Active clinical trials for "Esophageal Diseases"

Open, prospective, one-arm feasibility and efficacy study of a European conformity (CE) certified Combination product of two CE certified medical devices in the intended indication. Evaluation of the suitability of the medical device for sealing leaks in the gastrointestinal tract

The objective of this study is to evaluate the efficacy and safety of concurrent chemoradiotherapy combined with Itraconazole in patients with locally adcvanced esophageal squamous cancer

Immunotherapy is now considered to be one of promising approaches for treating cancer. Radiation therapy has been to be a cornerstone treatment for unresectable advanced esophageal cancer. Radiation-induced mutation genes were identified as new sources of tumor associated antigens using exon sequencing and peptide microarray technologies. Epitope peptides for these targets are able to induce peptide specific cytotoxic T lymphocytes (CTL). In this clinical trial, investigators evaluate the efficacy and safety of peptide specific CTL therapy in combination with radiation therapy in treating patients with unresectable, advanced or recurrent esophageal cancer.

This study evaluates the efficacy and safety of the Per-Oral Endoscopic Myotomy (POEM) technique for lower esophageal sphincter myotomy in patients suffering from spastic esophageal disorders such as achalasia at a Canadian institution. The investigators hypothesize that POEM is a safe and effective technique for the surgical management of such disorders at our institution.

Corrosive substance ingestion in childhood is a public health issue in developing countries and several management protocols were proposed to prevent esophageal strictures. The role of corticosteroids in preventing corrosive-induced strictures is controversial. The investigators' aim is to study the influence of high doses of corticosteroids to prevent esophageal strictures.

A Tanzanian pilot study to test the feasibility of using the Cytosponge™ device - a less-invasive endoscopy alternative - for research on esophageal squamous cell carcinoma in African settings.

No recommendation regarding antibiotic prophylaxis and preparation modalities are available for patients with esophageal motor disorders who benefit from Per-Oral Endoscopic Myotomy (POEM). The aim of our study was to evaluate the impact of antibiotic prophylaxis on the POEM's safety. This study was a comparative and multicentric retrospective analysis of a database prospectively maintained. Patients over 18 year's old with esophageal motor disorders confirmed by prior manometry, who underwent POEM were included. The primary endpoint was the occurrence of complications, as classified by Cotton, based on whether or not antibiotic prophylaxis was administered.

This is a pilot study of a novel disposable transnasal esophagoscope for feasibility, safety and tolerance.

Catheter ablation is an established treatment for atrial fibrillation (AF). For those with the more longstanding form of the condition and are graded as longstanding persistent AF, catheter ablation techniques often involve an extensive ablative protocol. This often includes application of ablation energy to the posterior left atrial wall. The left atrial (LA) wall is only on average 5 millimetres away from the esophageal wall. It has been shown that ablation to the posterior LA wall can cause thermal injury to the esophageal wall. Even those that require pulmonary vein isolation only can be at risk of esophageal injury. This injury can impact on patient symptoms as well as increase the risk of an atrio-esophageal fistula being formed. Esophageal protection methods during catheter ablation for AF in current practice is very limited and investigation towards improved approaches, in the form of a randomized clinical trial is required. The aim or purpose of this research project is to study the effect of esophageal cooling on the incidence of esophageal thermal injury (endoscopy-graded esophageal epithelial lesions and/or the presence of ablation-related gastroparesis with patient symptoms) compared to controls, after a catheter ablation procedure for the treatment of AF.

The capacity for endoscopical procedures in the Norwegian health system is low in comparison to demands from patients and family practitioners. The studies aim is to evaluate the acceptance of a new concept: an open access gastroscopy clinic where patients can attend without a preceding appointment. The investigators wish to evaluate: Patient´s satisfaction. General practitioner´s satisfaction. Acceptance by the staff of the clinic.
