Filter by:By affecting the gastroesophageal pressure gradient, obesity predisposes to reflux of gastric contents. The investigators hypothesized that the loss of weight will decrease this gradient and as a result decrease the severity and frequency of GERD symptoms. GERD negatively affects health related quality of life. Since loss of weight may decrease gastroesophageal reflux, the investigators hypothesized that it obesity contributes to poor quality of life in GERD subjects and losing weight should also favorably impact and improve quality of life in GERD patients.
This research is being done to study the safety of an investigational percutaneous endoscopic gastrojejunostomy (PEGJ) tube and whether the addition of a balloon on the end of the J tube prevents it from slipping back into the stomach.
The overall objective of this study is to obtain data to evaluate whether high-resolution imaging of the gastrointestinal mucosain vivo can assist clinicians in detecting dysplastic (precancerous) areas. This is an exploratory study of a confocal endoscope designed to evaluate the feasibility of using this FDA-approved device in the endoscopic surveillance of subjects at high-risk for neoplasia in the upper and lower GI tract. The confocal endoscope provides real-time in vivo microscopic images of the mucosa which resemble standard pathology.
The purpose of this retrospective, open-label, post-market study is to evaluate the safety and efficacy of Transoral Incisionless Fundoplication (TIF) performed with EsophyX (brand name) in a broad range of GastroEsophageal Reflux Disease (GERD) patients treated at high volume centers across the United States.
What's known? Prone position is no longer a treatment option for GERD because of the association with SIDS. Originally, positioning in an infant seat was recommended for infants with GERD. However, Orenstein proved this position has a detrimental effect on GER, compared to prone positioning. What's new? Positioning in an infant seat caused no increase in GER, compared with the supine 15 degrees anti-Trendelenburg position. Except for the number of long reflux episodes, which was significantly higher in the car safety seat. Larger trials are needed for decisive conclusions.
The study objective is to evaluate the relative merits, safety and effectiveness of Transoral Incisionless Fundoplication (TIF) in GERD patients currently treated with daily Proton Pump Inhibitors (PPIs).
The purpose of this study is to make Domperidone available to patients with gastrointestinal disorders who have failed standard therapy and who might benefit from it.
The purpose of this study is: - To study the components of the gastroesophageal junction high-pressure zone individually and as a group, by pharmacologically eliminating or accentuating the pressure profile generated by the smooth muscle components. - To differentiate the gastric sling fibers from the clasp fibers based on the spatial orientation of these muscle groups.
Although the symptomatic and epithelial (histologic and endoscopic) response to antireflux therapy are well known and extensively studied, little is known of the genetic events occurring in response to proton pump inhibitor therapy. Preliminary data from our laboratory has shown, for example, that COX-2 expression is not only elevated in patients with gastroesophageal reflux disease but also can be correlated with pathologic esophageal acid exposure on 24 hour pH monitoring. Similar studies have suggested that antireflux surgery may normalize COX-2 gene expression. In contrast studies following ablation of dysplastic Barrett's epithelium have shown persistence of genetic changes associated with altered cellular function, despite the return of the histologic appearance to normal. Several key mediators of inflammation, metaplasia (Barrett's) and neoplasia have now been well characterized and shown to be important factors in the pathogenesis of esophageal injury. It is likely that successful antireflux therapy returns altered expression of these mediators toward normal although this hypothesis remains largely unexplored. The aim of this study is to investigate gene expression of key mediators of the spectrum of esophageal mucosal injury and the response to antireflux therapy. Hypothesis: Antireflux therapy (proton pump inhibitor and surgical fundoplication) normalizes the expression of genes known to be involved in the pathogenesis of inflammation (esophagitis), metaplasia (Barrett esophagus) and neoplasia (adenocarcinoma).
The purpose of this study is to collect post-marketing data on patient outcomes and satisfaction following treatment with the Plicator™. The outcomes will be tracked through analysis of patient Quality of Life (QoL) questionnaires and medication use. The QoL and medication use questionaires will be administered and documented twice before the procedure and then again at outlined intervals following the procedure. Additionally, financial measures will be evaluated (i.e. pre-procedural and procedural time and costs, staffing/personnel needs during procedure, anesthesia and related costs, recovery time and associated cost, etc.) and post-procedure GERD-related medical history questionnaires will be completed. This post-market evaluation is a multi-center study design using the NDO Surgical, Inc. Plicator as the treatment device. Treatment efficacy will be evaluated by comparing QoL and medication use before and after treatment with the device. Patient follow-ups will be completed at 1 week and at 6, 12, 24, 36, 48 and 60 months post treatment.
