Distal Bile Duct Metastasis From Rectal Cancer: The Diagnostic Contribution of Intraductal Ultrasonography

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 49‐year‐old male developed liver dysfunction during chemotherapy for rectal cancer located in the rectosigmoid region. Although magnetic resonance cholangiopancreatography initially indicated sclerosing cholangitis, endoscopic retrograde cholangiopancreatography and intraductal ultrasonography revealed multiple non‐contiguous intraductal ...

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.

Troubleshooting of Endoscopic Ultrasound‐guided Rendezvous Using a Nasobiliary Drainage Tube

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided rendezvous (EUS‐RV) is an alternative technique for patients in whom selective bile duct cannulation (SBDC) has failed during endoscopic retrograde cholangiopancreatography (ERCP). However, EUS‐RV has several challenging steps.

Delayed Biliary Hemorrhage due to Pseudoaneurysm Rupture Caused by Migration of Placed Plastic Stent After Endoscopic Ultrasound‐Guided Hepaticogastrostomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an effective method for cases where transpapillary approaches to pancreato‐biliary diseases are challenging, though serious complications often occur. Here, we report an extremely rare case of delayed biliary hemorrhage due to pseudoaneurysm rupture after EUS‐HGS, caused by ...

A Case of Pancreatic Neuroendocrine Tumor Growing Intraductal Extension toward the Main Pancreatic Duct Complicated by Thrombocytopenia: Diagnostic Challenges and Management Strategy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We present a rare and diagnostically challenging case of a pancreatic neuroendocrine tumor (pNET) with intraductal growth into the main pancreatic duct (MPD), complicated by severe thrombocytopenia due to myelodysplastic syndrome. A 37‐year‐old male presented with thrombocytopenia.

Scheduled Inside Plastic Stent Exchange Prevents Cholangitis and Reduces Unplanned Hospitalization in Patients With Unresectable Malignant Hilar Biliary Obstruction

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives To prevent cholangitis in patients with unresectable malignant hilar biliary obstruction (MHBO), we recently implemented scheduled inside plastic stent (IS) exchange every 2–4 months. This study aimed to evaluate whether this strategy prevents cholangitis onset and reduces unplanned hospitalizations without increasing adverse events.

Efficacy of the Stent‐in‐Stent Technique as a Rescue Method for Removing Embedded Metallic Biliary Stents

DEN Open, Volume 6, Issue 1, April 2026.
The stent‐in‐stent technique involves placing another fully covered metal stent inside an irremovable embedded stent to compress tissue and enable safe removal. In this study of 17 patients, the overall technical success rate was 76.5%, with higher efficacy via EUS‐guided hepaticogastrostomy (100%) and transpapillary routes (80%).

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.

A Novel Endoscopic Strategy for Addressing Complex Gastrointestinal Defects via the X‐Tack System: A Case Series With Videos

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT The management of complex gastrointestinal defects (CGDs), such as fistulas, leaks, and anastomotic dehiscence, remains challenging. Over‐the‐scope suturing (OTSS) systems provide effective closure, but their application is limited to specific anatomical sites.
