Forward‐Viewing Endoscopic Ultrasound‐Guided Fine‐Needle Biopsy for a Hypopharyngeal Carcinoma Mimicking a Subepithelial Lesion: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Subepithelial lesions (SELs) of the head and neck have a low diagnostic yield with mucosal biopsy and carry a bleeding risk. Among endoscopic ultrasound–tissue acquisition (EUS‐TA) techniques, fine‐needle biopsy (FNB) provides higher specimen adequacy and diagnostic accuracy than fine‐needle aspiration (FNA).

Conversion Surgery after Chemotherapy in a Stage IV BRAF V600E‐Mutated Laterally Spreading Tumor With Neuroendocrine Component

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We report a rare case of a BRAF V600E‐mutated laterally spreading tumor, granular type (LST‐G), with a neuroendocrine carcinoma (NEC) component in a patient with stage IV colorectal cancer. The patient presented with multiple lymph nodes and liver metastases.

Clinicopathological Features of Superficial Non‐Ampullary Duodenal Epithelial Tumors Involving Brunner's Glands

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background and Aims Although Brunner's glands (BGs), located in the submucosa of the duodenum, may be involved by tumor cells of superficial non‐ampullary duodenal epithelial tumors (SNADETs), the detailed incidence and histopathological features have not yet been analyzed. This study aimed to clarify the histopathological relationship between

Third‐Generation Narrow‐Band Imaging Versus White‐Light Imaging for the Detection of Early Gastric Cancer: A Randomized Controlled Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The endoscopic system EVIS X1 with improved image quality has been introduced into clinical practice. We examined whether third‐generation narrow‐band imaging (3G‐NBI) is more effective than white‐light imaging (WLI) for detecting early gastric cancer (EGC). Methods Our study, performed at a single center, had a parallel‐group, open‐

Prophylactic Mechanical Closure for Preventing Delayed Bleeding after Gastric Endoscopic Submucosal Dissection: A Systematic Review and Meta‐Analysis

DEN Open, Volume 6, Issue 1, April 2026.
Nine comparative studies (n = 2646) were included. Prophylactic mechanical closure was associated with lower clinically significant delayed bleeding after gastric endoscopic submucosal dissection (risk ratio 0.36, 95% confidence interval 0.16–0.82; I2 = 65%).
