Gel Immersion Endoscopic Submucosal Dissection Using a Scissor‐type Knife for Superficial Non‐ampullary Duodenal Epithelial Tumors

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives This study aimed to compare the short‐term therapeutic outcomes between conventional endoscopic submucosal dissection (C‐ESD) and gel immersion ESD (GI‐ESD) for superficial non‐ampullary duodenal epithelial tumors (SNADETs). Methods A retrospective analysis was conducted on patients with SNADETs who underwent C‐ESD or GI‐ESD between

Efficacy and Safety of Remimazolam Compared to Midazolam for Sedation During Endoscopic Ultrasonography: A Single‐Center Retrospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Remimazolam is a novel ultra–short‐acting benzodiazepine that may offer advantages over conventional sedatives in endoscopic procedures. Evidence for its use in pancreatobiliary endoscopic ultrasonography (EUS) is limited. We compared the efficacy and safety of remimazolam and midazolam in outpatient pancreatobiliary EUS.

Five Cases of Hepatic Mesenchymal Tumors Diagnosed by Endoscopic Ultrasound‐Guided Tissue Acquisition

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Percutaneous biopsy remains the gold standard for diagnosing focal liver lesions; however, endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) has recently emerged as a promising alternative. Although its diagnostic performance is favorable, most available evidence has focused on epithelial tumors, and reports on mesenchymal tumors are ...

Delayed Duodenal Ulcer Perforation Following Esophageal Endoscopic Submucosal Dissection Complicated by Perforation: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Endoscopic submucosal dissection (ESD) is an established treatment of superficial esophageal neoplasms. Common complications include bleeding, perforation, and stricture. However, delayed gastrointestinal perforation distant from the ESD site is exceptionally rare.

Endoscopic Ultrasound‐Guided Fine‐Needle Aspiration for Diagnosing Late‐Stage Pelvic Recurrence of Uterine Leiomyosarcoma 15 Years After Total Hysterectomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasonography (EUS) facilitates high‐resolution visualization of lesions adjacent to the gastrointestinal tract. Uterine leiomyosarcoma (uLMS) is rare, aggressive, and difficult to diagnose. This report describes a rare case of pelvic recurrence of uLMS that occurred 15 years after hysterectomy, which was successfully diagnosed ...

Papillary renal cell carcinoma, formerly known as Type 2: a single institutional study addressing histologic and molecular features

Histopathology, Volume 88, Issue 5, Page 1044-1050, April 2026.
Papillary renal cell carcinoma (pRCC) accounts for 15%–20% of RCC cases and is the second most common histologic subtype of RCC. In contrast to other common RCC subtypes, there continues to be ongoing debate about how to classify RCCs with papillary architecture and eosinophilic cytoplasm, given the heterogeneity of histologic, IHC and molecular ...
