The role of fiberoptic endoscopy in the diagnosis and management of duodenal neoplasms

The American Journal of Digestive Diseases, 1975
This is a study of 11 cases of duodenal tumors encountered in 1200 consecutive duodenoscopic examinations over a 34-month period at The Johns Hopkins Hospital. Of these tumors, 4 were benign and 7 malignant. Endoscopic removal of 2 benign tumors was accomplished without morbidity and obviated the necessity for transabdominal surgery. The 2 other benign

Differentiation between duodenal neoplasms and non‐neoplasms using magnifying narrow‐band imaging – Do we still need biopsies for duodenal lesions?

Digestive Endoscopy, 2020
Endoscopic biopsies for nonampullary duodenal epithelial neoplasms (NADENs) can induce submucosal fibrosis, making endoscopic resection difficult. However, no biopsy‐free method exists to distinguish between NADENs and non‐neoplasms.

Feasibility of laparoscopic endoscopic cooperative surgery for non‐ampullary superficial duodenal neoplasms: Single‐arm confirmatory trial

Digestive Endoscopy, 2020
Laparoscopic endoscopic cooperative surgery for duodenal tumors (D‐LECS) has been developed to prevent duodenal leakage by reinforcing the endoscopic submucosal dissection site.

ENDOSCOPIC CLASSIFICATION OF NEOPLASMS OF THE MAJOR DUODENAL PAPILLA

Oncology bulletin of the Volga region, 2022
. Adenomas of the Vater papilla are benign neoplasms, but due to the tendency to malignancy in 30-40% of cases they should be removed. Methods of removing tumors of the Vater papilla are pancreatoduodenal resection, transduodenal papillectomy and ...

Duodenal neoplasms of gastric phenotype: reports of two cases and a brief review of literature.

European Journal of Cancer Prevention, 2020
Duodenal neoplasms of gastric phenotype are uncommon epithelial neoplasms. Pyloric gland adenomas should be recognized as neoplasms with risk for transformation into invasive adenocarcinoma (Choi et al. 2018).

A case of neuroendocrine neoplasm of the minor duodenal papilla

Clinical Journal of Gastroenterology, 2022
A 61-year-old woman was referred to our hospital for intraductal papillary mucinous neoplasm with no symptoms. Magnetic resonance imaging (MRI) depicted a 15 mm nodular lesion at the descending portion of duodenum. Upper gastrointestinal endoscopy showed a submucosal tumor-like mass at the minor duodenal papilla. A boring biopsy of the tumor revealed a

Endoscopic mucosal resection under gel immersion for superficial nonampullary duodenal epithelial neoplasms

Endoscopy, 2021
Underwater endoscopic mucosal resection (UEMR) has been recently reported to be effective against superficial nonampullary duodenal epithelial neoplasms (SNADENs) [1]. Superficial lesions float up as protruding lesions under water.

Duodenal neuroendocrine neoplasms with unexpectedly aggressive behaviour: Challenging the “watch and wait” approach

Journal of neuroendocrinology, 2021
The incidence of duodenal neuroendocrine neoplasms has risen over the past decades as a result of the wide availability of endoscopy and associated expertise.
