Active clinical trials for "Esophageal Diseases"

In this study,the investigators will evaluate participants that have clinical features associated with an increased risk of esophageal disorders.The investigators will also see if there is a positive association of esophageal disorders in men,40-60 with or without abdominal obesity in the diagnosis of the following diseases; Gastroesophageal reflux disease, Barrett Esophagus and Esophageal Adenocarcinoma. The investigators hypothesize that most obese patients referred for Esophagogastroduodenoscopy will exhibit esophageal disorders. Since currently the rates of obesity and adenocarcinoma of the esophagus have increased significantly over the past 15 years, the investigators hope to find biochemical markers (i.e. pro-inflammatory mediators) in the esophagus. The investigators hope these samples will lead us to a differential expression of molecular markers and inflammatory mediators in the varying degrees of esophageal disorder

The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach.). The two methods of sampling are: 1) Using forceps that take biopsies (small tissue samples) from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus. By recording the results of all of your biopsies over many years, it may be possible to find out if the brush biopsy, forceps biopsy, or both can predict which patients with heartburn develop Barrett's esophagus, (an abnormality in the esophagus that may lead to cancer), and which patients with Barrett's esophagus develop precancer and cancer. The data from your biopsies will be used to determine the best way to diagnose esophageal disease. You are being asked to participate in the study because you are receiving an upper endoscopy (a procedure where a tube with a light and camera are inserted in your mouth and down your throat) with forceps and brush biopsies of your esophagus as part of your standard clinical care, and you are between the ages of 18 and 80.

Our main objective is to evaluate the effect of Ocoxin-Viusid on the quality of life of patients with advanced stomach cancer and esophagogastric junction. The Ocoxin-Viusid nutritional supplement is expected to improve quality of life and tolerance to treatment with Chemotherapy.

The aim of this pilot study is to assess the feasibility and safety of the clinical application of ultrasound capsule endoscopy in esophageal examination compared with conventional endoscopic ultrasound examination.

Upper Gastrointestinal Submucosal Tumors are tumors arising from subepithelial layers of esophageal, gastric or duodenal wall. They usually have an intact mucosa lining on the inner surface. The prognosis and treatment of these tumors depend on their correct diagnostics and mitotic activity in case of Gastrointestinal Stromal Tumors (GIST). A standard forceps biopsy of mucosa is usually not helpful. Therefore, biopsy techniques capable of reaching deeper layer of Upper GUT are needed. The investigators compare KHB and EUS-FNA in the diagnostics of Upper gastrointestinal Submucosal Tumors.

assess the incidence of the entire spectrum of esophageal disorders and possible theories for overlap in IBS patients using different diagnostic modalities.

The purpose of this study is to better understand how esophageal cells change with age.

Background Esophageal carcinoma is the sixth leading cause of cancer -related mortality and the eighth most common cancer worldwide The incidence is increasing rapidly The overall 5-year survival ranges from 15% to 25% in the literature and poor outcomes are related to diagnosis at advanced stages. Surgery used to be the cornerstone of treatment of resectable esophageal cancer, but treatment of esophageal carcinoma remains challenging and need to be considered through a multimodal approach. However the modalities and the impact of this multimodal approach at a national level are unknown Primary objective: To identify predictors of recurrence after esophageal cancer surgery Secondary objectives : 5-year recurrence free survival 5-year overall survival Predictors of postoperative mortality and morbidity after surgery Impact of pCR on recurrence and survival Impact of neoadjuvant treatments on recurrence and survival Impact of patient preconditioning (such as nutritional support, esophageal prosthesis, mini-invasive approach…) on outcomes Methodology : European French-speaking retrospective multicentric study Inclusion criteria: All consecutive patients operated on, for a histologically proven carcinoma of the esophagus, the oesophago-gastric junction (Siewert type I and II), in surgical investigator centers between January 2000 and December 2010 Exclusion criteria: Siewert III type carcinoma of the oesophago-gastric junction , non surgical treatment of esophageal carcinoma Planned study period: The data will be collected over a 11-year period from January 2000 to December 2010. Follow up will be ascertained in May 2013.

Patients scheduled to undergo routine upper endoscopy for foregut or esophageal symptoms or undergoing surveillance for Barrett's esophagus with no dysplasia or low-grade dysplasia are candidates for participation, but patients with known high-grade dysplasia or adenocarcinoma or with a history of prior endoscopic resection or ablation for these conditions are not candidates for participation. At endoscopy, all patients will be initially assessed for the presence of an endoscopic suspicious lesion using white light and if appropriate narrow band imaging or similar enhanced imaging techniques. All suspicious lesions undergo targeted biopsy first, and then either 4-Quadrant Random Forceps Biopsy or WATS biopsies of the GEJ and if present the columnar-lined esophagus based on the assigned randomization away from the area of targeted biopsies. A biopsy will be obtained from the antrum in each patient to assess for H. pylori infection and the presence of intestinal metaplasia.

The recently developed endoscopic Confocal probe microscopy system allows imaging of surface epithelium during ongoing endoscopy (upper and lower) with the potential of immediate diagnosis of various GI pre-malignant and malignant lesions. The purpose of this study is to determine if using this new Confocal probe system can find pre-cancerous abnormalities in the stomach and colon. Hypothesis: The confocal endomicroscopy images of colorectal lesions during the standard colonoscopies could help the classification in vivo of colorectal neoplastic and non-neoplastic lesions. This could direct further endoscopic interventions such as targeted biopsies of early colorectal cancer lesions and the endoscopic resection of such lesions during screening colonoscopies. Primary Aim To determine the key confocal image features of neoplastic and pre-neoplastic colorectal lesions including flat and raised adenomatous polyps, intraepithelial neoplasia and cancer as well as benign lesions such as hyperplastic polyps and normal colonic epithelium and to estimate which morphologic features best distinguish neoplastic and non-neoplastic tissues. Secondary Aims: To determine the initial sensitivity and specificity of confocal microendoscopy imaging for classification of adenomatous from hyperplastic polyps of the colon. In this exploratory phase of the study to develop a library of confocal microendoscopic imaging characteristics of other GI pathologies such as: Barrett's esophagus in comparison to Barrett's esophagus with dysplasia, and normal squamous esophagus. Other encountered inflammatory and neoplastic conditions within the GI tract in which biopsy or removal of tissue would routinely be indicated. The second phase of the study will focus on establishing the sensitivities, specificities, accuracy of confocal images of colorectal lesions and other GI pathologies as well as inter-observer agreement and learning curve in interpretation of confocal images.
