A case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Superficial non‐ampullary duodenal epithelial tumor is a rare disease, but its frequency has reportedly been increasing in recent years. We report a case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa.

Endoscopic findings of gallbladder lesions evaluated with image‐enhanced endoscopy: A preliminary study using resected gallbladders

DEN Open, Volume 6, Issue 1, April 2026.
Abstract The diagnosis of gallbladder (GB) lesions relies on imaging findings. Transpapillary cholangioscopy can potentially be used to diagnose GB lesions; however, the images obtained remain unclear. This study aimed to characterize the endoscopic findings of GB lesions. We examined the endoscopic features of GB lesions in 50 consecutive patients who

Prognostic factors and long‐term outcomes with endoscopic submucosal dissection for colorectal tumors in patients aged 75 years or older

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background Studies regarding the long‐term outcomes of endoscopic submucosal dissection (ESD) performed in older patients with colorectal tumors are limited. Therefore, in this study, we aimed to analyze the long‐term outcomes of older patients with colorectal tumors who underwent ESD and identify prognostic factors.

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.
