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.

Gel Immersion Endoscopic Submucosal Dissection Using a Scissor‐type Knife for Superficial Non‐ampullary Duodenal Epithelial Tumors

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives This study aimed to compare the short‐term therapeutic outcomes between conventional endoscopic submucosal dissection (C‐ESD) and gel immersion ESD (GI‐ESD) for superficial non‐ampullary duodenal epithelial tumors (SNADETs). Methods A retrospective analysis was conducted on patients with SNADETs who underwent C‐ESD or GI‐ESD between

Endoscopic Hemostasis for Gastrointestinal Stromal Tumor Hemorrhage: A Case Series and Retrospective Analysis of Risk Factors

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gastrointestinal stromal tumors (GISTs) are vascular tumors that can cause significant gastrointestinal hemorrhage. While endoscopic treatment is common for other hemorrhagic disorders, its role in GIST‐related hemorrhage remains unclear.

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 ...
