Volumetric laser endomicroscopy and its application to Barrett's esophagus: results from a 1,000 patient registry. [PDF]

, 2019
Volumetric laser endomicroscopy (VLE) uses optical coherence tomography (OCT) for real-time, microscopic cross-sectional imaging. A US-based multi-center registry was constructed to prospectively collect data on patients undergoing upper endoscopy during

First Successful Regeneration of a Structurally Native‐Like Colon Using a Bioabsorbable Polymer Sheet

Annals of Gastroenterological Surgery, EarlyView.
This study demonstrated that a bioabsorbable polymer sheet (BAPS) can regenerate approximately half the circumference of the colon with native‐like structure and function in an experimental setting. As the model involved immediate closure after perforation and did not reproduce peritonitis, caution is required when considering clinical applicability ...

Mature Tertiary Lymphoid Structures Indicate Good Chemotherapy Response and Prognosis in Advanced Colorectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
In advanced colorectal cancer, tumors with mature tertiary lymphoid structures (TLS) exhibited abundant infiltration of CD3‐ and CD8‐positive lymphocytes in both primary and metastatic sites, indicating an activated immune response. The presence of mature TLS was also associated with favorable chemotherapy sensitivity and improved prognosis.

Endoscopic mucosal resection (EMR) versus endoscopic submucosal dissection (ESD) for resection of large distal non-pedunculated colorectal adenomas (MATILDA-trial): Rationale and design of a multicenter randomized clinical trial [PDF]

, 2016
Background: Endoscopic mucosal resection (EMR) is currently the most used technique for resection of large distal colorectal polyps. However, in large lesions EMR can often only be performed in a piecemeal fashion resulting in relatively low radical (R0)-

A Hypoxia‐Responsive Near‐Infrared Phosphorescence Nanoprobe for High‐Sensitive Detection of Tumor Cells and Imaging of Colorectal Cancer In Situ

Aggregate, EarlyView.
We have successfully developed a hypoxia‐responsive near‐infrared phosphorescent probe, Ir‐PEG. This nanoprobe demonstrates high sensitivity, water solubility, and deep‐tissue penetration. It remains specifically activatable even in the hypoxic intestinal environment, facilitating high‐contrast imaging of orthotopic colon cancer.

Anatomic Diagram as a Novel Assessment Strategy for Subclinical Local Residual Disease in Sinonasal Squamous Cell Carcinoma and Intestinal‐type Adenocarcinoma

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective In the last two decades, transnasal endoscopic surgery (TES) has become pivotal in the management of sinonasal tumors. This approach involves a multiblock tumor resection, adding complexity to the interpretation of surgical margins after pathological examination.
