Does Laparoscopic Sleeve Gastrectomy Lead to Barrett's Esophagus, 5-year Esophagogastroduodenoscopy...

Barrett Esophagus

Introduction Laparoscopic Sleeve Gastrectomy (LSG) is one of the most prevalent approaches to tackle obesity and its co-morbidities. The main complication following the LSG is Gastro-esophageal reflux disease (GERD), with most patients developing worsening symptoms of GERD, and a small number progressing to Barrett's esophagus. This retrospective analysis aims to assess the rate of GERD pre- and post- LSG as well as the rate of progression to Barrett's. Methods Data was collected from 1639 patients. 92 patients fit our inclusion criteria. Data was then analyzed and summarized against similar literature

Effect of Zinc on Barrett's Metaplasia

Barrett's Metaplasia

Using orally administered zinc to patients already diagnosed with the pre-cancerous condition, Barrett's Esophagus, this study is asking two questions: can this zinc administration cause molecular-level changes in the Barrett's tissue? are the changes measured indicative of chemopreventive action by zinc regarding cancer progression?

The Role of the Fujinon Intelligent Chromo Endoscopy (FICE™) in Barrett's Esophagus

Barrett's Esophagus

The purpose of this study to assess post ablation, if there are areas of Barrett's mucosa post ablation and to assess the ability of the Fujinon FICE system to detect this, as compared to white light endoscopy. A subgroup will also be compared with laser confocal microscopy

Micro-RNA (miR) Expression in Upper Gastrointestinal Mucosal Tissue

Barrett's EsophagusEsophageal Adenocarcinoma

This is a laboratory-based, exploratory study using tissue obtained from our clinical practice. The purpose of this study is to confirm our ability to characterize miR expression in various tissues (proximal and distal esophagus, stomach and duodenum) obtained from the upper gastrointestinal tract in preparation for the study of MiR in patients with Barrett's esophagus and other inflammatory conditions of the upper gastrointestinal tract.

The Evaluation of Patients With Esophageal and Foregut Disorders With WATS (Wide Area Transepithelial...

GERDBarrett Esophagus2 more

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.

Preliminary Longitudinal Validation of Biomarkers Predictive of Barrett's Esophagus

Barrett's Esophagus

Barrett's esophagus can progress to esophageal cancer, but it doesn't always. Current treatment is frequent surveillance via upper endoscopy with multiple biopsies to look for changes (dysplasia). Pathologists vary dramatically in their interpretation of Barrett's Metaplasia versus dysplasia and consensus is very difficult to achieve. The investigators propose a longitudinal study of subjects with confirmed Barrett's intestinal metaplasia without dysplasia to look for predictive factors for transformation to dysplasia or cancer. Potential biomarkers can be found in serum, plasma, urine, frozen or fixed Barrett's and Normal esophageal mucosa. In addition, the investigators are testing a brushing technique from CDx, Inc. for predictive factors. Subjects must have pathologically confirmed Barrett's intestinal metaplasia without history of dysplasia to be on this longitudinal study.

Optical Coherence Tomography of the Gastrointestinal Tract

Barrett's Esophagus With or Without DysplasiaPatients With Early Esophageal or Gastric Cancer1 more

Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light to create pictures of living tissues and has been successfully used to generate high resolution cross-sectional images of tissue in the human eye and skin. OCT systems are now commercially available for eye and skin use, and several clinical reports on the use of OCT in the gastrointestinal tract have been published as well. The purpose of this study is to develop a high-speed noninvasive OCT probe which can be placed through an endoscope for the early diagnosis of pre-cancerous and cancerous lesions in the gastrointestinal tract. This is a pilot clinical research study that is designed to advance OCT technology, which may in the future be able to replace or augment endoscopic biopsies.

Prevalence of Dysplasia of the Gastric Cardia

Barrett's EsophagusIntestinal Metaplasia1 more

We propose a tissue sample collection study for patients at UNC who have undergone or will undergo radiofrequency ablation therapy for Barrett's Esophagus (BE) or intramucosal adenocarcinoma as part of routine medical care. Purpose: To determine the prevalence of metaplasia and dysplasia in the gastric cardia before and after ablative therapy. To determine the incidence of cardiac metaplasia and dysplasia as a function of ablative therapy. To determine the correlation between dysplasia in the tubular esophagus, and dysplasia in the cardia. To assess the ability of immunohistochemical (IHC) staining of cardia tissues to predict incident dysplasia in the cardia. Several well-characterized biomarkers, including p16, p53, Ki67, cyclin D1, and cyclin A, will be assessed.
