Radiofrequency ablation (RFA) has become the recommended endoscopic treatment for flat dysplastic Barrett's esophagus. However, the outcomes of this treatment are variable across European countries. Our aim was to report the results of a French high-volume center, and to investigate factors associated with treatment failure. We conducted a single-center retrospective study from a prospectively col...

Endoscopic mucosal resection (EMR) is the recommended treatment for superficial non-ampullary duodenal epithelial tumors larger than 6 mm. This endoscopic technique carries a high risk of adverse events. Our aim was to identify the risk factors for adverse events following EMR for non-ampullary duodenal adenomatous lesions. We retrospectively analyzed a prospectively collected database of consecut...

Pancreatic neuroendocrine tumors (p-NETs) are rare tumors with a recent growing incidence. In the 2017 WHO classification, p-NETs are classified into well-differentiated (id est, p-NETs grade 1 to 3) and poorly differentiated neuroendocrine carcinomas (id est, p-NECs). P-NETs G1 and G2 are often non-functioning tumors, of which the prognosis depends on the metastatic status. In the localized setti...

Gastric linitis plastica (GLP) is a diffuse infiltrating type of gastric adenocarcinoma. It is associated with a poor prognosis and a five-year survival of 3-10%. The infiltrating profile of this tumor explains the low yield of the superficial mucosal biospies. The objective of this study was to investigate the role of endoscopic ultrasound-fine needle biopsy (EUS-FNB) in the diagnosis of GLP. We ...
