Severe Corrosive Gastritis Caused by Accidental Ingestion of Mildly Alkaline Calcium Chloride Desiccant: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A woman in her 90s with dementia accidentally ingested an unknown amount of calcium chloride–containing desiccant (pH 7–8). Computed tomography (CT) revealed circumferential gastric wall thickening, and upper gastrointestinal endoscopy revealed ulcers with necrotic material extending from the cardia to the greater curvature of the pyloric ...

Additional chemoradiotherapy for superficial esophageal squamous cell carcinoma after near-circumferential or full-circumferential noncurative endoscopic submucosal dissection: a retrospective study

BMC Gastroenterology
Background Endoscopic submucosal dissection (ESD) is a potentially efficient therapeutic intervention for superficial esophageal cancer. Additional treatment such as chemoradiotherapy (CRT) or esophagectomy is recommended in cases of muscularis mucosa ...

Efficacy of the Stent‐in‐Stent Technique as a Rescue Method for Removing Embedded Metallic Biliary Stents

DEN Open, Volume 6, Issue 1, April 2026.
The stent‐in‐stent technique involves placing another fully covered metal stent inside an irremovable embedded stent to compress tissue and enable safe removal. In this study of 17 patients, the overall technical success rate was 76.5%, with higher efficacy via EUS‐guided hepaticogastrostomy (100%) and transpapillary routes (80%).

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.

Congenital Esophageal Muscularis Propria Defect Found during Endoscopic Submucosal Dissection for Early Esophageal Cancer: A Case Report and Management

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Congenital esophageal muscularis propria defects are extremely rare, often complicating endoscopic submucosal dissection (ESD) for esophageal neoplasms. We report a 60‐year‐old man with early esophageal squamous cell carcinoma who underwent ESD.

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).

Enhanced Endoscope is Associated With Success Rates in B2‐ Endoscopic Ultrasound‐Guided Hepaticogastrostomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objective Endoscopic ultrasound (EUS)‐guided hepaticogastrostomy (HGS) in intrahepatic bile duct segment 3 (B3) is widely used for biliary drainage. Post‐puncture procedures are easy to perform in intrahepatic bile duct segment 2 (B2), but using a conventional oblique‐viewing (OV) scope (GF‐UCT260) may result in transesophageal puncture.

Efficacy of Endoscopic Submucosal Dissection for Superficial Esophageal Cancer on the Distal Side of Esophageal Strictures Using a Novel Thin Therapeutic Endoscope

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinomas (ESCCs) localized on the distal side of strictures requires dilation to pass a conventional endoscope. While an ultra‐slim endoscope can pass without dilation, ESD using it remains clinically challenging.

A Case of Refractory Peptic Ulcer with Choledochoduodenal Fistula Successfully Treated by Biliary Stent Placement Using an Ultrathin Endoscopic Rendezvous Technique: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Choledochoduodenal fistula (CDF) is an abnormal communication between the common bile duct and the duodenum. While gallstones are the primary cause, peptic ulcer‐related CDF has become rare due to the widespread antiulcer therapy. Nevertheless, CDF remains clinically relevant as symptoms are often vague and diagnosis is frequently incidental ...

Stricturing Diseases of the Gastrointestinal Tract—Current Clinical Practice

JGH Open, Volume 10, Issue 4, April 2026.
ABSTRACT Gastrointestinal stricture can occur in the esophagus, stomach, small intestine, colon, and anorectum. Most of the strictures are benign. The prevalence of esophageal strictures (ES) secondary to eosinophilic esophagitis has increased. Pyloric stenosis (PS) is rarely seen in clinical practice.
