Successful Endoscopic Excision for a Rapidly Enlarging Esophageal Histopathologically Unclassified Subepithelial Lesion: A Case Report

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 75‐year‐old man presented with an esophageal subepithelial lesion (SEL) measuring 2.5 cm, first identified over a decade ago. The patient was followed up regularly with computed tomography and endoscopy and remained asymptomatic since then. However, over the past year, the patient developed dysphagia, and endoscopic evaluation revealed that ...

Gel‐immersion Endoscopic Submucosal Dissection for Superficial Colorectal Neoplasms: A Retrospective Study Comparing Conventional Endoscopic Submucosal Dissection

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel‐immersion endoscopy offers benefits such as buoyancy, traction, and a clear visual field without gas insufflation. While some case reports have described colorectal gel‐immersion endoscopic submucosal dissection (Gi‐ESD), there have been no consecutive case series. This study aimed to clarify the usefulness of Gi‐ESD.

Diagnostic Performance of Magnifying Endoscopy With Crystal Violet Staining for Superficial Non‐ampullary Duodenal Epithelial Tumors: A Single‐center Prospective Study

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We previously reported a potential diagnostic algorithm for superficial non‐ampullary duodenal epithelial tumors (SNADETs) using white‐light magnifying endoscopy with crystal violet staining (ME‐CV). This study aimed to determine the diagnostic performance of the scheme and compare it with the conventional white‐light endoscopy (WLE)

Underwater Endoscopic Mucosal Resection as a Salvage Strategy for a Non‐Lifting Early Sigmoid Colon Carcinoma After Failed Conventional Endoscopic Mucosal Resection: A Case Report

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic mucosal resection (EMR) has been widely adopted as an endoscopic treatment for colorectal tumors. However, in non‐lifting lesions, EMR often becomes technically challenging, leading to piecemeal resection or residual tumor. Recently, underwater EMR (UEMR) has been developed as a novel technique that allows mucosal and submucosal ...

Polyglycolic Acid Sheet Application to Refractory Delayed Bleeding After Rectal Endoscopic Submucosal Dissection: A Case Report

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A man in his 50s underwent endoscopic submucosal dissection (ESD) for a rectal tumor measuring 28 mm. He was not taking any antithrombotic medication. On the third, 11th, 18th, and 24th days after the procedure, bleeding was observed from different areas of the ulcer bed margin and was managed with hemostatic forceps.
