Barrett Esophagus is a common pathology, with an estimated prevalence of 1.6% at risk of progression to precancerous mucosa (low to high grade dysplasia). The incidence of adenocarcinoma on BE is 0.5% per year. In the event of dysplasia or cancer in situ, it is currently recommended at international and particularly European level to eradicate BE. The treatment techniques used to date carry out th...

The investigators hypothesize that careful examination of Barrett's esophagus by high-resolution endoscopy combined with virtual chromoendoscopy could replace the Seattle protocol for Barrett's esophagus monitoring and detection of dysplasic lesions, and thus modify existing recommendations.

We aimed to improve non-invasive screening of varices needing treatment (VNT) and compare different screening strategies. 2,290 patients with chronic liver disease were included in a retrospective study. Etiologies were: virus: 50.0%, NAFLD: 29.5%, alcohol: 20.5%, VNT: 14.9%. Test descriptors were performance (spared endoscopy) and safety (missed VNT). VNT tests were evaluated according to their s...

Therapeutic Advances in Gastroenterology, Volume 15, Issue , January December 2022. Background : Endoscopic papillectomy is a minimally invasive treatment for benign tumors of the ampulla of Vater or early ampullary carcinoma. However, reported recurrence rates are significant and risk factors for recurrence are unclear. Objective : The aims of this study were to evaluate the efficacy and safety...

Therapeutic Advances in Gastroenterology, Volume 15, Issue , January December 2022. Introduction : Patients treated with biologics for inflammatory bowel disease (IBD) have an increased risk of severe infections. Real life vaccination coverage in this population remains low despite international vaccination guidelines. The aim of this study was to evaluate the impact of a dedicated vaccination vi...

Tissue engineering is an attractive alternative to conventional esophageal replacement techniques using intra-abdominal organs which are associated with a substantial morbidity. The objective was to evaluate the feasibility of esophageal replacement by an allogenic decellularized esophagus in a porcine model. Secondary objectives were to evaluate the benefit of decellularized esophagus recellulari...

In Wicked, Incomplete, and Uncertain, Jason Swarts examines the changing role of technical communication in addressing user problems that are becoming more specialized and situated within use cases that users themselves do not readily understand. These emergent and real-time problems have led to the rise of online forums and communities, which this books studies in depth. In particular, Swarts stu...
