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 Rare Case of Immune‐related Adverse Events Localized to the Small Intestine

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Enterocolitis is a common gastrointestinal manifestation of immune‐related adverse events (irAEs); however, only a few studies have reported on irAE enteritis with localized active inflammation in the small intestine. Here, we report the case of a 74‐year‐old man who developed diarrhea, abdominal pain, and oral intake difficulty and was ...

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
