expert endoscopists. This study aimed to evaluate the clinical safety of OTSCs in regional hospital backgrounds and identify the factors ...

Endoscopic Retrograde Cholangiopancreatography‐guided Biliary Drainage with Duckbill‐type Anti‐reflux Metal Stent versus Endoscopic Ultrasound‐guided Hepaticogastrostomy for Malignant Distal Biliary Obstruction in Pancreatic Cancer with Duodenal Invasion

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Duodenal invasion is a risk factor for early recurrent biliary obstruction (RBO) due to the increased risk of duodenobiliary reflux. Transpapillary biliary drainage using anti‐reflux metal stents (ARMS) and endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) are two different strategies for this condition.

Pancreatic Neuroendocrine Tumor Leading to a Diagnosis of Multiple Endocrine Neoplasia Type 1

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Pancreatic neuroendocrine neoplasms are rare but occasionally encountered. They are generally highly vascularized solid tumors, often round in shape with clear boundaries, defined contours, and a homogeneous internal structure. However, they can also present with atypical features, such as cystic degeneration, hemorrhage, calcification, and ...
