Clinical Utility and Safety of a Novel Ultraslim Catheter‐Type Peroral Cholangioscope/Pancreatoscope: A Single‐Center Case Series

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Peroral cholangioscopy (POCS) and peroral pancreatoscopy (POPS) enable direct intraductal visualization for pancreatobiliary disease diagnosis and management. Nonetheless, conventional devices have relatively large diameters, limiting their use in narrow ducts.

Pancreatic schwannoma mimicking a mucinous pancreatic neoplasm: a case report

Клинический разбор в общей медицине
Pancreatic schwannoma is an extremely rare benign neurogenic tumor arising from Schwann cells of peripheral nerve sheaths within the pancreas. Preoperative diagnosis remains challenging because of the absence of specific clinical and radiological ...

Survival in Cystic Neoplasms of the Pancreas

Canadian Journal of Gastroenterology, 2009
BACKGROUND: The natural history of pancreatic cystic neoplasms remains poorly understood despite growing evidence on the subject. Pancreatic cysts display a wide spectrum of pathological phenotypes, each associated with a different prognostic implication.

Transpapillary Placement of a Multihole Covered Metal Stent Using a 5.9‐Fr Delivery System Through a Forward‐viewing Endoscope in Malignant Biliary Obstruction With Type I Duodenal Stenosis

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Concurrent malignant biliary obstruction (MBO) and type I duodenal stenosis represent a technically demanding scenario, as luminal narrowing frequently precludes passage of a standard side‐viewing duodenoscope and limits conventional transpapillary drainage.

Comparison of Two Partially Covered Metal Stents for Endoscopic Ultrasound‐guided Hepaticogastrostomy: A Multi‐Center Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an alternative biliary drainage method after failed endoscopic retrograde cholangiopancreatography. Nevertheless, it is associated with adverse events (AEs), including peritonitis and stent migration.

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.

An Anatomist's View on the Crosstalk Between the Liver and the Lung

Comprehensive Physiology, Volume 16, Issue 6, December 2026.
The liver and the lung have a similar three‐dimensional and cellular architecture as well as functional communalities. The structural, functional, and pathophysiological interplay between both organs suggests the existence of an interorgan axis, the liver‐lung axis. Created in biorender.com.

Dynamic control of carbon‐ion radiation dose distribution amid respiratory motion challenges: A review of prediction research using geant4 and deep learning physics‐constrained models

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Carbon ion radiotherapy (CIRT) offers superior dose conformity and biological effectiveness; however, its precision is highly sensitive to respiratory motion, leading to dose uncertainty and interplay effects that compromise treatment accuracy.
