Barrett's Esophageal Adenocarcinoma with Neuroendocrine Cell Carcinoma Treated by Endoscopic Submucosal Dissection: A Case Report and Literature Review

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Barrett's esophageal adenocarcinoma (BEA) with neuroendocrine cell carcinoma (NEC) is a rare disease with a poor prognosis. We report a case of BEA with NEC treated by endoscopic submucosal dissection (ESD) with en bloc resection and long‐term survival was achieved without additional treatment.

Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three‐dimensional Imaging System

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background and aims Traditional two‐dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software‐based three‐dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes.

Successful Endoscopic Submucosal Dissection for Giant Inflammatory Fibroid Polyp in Terminal Ileum

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 55‐year‐old woman presented with postprandial abdominal pain and diarrhea. Contrast‐enhanced abdominal computed tomography revealed a large tumor in the ileocecal region. Colonoscopy demonstrated a pedunculated polyp originating from the terminal ileum, intermittently prolapsing into the cecum with a stalk‐like base.

Comparison of Transoral Robotic Surgery and Endoscopic Laryngopharyngeal Surgery for Hypopharyngeal and Supraglottic Laryngeal Cancers

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We aimed to compare intraoperative and postoperative outcomes, technical advantages, and limitations of transoral robotic surgery (TORS) using the Da Vinci Xi robotic system and endoscopic laryngopharyngeal surgery (ELPS) for hypopharyngeal and supraglottic laryngeal cancers.

Comprehensive Endoscopic Management of Superficial Pharyngeal Cancer – From Detection and Diagnosis to Treatment and Surveillance

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Traditionally, pharyngeal cancer was detected at an advanced stage, as examinations were usually performed only after symptoms such as pain or dysphagia appeared. Consequently, it was considered a malignancy with a poor prognosis. However, recent advances in image‐enhanced endoscopy (IEE) have facilitated the early detection of superficial ...

A Case of Human Epidermal Growth Factor Receptor 2‐Positive Colon Cancer With Invasive Micropapillary Carcinoma Component

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A female patient in her 60s tested positive for the fecal occult blood test while undergoing health screening. Colonoscopy revealed a 15‐mm‐sized flat elevated lesion with a central depression in the sigmoid colon. Narrow‐band imaging magnification revealed a Japan Narrow‐Band Imaging Expert Team classification of type 2B, whereas crystal ...

Underwater Pressure Lumen Expansion: A Novel Method to Overcome Lumen Collapse in Submucosal Endoscopy and Animal Endoscopic Full‐thickness Resection Models

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT In endoscopic full‐thickness resection (EFTR), luminal collapse can occur due to communication between the gastrointestinal lumen and peritoneal cavity, making visualization and procedural continuity difficult. We propose the underwater pressure lumen expansion (UPLE) method, in which hydraulic pressure is applied in a fluid‐filled environment

Endoscopic Full‐thickness Resection for Gastric Submucosal Tumor: A Technical Analysis Study (With Video)

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Endoscopic full‐thickness resection (EFTR) is an effective treatment method for gastric submucosal tumors (SMTs). We aimed to perform a technical analysis of EFTR in gastric SMT and compare it with the outcome parameters. Method Sixty‐one gastric SMTs from 60 patients were resected using EFTR. The indication criteria: size, 11–30 mm,
