A Novel Biliary Plastic Stent With a Centrally Located Flap: Initial Clinical Experience in Three Cases

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Endoscopic biliary plastic stent (PS) insertion is standard for maintaining bile flow, but migration and dislodgement persist as important challenges. We developed the cross range flap stent (CRF stent), a 7 Fr, 7 cm straight‐type PS. Unlike conventional stents with flaps at both ends, the CRF stent features flaps and flap holes at the ...

Balloon Enteroscopy‐assisted Endoscopic Retrograde Cholangiopancreatography for Choledocholithiasis in Situs Inversus Totalis With Billroth II Reconstruction: A Case Report and Literature Review

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) in patients with situs inversus totalis (SIT) and Billroth II reconstruction is technically challenging because of mirror‐image anatomy, altered access to the papilla, and inverted papillary orientation.

Recent Development of Endo‐hepatology

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Endo‐hepatology is a rapidly evolving field encompassing endoscopic diagnosis and treatment of hepatobiliary diseases, primarily using endoscopic ultrasound (EUS). Since its conceptualization in 2012, the field has expanded dramatically alongside advances in interventional EUS. A landmark 2024 review broadened the concept to include endoscopic

Preoperative Diagnosis of the Bile Duct Traumatic Neuroma by Endoscopic Ultrasound‐guided Tissue Acquisition: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Traumatic neuroma of the cystic duct stump is a rare benign lesion that may mimic biliary malignancy, making preoperative diagnosis challenging. We report a case of an enhancing lesion at the cystic duct stump after cholecystectomy that was diagnosed by endoscopic ultrasound‐guided tissue acquisition (EUS‐TA).

Clinical Outcomes of Multi‐Hole Covered Self‐Expandable Metal Stents for Malignant Distal Biliary Obstruction: A Retrospective Comparative Study With an Exploratory Evaluation of 6‐mm Devices

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Covered self‐expandable metal stents (CSEMS) are widely used for malignant distal biliary obstruction (MDBO), but cholecystitis, post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), stent migration, and recurrent biliary obstruction (RBO) remain clinically important limitations.

Efficacy and Safety of Endoscopic Ultrasound‐Guided Biliary Drainage in the Management of Malignant Hilar Biliary Obstruction: A Multicenter Retrospective Cohort Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Malignant hilar biliary obstruction (MHBO) remains challenging for biliary decompression. Although endoscopic ultrasound‐guided biliary drainage (EUS‐BD) has emerged as an alternative to endoscopic retrograde cholangiopancreatography‐guided BD (ERCP‐BD), evidence regarding EUS‐BD for MHBO is limited. Aims To evaluate the efficacy and safety of

Comparative Diagnostic Sensitivity of Endoscopic Ultrasound‐guided Tissue Acquisition for Hepatocellular Carcinoma Versus Intrahepatic Cholangiocarcinoma

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background and Aims Accurate histological differentiation between hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) is essential for selecting appropriate treatment. Endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) is increasingly used for focal liver lesions; however, comparative data on its diagnostic ...

Successful Endoscopic Treatment of Walled‐Off Necrosis With Complex Quadruple Fistulas Among the Necrotic Cavity, Stomach, Duodenum, and Common Bile Duct

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT We report an extremely rare case of duodenal bulb perforation caused by a double‐pigtail plastic stent placed for walled‐off necrosis (WON), coexisting with a biliary fistula to the WON and a choledochoduodenal fistula, all successfully managed with endoscopic treatment alone.

Pediatric Superior Mesenteric Artery Syndrome: A Rare Case Report and Literature Review From Sudan

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT A 10‐year‐old Sudanese boy with chronic bilious vomiting, cachexia, and scaphoid abdomen was diagnosed with Superior Mesenteric Artery Syndrome (SMAS) via CT angiography. After failed conservative management, side‐to‐side duodenojejunostomy resolved symptoms.

Mucosal‐Associated Invariant T Cells in Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
The roles of MAIT cells in health and disease and their therapeutic applications. In healthy individuals, riboflavin metabolites secreted by commensal bacteria at mucosal sites are presented by MR1, leading to the activation of MAIT cells. Activated MAIT cells can maintain the barrier integrity of mucosal tissues in a steady state or migrate to the ...
