Filter by:A multicenter, prospective, single arm, non randomized clinical trial to evaluate the safety and efficacy of the C2 CryoBalloon Focal Ablation System (CbFAS) for the treatment of persistent dysplasia or intestinal metaplasia (IM) in the tubular esophagus after 3 or more radiofrequency ablations (RFA) for dysplastic BE, or <50% eradication of Barrett's Esophagus (BE) after 2 RFA treatments.
Inlet patch is a congenital condition of the upper oesophagus, consisting of stomach lining that is in the wrong place. It affects 5% of the population. Symptoms are a feeling of a ball in the back of the throat (called chronic globus sensation), cough and sore throat - these account for 4% of general practitioner (GP) referral to Ear Nose & Throat departments. There is no recognised treatment. Drugs that reduce acid may help but do not block mucus production. Argon Plasma coagulation has been shown to be successful but limited to a few expert centres. The investigators have previously shown a device that uses radiofrequency energy to remove the patch to be highly effective in a ten patient pilot study, with 80% response rate that was durable over 1 year. The purpose of this trial is to demonstrate the previous study was not due to placebo effect alone, with a sham controlled arm. Patients would then crossover to treatment at 6 months after sham. All males and non-pregnant females over 18 years old with previously diagnosed inlet patch causing symptoms of globus, with > 50% severity on a visual analogue score, are eligible.
The study will compare EMR versus ESD technique (both combined with subsequent ablative therapy) of mucosal resection in Barrett's esophagus with regard to efficacy and risk in a long term setting.
The purpose of this study is to evaluate the efficacy and safety of the new technique of HybridAPC in the treatment of Barrett.
The aim of the clinical trial is to evaluate the EndoRotor®'s ability to completely remove areas of Barrett's esophagus considered refractory after 3 failed ablation treatments (Radiofrequency Ablation (RFA) and/or Cryotherapy) or in patients with at least 1 failed ablative procedure (RFA and/or Cryotherapy) and are intolerant to the procedure due to pain, where intolerant is defined as post-dysphagia or odynophagia persisting for 24 hours or greater or requiring narcotic analgesia for a duration of more than 24 hours.
The purpose of this Phase II, Open-label, single arm, exploratory study is to evaluate the efficacy and the safety of Apatinib(500mg/d)for the second - line treatment of esophageal cancer or esophageal and gastric
Barrett's oesophagus is a transformation of the esophageal mucous membrane there intestinal metaplasia under the effect of gastro- esophageal reflux disease (GERD). This metaplasia can evolve in low grade dysplasia LGD) , high grade dysplasia (HGD) then invasive adenocarcinoma. The treatment of the HGD of the Barrett is the endoscopic treatment. It is about a superficial treatment of tumor without ganglionar invasion by definition. The endoscopic treatment of the Barrett began in the 2000s, and showed its long-term efficiency. The studied factors of recurrences are the length of the Barrett, the influence of the eradication completes of the Barrett besides the eradication of the dysplasia, as well as the duration of spacing of the procedures. An anatomical zone is particularly delicate to treat. It is about the anatomical junction between the oesophagus and the stomach appointed junction oeso-gastric or cardia or line Z. This almost virtual zone is the site of most of the recurrence. The first cause of the oesophagus of Barrett and of its transformation in HGD is the reflux. This reflux can be handled by medicinal action inhibitor of the pump with proton (PPI) or by surgery (hemi-fundo plicator). This reflux is probably the cause of the long-term recurrence found in the literature. The surgery is a good treatment of the reflux with however unsatisfactory long-term results. On the other hand, the surgery is little used after endoscopic treatment of a HGD not to compromise the surveillance and the detection of a second offense potentially masked in the surgical fundo-plicator. The endoscopic treatment of the expensive ebb because of the based necessary material too on a fundo-plicator is complicated with use in reason also of his cost. The medical treatment by PPI for life, besides his duration and thus the potential hardness for the patient, presents long-term complications recently described. Effects on the appearance of gastric precancerous lesion is not certain, but this association with an osteoporosis is more proved true. The PPI could also be a etiologic factor of chronic renal insufficiency and insanity. An endoscopic treatment describes by Inoue " Anti-Reflux Mucosectomy " ( ARMS) allows to decrease the gastro- esophageal reflux disease. This treatment is an equivalent of on treatment of the line Z which would at the same time allow to make sure of the decrease of recurrence on the line Z by complete treatment of this one and to handle the reflux of these patients. In this experimental series, 10 patients having made this endoscopic treatment were able to stop their treatment by PPI. The purpose of this study will be to make sure of the efficiency of the endoscopic treatment of the reflux by it on treatment of this line Z while decreasing the frequent recurrences on this line Z.
Confocal Endomicroscopy for Permeability of Esophageal Wall in Refractory Gastroesophageal Reflux Disease (GERD)
Aim of this prospective multicenter study is to evaluate the safety of an endoscopic follow-up strategy in patients treated with endoscopic resection (ER) for submucosal or high-risk mucosal esophageal adenocarcinoma (T1bN0M0 or HR T1aN0M0 EAC).
This study will examine the hypothesis that altered esophageal microbiome leads to the development of esophageal adenocarcinoma (EAC). The aims of the project are, firstly the confirmation of relational data on the study cohort, using the methods developed and applied at the laboratory at University of Queensland Diamantina Institute (UQDI). Second, to generate a tissue microarray resource future tissue in-situ validation of microbes. And finally, to develop a biobank of clinical isolates of relevant esophageal microbes for future functional studies.
