Prospective assessment of probe‐based confocal laser endomicroscopy under direct cholangioscopic visualization for biliary strictures that could not be definitively diagnosed using endoscopic retrograde cholangiopancreatography (with video)

DEN Open, Volume 5, Issue 1, April 2025.
Abstract The definitive diagnosis of patients with indeterminate biliary strictures remains challenging. Probe‐based confocal laser endomicroscopy (pCLE) provides real‐time histological assessment of bile duct tissues. Since no previous studies have evaluated the efficacy of pCLE under direct cholangioscopic visualization for biliary strictures that ...

Efficacy and safety of a novel polytetrafluoroethylene‐coated self‐expandable metal stent for distal malignant biliary obstruction

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Background Stent migration and sludge formation remain significant problems associated with covered self‐expandable metal stents (CSEMSs). The EGIS biliary stent fully covered flare type (EGIS biliary stent), a new type of polytetrafluoroethylene‐coated self‐expandable metal stent with low axial force and an anti‐migration system, was ...

Chained Flexible Capsule Endoscope: Unraveling the Conundrum of Size Limitations and Functional Integration for Gastrointestinal Transitivity [PDF]

arXiv
Capsule endoscopes, predominantly serving diagnostic functions, provide lucid internal imagery but are devoid of surgical or therapeutic capabilities. Consequently, despite lesion detection, physicians frequently resort to traditional endoscopic or open surgical procedures for treatment, resulting in more complex, potentially risky interventions.

Outcomes of multi‐hole self‐expandable metal stents versus fully covered self‐expandable metal stents for malignant distal biliary obstruction in unresectable pancreatic cancer

DEN Open, Volume 5, Issue 1, April 2025.
Abstract Objectives The multi‐hole self‐expandable metal stent (MHSEMS) is a novel SEMS with multiple small side holes on the covering membrane to prevent stent migration while minimizing tumor ingrowth. This study aimed to evaluate the clinical outcomes of MHSEMS in comparison with conventional covered SEMS (c‐CMS).

EndoDepth: A Benchmark for Assessing Robustness in Endoscopic Depth Prediction [PDF]

arXiv
Accurate depth estimation in endoscopy is vital for successfully implementing computer vision pipelines for various medical procedures and CAD tools. In this paper, we present the EndoDepth benchmark, an evaluation framework designed to assess the robustness of monocular depth prediction models in endoscopic scenarios.
