Olmesartan‐induced gastritis with no lower gastrointestinal symptoms: A case report

DEN Open, Volume 6, Issue 1, April 2026.
Abstract A 74‐year‐old man with decreased appetite, weight, and heartburn was referred to our hospital. His medications included olmesartan. Esophagogastroduodenoscopy (EGD) revealed antral‐dominant erosive gastritis and nodular mucosa. A gastric biopsy revealed inflammatory cell infiltration.

“Cat scratch colon” causing cecal perforation as a rare complication due to barotrauma during colonoscopy: A case report and literature review

DEN Open, Volume 6, Issue 1, April 2026.
Abstract “Cat scratch colon” (CSC), characterized by spontaneous bright‐red linear markings or mucosal laceration with bleeding due to air insufflation barotrauma, is a rare complication during colonoscopy. These mucosal lacerations can present as superficial tears that do not generally have clinical repercussions or as deeper tears that damage the ...

A case of hemobilia caused by a pseudoaneurysm resulting in obstructive cholangitis in a patient who underwent plastic stent placement for pancreatic cancer (with video)

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Hemobilia, or hemorrhage within the biliary system, is an uncommon cause of stent obstruction associated with bile duct strictures that are rarely observed with plastic stents. Reports of a pseudoaneurysm as a cause of hemobilia after plastic stent placement are also rare.

Antireflux myoplasty: Endoscopic myoplasty with bilateral sling fiber plication for refractory gastroesophageal reflux disease

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Endoscopic antireflux therapy is a novel endoscopic treatment for refractory gastroesophageal reflux disease. We developed antireflux myoplasty (AR‐MP), a modified version of antireflux mucoplasty (ARM‐P), in which exposed bilateral sling fibers are sutured directly via endoscopic hand‐suturing.

Advancements and limitations of image‐enhanced endoscopy in colorectal lesion diagnosis and treatment selection: A narrative review

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Colorectal cancer (CRC) is a leading cause of cancer‐related mortality, highlighting the need for early detection and accurate lesion characterization. Traditional white‐light imaging has limitations in detecting lesions, particularly those with flat morphology or minimal color contrast with the surrounding mucosa.

Endoscopic Management of Complex Duodenal Ulcer Bleeding Using Over‐the‐Scope Clips: Clinical Insights From a Regional Core Hospital [PDF]

DEN Open
Abstract Objectives Over‐the‐scope clips (OTSCs) are considered an effective endoscopic tool for managing upper gastrointestinal bleeding, including duodenal ulcers, mostly based on data from high‐volume centers with expert endoscopists. This study aimed to evaluate the clinical safety of OTSCs in regional hospital backgrounds and identify the factors ...

Prevention of Adverse Events in Endoscopic Ultrasound‐Guided Biliary Drainage

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided biliary drainage (EUS‐BD) is used when biliary drainage using endoscopic retrograde cholangiopancreatography fails. Recently, it has been adopted as a primary biliary drainage method, and its indications have expanded.
